TERMS & DISCLAIMERS

warranty


It started as a one-man, part-time operation making engineparts for himself and his hot rod buddies more than 40 yearsago. Today it has evolved into a multimillion dollar, multifacetedmanufacturing operation, producing high performance engineequipment for a wide variety of applications, including cars,trucks, boats, tractors, motorcycles and antiques.

Crower Cams and Equipment Company, Inc., is a leadingproducer of aftermarket camshafts and valve train components.But over the years Crower has developed a more diverse line ofproducts. Today, Crower is the world’s largest manufacturer ofaftermarket crankshafts and connecting rods, and the Crowerline of clutches has been dominating the drag racing andtractor pulling series for nearly two decades.

EARLY THOUGHTSBruce Crower, president of Crower Cams, is the thinking man’sracer, saying, “People don’t think as much as they should. Ifyou think hard enough, the answer will come.” Born in 1930 toa church going family in Phoenix, Arizona, he has been thinkingabout, and implementing ways to improve the internal combus-tion engine for nearly six decades.

During high school, Bruce found that other hot rodders wouldbuy parts that he made for his own ’32 Ford roadster. As newideas came to mind, instead of making just one part forhimself, he would make several at a time and sell them to hisfellow hot rodders. It was simple arithmetic to see the profit ofmaking thousands of such parts and selling them nationwide.

INTRODUCTION TO FAST MACHINESIn 1949, a fast, 80 cubic inch Harley led to a 120 mph, 300cubic inch Merc-powered Deuce roadster that Bruce says was,“the first Arizona car to beat the bikes,”and his own successful speedshop near Phoenix, Arizona.Uncle Sam, however, hadother plans and he wasdrafted for the Korean war.

historyAfter 18 months on a ground crew in the Air National Guard,developing his mechanical skills in a machine shop at LukeField Air Force Base,he followed hisparents to San Diegoand landed a job as amachinist at PaulSchiefer Clutches. Allover California,especially at ParadiseMesa, people wereburning up thequarter mile.

THE CHRYSLER HEMIAnd despite the infamous Bean Bandits’ quantum leap from120 to 140 mph with a Bruce Crower built engine, theflathead’s reign was over theday Chrysler intro-duced its OHVHemi. Bruce wasquick to realize theHemi’s potential,and by 1954 he was shakin’ em up on the Bonneville salt flatswith a 157 mph record breaking run behind the wheel of hisHemi-powered Hudson. Credited with being the first to top-mount a GMC blower, Bruce had fashioned his own intakemanifold and a pulley system cast in coffee cans using oldpistons as material.

THE “U-FAB” INTAKE MANIFOLDThe intake/blower combo was a success, and not only putBruce in the record books but also in the manifold business.There followed the phenomenally successful Crower “U-Fab”do-it-yourself manifold. Consisting of two cylindrical runnersjoined with hoses andclamps, the “U-Fab”was designed to holdfour, six or eightStrombergcarburetors.

It wassimple,inexpensiveand extremelypopular. “We soldthousands of them,”according to Bruce.

Bruce was the first to top mount a GMC blower.


1955 - THE BEGINNING OF CROWER EQUIPMENT CO.With $312 in the bank Bruce booked a sixth page ad in Hot Rodfor $300. That one ad generated over $10,000 dollars worth oforders, and suddenly I was, “controlling my own destiny withmy own two hands, and the harder I worked, the more money Imade.” He worked until the wee hours of the morning assem-bling those kits, and finally hired his brother, Dave and eventualbrother in-law, Loren in order to keep the production up withthe demand. Thus theformation of Crower.

THE “GLIDE”Other speedmerchants eventu-ally followed hislead, tapping intoCrower’s market share. But Bruce and the boys had beenthinking ahead, this time about a double disc clutch first seenin a Fiat. Crower combined this technology with a Schieferclutch and applied it towards drag racing and, once again,enjoyed another overnight success with the“Crowerglide” centrifugal clutch. It quickly becamethe most popular clutch in drag racing.

CAMSHAFT TECHNOLOGYCrower, however, was already moving on, this time inthe direction of cam technology where once againthey took advantage of an industry in low gear. Theindustry’s shortcomings have always provided theimpetus for Crower’s ideas. Only the experiences atthe Indianapolis 500 Brickyard have caused him toreevaluate his direction.

THE INDY EXPERIENCEIn 1954, Bruce Crower was invited to work on the Offy-powered Dean Van Lines Indianapolis racing car withJimmy Bryan. They qualified onthe front row and finishedsecond. Six years later,working on JimRathmann’s team,all of their hardwork paid off asthey went on towin the 1960 Indy500. He went onto win again as amember of GrahamHill’s team, and againin 1967 as part of theA.J. Foyt team.

Subsequent years sawCrower cars equippedwith engines as diverseas a downsizedsmall-block Chevyand a customdesigned flat-eight withCosworth heads, whichreceived the 1977 SAE “LouisSchwitzer Award” for race cardesign. But over the years, in orderto remain competitive, teams started preparing year around forthe race, and Bruce decided that his time and money would bebetter spent investing in his own business in the area of highperformance engine parts and engine research.

STATE-OF-THE-ART MANUFACTURINGToday, Crower Cams and Equipment Company is still familyowned and operated, employing over 300 people at fiveseparate facilities. Utilizing the latest in computer assisted

design (CAD), Crower engineers render multidimensionalblueprints that are then downloaded into one of Crower’s state-of-the-art CNC machining centers. This allows more flexibility,with tighter tolerances, and gives the customer more choices.

Choices that include ten different styles of 4340 steelbillet or 6AL4V titanium connecting rods and four

variations of 4340 forged crankshafts, depending on thecustomer’s particular application, rpm range and budget.Crower also lists over 500 catalog camshafts, but, if a customgrind is desired, Crower has accumulated an extensive inven-tory of over 3000 master cam profiles to choose from in orderto obtain the correct duration and lift figures required.

The transition to a fully computerized design and machiningenvironment will only enhance Crower’s already superior line ofproducts. This, coupled with Crower’s extensive productdevelopment and testing program, keeps Crower and it’scustomers one step ahead of the competition.

RESEARCH & DEVELOPMENTAlthough Bruce Crower is no longer involved in the day-to-daymanufacturing operation, he spends his time designing anddeveloping newproducts at thecompany’sresearch anddevelopmentfacility locatedat his Jamulranch. ThisR&D facilityhouses acomplete machine shop and a fully operational, computercontrolled Heenan-Froude engine dynamometer, capable ofgenerating high levels of horsepower and torque on just about

any type of engine. Before Crower introduces a newproduct to the market, you can be sure it

has undergone a rigorous cycle of testing under dyno simu-lated racing conditions. Each Crower product is then evaluatedfor maximum horsepower and torque figures, as well as rpmspecifications to insure product reliability.

THE BONNEVILLE SALT FLATSIn addition to product testing and development, both ofCrower’s Bonneville race cars were completely designed andconstructed at the Jamul facility. A 1927 Model-T roadsterequipped with a 700hp 1931 straight-8 Nash engine, and astate-of-the-art streamliner powered by a turbocharged smallblock Chevy and a pair of prototype Crower 4-valve cylinderheads. He first touted the idea of a four-valve production headfor the small-block Chevy back in 1965 after inventing a headwith an inlet port on the same plane as the exhaust port. Chevyengineers were so impressed they had prototypes drawn andcast within 30 days. Unfortunately, the various race sanctioning

bodies indicated thatthey would have to banit because it wouldhave given certainracers an unfairadvantage. Thestreamliner, however,is in the UnlimitedClass and withthe help of theheads and someother radicaldesign solutions, itis projected to runover 440 mph at 1150horsepower on the Bonneville salt flats.

RECOGNIZING HIS DEDICATIONIn recognition of Crower’s innovative products for drag

racing, Bruce Crower was inducted into the DragRacing Hall of Fame located in Florida. An honor

and privilege that is the direct result of hishard work and dedication to the industry thathe loves so much.

USING QUALITY, AMERICAN MADE MATERIALSThe secret to Crower’s lasting success, according to DaveCrower, vice president and general manager of Crower, is thatbasically “we make what people ask for. We do it with betterquality than anyone else, plus we do it lighter, which is the keyto quicker elapsed times.” Not one to compromise the strengthand integrity of Crower’s products, Crower uses USA milledmaterials in its manufacturing. Although cheaper products canbe imported from other countries, the Crower philosophy hasalways been that “If a product ismade right the first time, usingthe highest quality materials andthe latest production methods, itwill perform flawlessly to it’sintended ability.”

VEHICLE PACKAGE

RPM POWER RANGE

LEVEL 1 CAMSMILEAGE & TORQUE

LEVEL 2 CAMSMILEAGE & POWER

It is the complete vehicle package that will determine how well your vehicle satisfies yourperformance preference.

By complete vehicle package we mean the interaction of all a vehicle’s components and sub-systems, including the engine and its related parts (such as the carburetor, intake manifold,exhaust system, camshaft and ignition), the transmission, rear end gears, wheel and tirecombinations and diameters and suspension pieces. All of these components must work inunison to produce the desired performance results.

Before thumbing through the collection of profiles listed on the following pages you will need toformulate a definite idea of your motoring requirements. Doing so will dictate what rpm powerrange you will be operating in most often (see Fig. 1). Because camshaft selection as well ascarburetion, manifold choice and gearing are based on it, knowing your rpm power range is thekey to building a successful vehicle package.

Be realistic when examining your driving style, the vehicle’s present engine/drive train compo-nents and your pocket book. Be sure you can afford to purchase all of the components neces-sary to complete the desired vehicle package at your performance level. Remember, the furtherfrom stock you deviate in the engine department, the more modifications will be requiredelsewhere in the vehicle.

Refer to the five performance levels listed below for an idea of the components required toproduce a successful vehicle package at the performance level you desire.

Approximate RPM Power Range:Hydraulic camshafts - Idle to 3500 / Redline: 4500.Solid camshafts - 1000 to 4000 / Redline: 5000.

Level 1 indicates a good stock replacement camshaft. These profiles are designed to enhancethrottle response and low end torque in vans, trucks, passenger cars and mild marine applica-tions while delivering fuel efficient motoring. High vacuum, smooth idle and maximum efficiencyare characteristics of these cams. Stock or small cfm carburetor, small diameter tube headersand dual exhaust are recommended for maximum benefit. Intended for stock or near-stockengines and drive trains, 8.5:1 compression, 2.70 to 3.25 ring and pinion, automatic transmis-sion with stock converter or four-speed manual transmission.

Approximate RPM Power Range:Hydraulic camshafts - 1500 to 4000 / Redline: 5500.Solid camshafts - 2000 to 5000 / Redline: 6000.

Level 2 profiles are for individuals that require more power and an extended rpm range. Workswell with stock or near-stock engines and drive trains. These camshafts provide excellent lowend and mid-range power for spirited street and offroad driving and mild marine applications.Modifications that should accompany installation of these cams include small diameter tubeheaders, low restriction dual exhaust, aftermarket manifold, increased cfm carburetor andreworked or performance ignition. Increased compression (9.5:1) is recommended for maxi-mum output. Aftermarket torque converter with slightly higher stall speed is recommendedbecause stock factory converters do not allow the engine to provide adequate idle speed and offidle performance. Works well with four-speed manual transmission. Designed for lightly modi-fied street engines.

camshaft selection


Approximate RPM Power Range:Hydraulic camshafts - 1800 to 4500 / Redline: 6000.Solid camshafts - 2200 to 6000 / Redline: 7000.Hydraulic roller camshafts - 2000 to 4700 / Redline: 6250.

Level 3 camshafts are designed for moderately modified engines. Intended for performance hotstreet/strip and performance marine applications, these profiles have a moderate lope at idle andoffer an extended rpm range with emphasis on upper bottom to top end power and a strongmid-range. These higher lift, longer duration camshafts demand close attention to rear endgearing and tire diameter combinations. The secret here is to pick a ring and pinion gear set andtire diameter that keeps the engine in its optimum rpm power range (see Fig. 1). These profilesperform well with four-speed manual transmissions or automatic transmissions if a high stalltorque converter is employed. Headers, dual exhaust, larger than stock carburetor, performancemanifold and increased compression (9.5:1 to 10.5:1) are required. Mild porting and largervalves will improve performance.

Approximate RPM Power Range:Hydraulic camshafts - 2000 to 6000 / Redline: 6500.Solid camshafts - 2500 to 6500 / Redline: 7500.Hydraulic roller camshafts - 2200 to 5000 / Redline: 6500.

Level 4 camshafts are designed for heavily modified engines. They have a definite lope at idleand are best suited for dual purpose hot street/drag strip, hot marine and oval track applications.These grinds exhibit strong mid-range to top end torque and horsepower. Headers, dual exhaust,large cfm carburetor, performance ignition and increased compression of 10.25:1 and above arerequired. Cylinder head modifications would be beneficial. Use with standard manual transmis-sion or automatic with high stall torque converter. Again, close attention to proper ring andpinion and tire diameter selection is imperative.

Level 5 camshafts are designed for fully prepared, high compression, all-out racing engines andchassis. Extensive cylinder head modification, bigger valves, lightweight valve train, titaniumvalves, maximum flow carburetion or fuel injection, racing gas, alky or nitro, magneto orelectronic ignition, performance rod and crank assembly and increased engine clearances arerequired for maximum benefit.

The wide selection of level 5 profiles enable the experienced engine builder to choose the propercamshaft for his particular application, whether it be drag racing, oval track competition, tractorpulling or performance marine. If you are uncertain as to which cam profile best suits yourneeds, please contact our technical support staff at 619-422-1191.

Cam core configurations differ between ’57-’87 and ’88-’92 Chevrolet engines and cannot be interchanged.BE SMART! Crower performance camshafts feature high lift, fast action features that can cause stock or other aftermarket valvetrain components to fail. Be sure to use a Crower engineered kit to avoid possible damage.For severe-duty applications, Crower recommends running the high-lube “CamSaver” lifter that channels more oil to the cam/liftersurface (#66000X3-16).Valve timing events are available online at: www.crower.com/valvtime.html

Note: If using longer than stock valves you may require spring and retainermodifications. See specs or contact Crower.

CROWER CAM BREAK-IN PROCEDUREThis applies to all hydraulic and solid lifter camshafts using higher than stock spring pressure:• Do not use block restrictors in the oil galleys. This severely limits oil flow to the cam, lifters and overhead.

• Break-in cam and lifters with low pressure springs only. Do not exceed 225 to 250 lbs open pressure.• During break-in run engine for 35 to 45 minutes and vary rpm from 2000 to 3000.

• Recommend adding Engine Oil Supplement (EOS) or equivalent to fortify oil. Use Crower #86084.

• For break-in procedure Crower recommends 10W/30 motor oil. Heavier weight oils do not cold flow.• Do not use synthetic oils during break-in period.

• For further information, please refer to the Crower Installation booklet that accompanies the camshaft.

* Machine work required, specify 11⁄32 pilot shaft when ordering.Cam core configurations differ between ’57-’87 and ’88-’92 Chevrolet engines and cannot be interchanged.

For severe-duty applications, Crower recommends running the high-lube “CamSaver” lifter that channels more oil to the cam/liftersurface (#66000X3).

Note: If using 3.750" stroke or above cranks contact Crower for smaller base circle camshafts for more rod clearance.BE SMART! Crower performance camshafts feature high lift, fast action features that can cause stock or other aftermarket valvetrain components to fail. Be sure to use a Crower engineered kit to avoid possible damage.CAUTION! When using high lift cams pay close attention to retainer, oil seal and valve guide clearance at full lift (minimum .050")

LIFT RULE CAMSHAFTS: Crower has a complete line of camshafts that will satisfy any max lift requirement.


Note: If using longer than stock valves you may require spring and retainermodifications. See specs or contact Crower.REMEMBER! Increasing rocker ratio on intake (1.6) will make the camapproximately 5° bigger for more top end.HIGH RPM! Crower highly recommends the use of rollerized rockers. Seerocker section for ratios and stud diameters.These camshafts will work with the following carburetor sizes:350 (210 cfm), 390 (410 cfm), 500 (350 cfm).If you can supply cylinder head flow data, engine specs, operating powerranges and exhaust manifold configurations we will be able to grind you acamshaft that is far superior than any other brand currently available.

* These cid engines (383, 406) require a smaller base circle for 3.750" or larger stroke cranks. Add an “S” at the end of desired cam part number (example: 00275S) if smaller base circle is desired.

*86781-16 and 86767-16 retainers require Super 7° keepers. Titanium valves required to achieve high rpm.

Due to the wide variety of valve train combinations (i.e. lifter bore diameters, offsets, valve lengths, installed heights, etc...),we highly recommend that you contact Crower for your specific valve train needs.

Note: When ordering a .930" - .950" base circle cams for 3.750" or larger stroker cranks, add an “S” at the end of the part number.Example: 00432S. For strokes of 3.900" or larger contact Crower for .850" base circle camshafts.

HIGH RPM! With today’s high engine rpm and increased rocker ratios, valve train life is extremely critical. Increased springpressures are mandatory for insuring reliable valve train life. Contact Crower’s technical assistance department for proper highrpm recommendations.

INTEGRAL CAST IRON GEAR OPTION: Premium 8620 steel billet, copper plated cam cores with integral cast iron cam gear areavailable from Crower on a special order basis (specify part number 00050). Crower highly recommends using the factory stockcast iron distributor gear for extended cam and distributor gear life.Valve timing events are available online at: www.crower.com/valvtime.html

CROWER CAM BREAK-IN PROCEDUREThis applies to all hydraulic and solid lifter camshafts using higher than stock spring pressure:

• Do not use block restrictors in the oil galleys. This severely limits oil flow to the cam, lifters and overhead.• Break-in cam and lifters with low pressure springs only. Do not exceed 225 to 250 lbs open pressure.

• During break-in run engine for 35 to 45 minutes and vary rpm from 2000 to 3000.

• Recommend adding Engine Oil Supplement (EOS) or equivalent to fortify oil. Use Crower #86084.• For break-in procedure only, Crower recommends 10W/30 motor oil. Heavier weight oils do not cold flow.

• Do not use synthetic oils during break-in period.• For further information, please refer to the Crower Installation booklet that accompanies the camshaft.

Note: If engine is equipped with exhaust valve rotators see rotation eliminator cups.

Note: For proper oiling on 1965 and 1966 engines, rear cam bearing must be grooved. Specify when ordering cam.Note: Two-gear drives and reverse engine rotation camshafts are available on a special order basis.

BE SMART! Crower performance camshafts feature high lift, fast action features that can cause stock or other aftermarket valvetrain components to fail. Be sure to use a Crower engineered kit to avoid possible damage.

For severe duty applications, Crower offers a high-lube “CamSaver” lifter that channels more oil to the cam lobe and lifter surface.Specify lifter 66000X3-16 when ordering corresponding component kit.

CAUTION! When using high lift cams pay close attention to retainer, oil seal and valve guide clearance at full lift (minimum .050").Do not exceed .550" gross lift using stock rocker arms.

Note: Early 348-409 cid 1958-1965 cam cores are available from Crower on a special order basis.Valve timing events are available online at: www.crower.com/valvtime.html

Note: The above solid profiles are ground with a smaller base circle than stock. If using stock length valves, you must use .055" thick lash caps (86126-8) in kit below. Check follower geometry with Dykem hi-spotblue or any other non-drying compound and adjust valve length accordingly (see diagram 1). Duration numbers @ .050" have been refigured to reflect valve lift.

Note: Ford overhead camshafts are susceptible to lobe wear. We highly recommend breaking in new cam and followers with a lightpressure break-in spring for a minimum of 30 minutes.

Note: If using longer than stock valves you may require spring and retainer modifications. See specs or contact Crower.

CONVERSION KITSPart No. Remarks

Comes with heavy duty adjusters, nuts, sleeves and stabilizer spring.

Note: Lift rule camshafts are available from Crower on a special order basis.

Note: The above solid profiles are ground with a smaller base circle than stock. If using stock length valves, you must use .100" thick lash caps (86127-8) in kit below. Check follower geometry with Dykem hi-spotblue or any other non-drying compound and adjust valve length accordingly (see diagram 1). Duration numbers @ .050" have been refigured to reflect valve lift.Note: Lift rule camshafts are available from Crower on a special order basis.

Note: If keeper height is longer or shorter than correct height (± .050" tolerance), contact Crower for a recommendation.

* Machine work required, specify 11⁄32 pilot shaft when ordering.Note: If using Boss heads contact the factory for special spring and retainer recommendations. Boss 302 engines employ a 1.73rocker ratio, so the gross lifts listed on this page, as well as the previous page, are incorrect for the Boss 302. To figure the correctgross lift for Boss 302 heads divide the gross lift listed by 1.6 (lobe lift) then multiply the lobe lift by 1.73 (Boss 302 rocker ratio).

Note: Camshafts for 289/302 cid engines can be used in 351W engines by changing the firing order to 1-5-4-2-6-3-7-8.Some early Ford heads use 5⁄16 valve stems. Please specify when ordering as the above kits are designed for 11⁄32 stems.

COMPETITION PROFILESWhether you’re running the Type 1, 3 or 4 engine, Crower has hundreds of cam profiles that willdeliver increased performance. Call with the following information for a proper recommendation:• Engine specs (bore, stroke, etc...).• Connecting rod length.• Intake and exhaust flow figures (intake and exhaust manifold lengths).• Intended operating power range and type of fuel.• Data on your best existing camshaft .• Rocker ratio information (intake and exhaust).• Installed valve spring height (see diagram 2).• Conventional flat tappet (cast iron), hardface or roller tappet (Type 1 and 3 only).If budget considerations are not an issue, roller tappet profiles (conventional or inverse radius) deliver the highest lift rates perdegree, producing more area under the lift curve, as well as reduced friction, therefore increasing horsepower and torque.

VELOCITY/SPEED

Lobe area is derivedfrom duration and lift.Used for comparison.

DURATION AT LIFT

Opening and closing velocity speedsare checked at three positions over a30° cam and 60° crank movement toinsure accurate lobe comparison data.

Duration is checked at sevendifferent positions of lobe lift. Use

these numbers as you would aduration graph for comparison.

Average foot is thecontact pattern of the

lobe on the lifter surface.

If you’re lacking performance, send Crower your used ordamaged camshaft for complete lobe analysis and regrindingor repair. Cams will be straightened and then checked-out(sample shown above) to establish original specs. A Crowertechnician will analyze all of the data and, based on yourperformance parameters, regrind your cam to desired specs.

#1 TOURING PROFILE (250F)(Solid Lifter) Improves entire rpm range from 1000 to 6000.Smooth idle. Stock applications with no more than 10.5:1 compression.

#2 RALLY SPORT PROFILE (264F)(Solid Lifter) Slight lope at idle. Improves rpm range from 1500 to 6500.Greatly improves high gear acceleration for passing and hills.

#3 SLALOM/AUTOCROSS PROFILE (270F)(Solid Lifter) Slight lope at idle, but smooth into the throttle. Improvesrpm range from 2000 to 6700 plus. More power for passing and hills.

#4 CLUB RACER PROFILE (284F)(Solid Lifter) Racy lope at idle. Extends rpm range from 2500 to 6500with redline at 7100 plus. Increased compression, valve pocketing incombustion chamber and added carburetion will enhance total power.

#5 COMPETITION PROFILE (290F)(Solid Lifter) Race only. Very rough idle, especially with addedcarburetion. Higher compression pistons or head milling advised as peakhorsepower develops in 5500 to 6500 rpm range.

#6 ROAD RACING PROFILE (304F)(Solid Lifter) Race only. Requires extensive modifications like 13:1compression, grouped exhaust system, individual carburetion, inlet valvepocketing and engine balance. Rpm range from 4500 to 8000.

ADVANCE & RETARDCAMSHAFT BUSHINGS

Using Crower camshaft bushings is theeasy way to “tune” your camshaft timing.You’ll receive five advance or retard bush-ings that are individually stamped to dis-play amounts advance/retard in camdegrees (0°, 1°, 2°, 3°, 4°). Features ashouldered lip that retains the bushingand eliminates fallout.

CAM THRUST PLUGSRoller cam lobes are ground flat, withoutthe taper found in hydraulic and solidlobes. The cam thrust plug sits betweenthe front of the timing gear and the backof the front cover and prevents forwardcam travel and ignition flutter in rollergrinds. Available in choice of two styles:phenolic (non-galling material) or fullyrollerized for reduced friction.

HYDRAULIC LIFTERSCrower hydraulic lifters will complimentany hydraulic cam. Features ball-checkoil control valving, precision radius facesand quick break-in. New lifters must beused when installing a new camshaft toavoid premature lobe and lifter wear.

CAMSAVER HYDRAULICLIFTERS

The maximum in cam lobe and lifter life.If high spring pressures or extreme andunusual operating conditions have youworried about lobe scuff and lifter wear,insist on Crower “high-lube” CamSaverlifters. These lifters deliver 20% to 30%more oil to your lobe and lifter faces forthe best possible insurance against pre-mature lobe and lifter failure. Speciallymachined flats put 12 to 16 ounces ofadditional oil per minute at each lobe with-out adversely affecting engine oil pres-sure (nominal drop of just 1 or 2 pounds).Crower CamSaver lifters incorporate thesame precision ground radius face andfinish as our standard lifters to insurequick break-in and trouble free operation.

Back in 1957, Crower pioneered the very first aluminum shaft rock-er arm assembly mounted on a stock small block Chevy cast ironcylinder head. The race was the Indy 500 and Crower has beenmaking high quality rocker arms ever since.The weak link in any pushrod engine is the rocker arm and rockerstiffness is an important factor toward developing horsepower.Crower is making an effort to raise the bar substantially toward per-fecting shaft rockers for high performance engines.

Of course, we didn’t do it in a vacuum. Over the decades of workingwith you, the racers and engine builders, we’ve learned to study theproblems you encounter. We’ve made note ofyour wish lists. We’ve scrutinized failedcomponents...done our home work!Consequently, we’ve been able to consis-tently offer solid, viable, cost effective solu-tions that do not compromise strength. You’ll find that all our stud and shaft mount rocker arm systemsachieve the critical balance of lightweight without compromisingenduring strength. Crower valve train components are characteristi-cally strong, able to maintain dimensional integrity under load andat high rpm so valve actuation is extremely accurate. Our rockersystems are well thought out with regard to proper geometry,minimizing friction and heat build-up so the parts live and rpmfreely. The shaft setups are user friendly so they are easy to workon at the track and provide accurate, repeatable valve adjustment.Crower rocker systems (stud or shaft mount) are available for most popular cylinder heads, often in yourchoice of material, stainless steel or aluminum.Crower Cams & Equipment Company...good materials, state-of-the-art production facilities and savvy engineers solving problems withcreativity, technology and common sense. The result? The finestvalve train componentry you can equip yourself with! You’ll find nobetter rocker systems available at any price!

Highest unit loading on the valve train is

approximately at halflift (45° @ cam lobe)

Ideal rockergeometry athalf valve lift

Higher rocker ratios requireextending the arm of the rocker.Long arm rockers allow properpushrod seat positioning in rela-tion to the fulcrum point. An addi-tional long arm benefit is reducedback and forth tip travel across thevalve stem. Less scrubbing andvalve stem side loading occur and associated frictional losses areminimized.

Rocker arm ratio is determinedby dividing the distance from thefulcrum to the tip centerpoints(Y) by the distance from the ful-crum to the pushrod seat center-points (X). This theoretical ratiomay vary from our net/advertisedratio due to measured valve traindeflection under load.

contact slightly behind centerlineNo Lift

At highest unit loading(approx. 1/2 lift) tip contact ideally is on the centerlineof the valve. The valve train isovercoming spring pressure and,more importantly, rapidly acceler-ating its mass. To minimizedeflection, side loading and fric-tional loss, we want the valvetrain geometry in its strongestand straightest configuration at this point.

This configuration minimizes tip travelacross the valve stem and keeps contactcentered on top of the valve, reducing fric-tional losses due to valve guide side loadingand tip scrubbing. Pushrod deflection is also minimized for more accurate valve action.

needle bearing tip option

Crower has raised the bar on valvetrain technology with a new needlebearing roller tip option available onall new Crower stud and shaft mountrocker arm assemblies.

Results are greatly reduced frictionfor added horsepower and reducedvalve guide and valve stem wear.

The lighter tip delivers greater valve controlfor increased rpm and improves valvespring longevity by decreasing heat overtraditional non needle designs.

If you’re not sure or don’t know which CrowerShaft Rocker System will fit your cylinder head, orthe type/model of head you have and need help,follow these simple procedures:

1. You’ll need to provide us with some critical information and dimensions. a. Cylinder head manufacturerb. Engine typec. Intake and exhaust valve distances from

cylinder head centerline.d. Rocker stud spacing from cylinder head

centerline.Here’s how you do it.

Measure the distance between the centerlinesof the two inboard exhaust valves and record thevalue. If you divide this measurement in two you’llknow the distance each valve is from the cylinderhead centerline.

Now measure the distance between the centerline of the exhaust valve and the centerlineof the intake valve.

2. Follow the same procedure for the studs.3. Supply us the dimensions and we’ll take it

from there!

ROCKER ARMS

Made from 17-4PH stainless steel with 1025 heat-treating, these proven rollerized rockers feature pre-mium, oversized needle bearings, sure-lock rockernuts and alloy steel tip rollers. Superior lightweightbody design provides plenty of clearance for largediameter springs (1.560"). Includes sure-locks.

Crower’s Long Arm/Backset trunnion rollerizedrockers are made to the same high tolerances asour standard stainless steel rocker arms with a.090" backset trunnion and these added features:• Increased area under the lift curve• Additional spring clearance (1.650")• Smoother valve action• Less side loading on stems/guides• Drop on installation• Set of 8 for intake (use standard Crower stainless

steel rockers on exhaust)

Crower’s self-aligning rocker arms are available forlate model small and big block Chevrolet, DodgeMagnum truck and the V10 Viper.Features include:• Self aligning roller tip holds rocker in place• 25 hp, 4 mph on 1/4 mile with 1.7’s on V10• Emissions Legal certified ARB #D-410

Crower’s stamped steel rockers utilize a longer slotfor high lift, aftermarket cams. Made from highstrength steel alloy and stamped to resist the rockerflex for the longest possible operating life.

When installing a .100" long valve, the rocker arm tipmust be backed up .050" to insure centerline contactat half lift. Crower offsets the rocker stud hole in thetrunnion, pulling the rocker tip back into correctalignment with the valve stem. Re-establishing cor-rect geometry reduces valve guide wear and pro-motes more accurate valve timing.

LATE MODEL ROCKERS

DODGE MAGNUM ROLLER ROCKER KITSOur “PK” kits are a must in order to maintain valvetrain integrity when RPM’s over 5500 are reached. Ifsustained high RPM is expected, you must upgradeto 68305X1 spring. “PK” kits include rocker studs,guide plates (#70518) & 1 pc. pushrods (#69695).

* “K” incl. rocker studs. 5500 RPM limit on “K” kits (6300 on Viper).

NEEDLE BEARING TIP OPTIONAll Crower stud and shaft mount rocker arms are availablewith Crower’s new needle bearing roller tip option. Resultsare greatly reduced friction for added horsepower andreduced valve guide and valve stem wear. The lighter tipdelivers greater valve control for increased rpm and improvesvalve spring longevity by decreasing heat over traditional nonneedle designs. Specify #73715R option for stainless steel(stud or shaft) or #72915R option for aluminum (stud orshaft) when ordering rocker arms.

ALUMINUM STUD ROLLERIZED ROCKERS

ALUMINUM CENTERLINEROLLERIZED ROCKERS

OFFSET ALUMINUM INTAKE ROCKERS

BREAK-IN ALUMINUMROLLERIZED ROCKERS

Crower’s Enduro aluminum stud mount rocker armsare fully CNC machined from USA made, premiumaluminum extrusion. Crower’s unique “full arch”design reduces the rocker flex found in otherbrands. Results are increased rpm, greater areaunder the lift curve and added spring clearance(1.625"). Double-step, serrated pins feature ourrotor clip design that eliminates pin loosening. USAmade needle bearings. When vertical valve coverclearance is an issue, specify “LP” when ordering.

When installing a .100" long valve, the rocker armtip must be backed up .050" to insure centerlinecontact at half lift. Crower offsets the rocker studhole in the trunnion, pulling the rocker tip back intocorrect alignment with the valve stem. Re-establish-ing correct geometry reduces valve guide wear andpromotes more accurate valve timing.

Crower has a .150" offset aluminum rocker availablein 7/16” stud diameter only. These rockers includethe same features as our Enduro Aluminum rockers,but in an offset design. Order only for the intake andthen 8 only standard stud mount rockers on theexhaust (see p/n at left).

Reduce cam and lifter break-in failures by runningCrower’s new break-in rocker arms first. Features areverse offset trunnion (.050") that repositions thepushrod closer to the stock position. In other words,Crower moves the rocker arm and pushrod forward.050" for easier installation. Current break-in rockerson the market only offer center trunnion stud holepositions that require extensive cylinder head modifi-cations to the pushrod hole in order to achieve prop-er pushrod and head clearance. Crower’s break-inrockers drop on with no machine work required.Spring pockets machined for 1.560" O.D. spring

shaft-mounted rocker armsstainlesssteel

For those of you that feel most confidentrunning a valve train based in steel, weoffer you the Crower collection of shaftmounted stainless steel rocker arms. Eachand every configuration has been reli-giously scrutinized to offer extreme rigidityand accuracy while optimizing moment ofinertia phenomena/condition. Crower engineers made ease of installationand maintenance a top priority so you’llnever waste a moment when time is criti-cal at the track. Our stainless steel shaftrocker systems are a perennial favorite ofgrand national racers and marineendurance competitors.Sustained high temperature has little affect on the strength properties ofstainless steel so components made fromthis material should have a longer lifeexpectancy than similar components madefrom aluminum.

aluminumshaft-mounted rocker armsEach of our Aluminum Shaft Rocker configurations is impeccablydesigned and produced to maximizevalve train rigidity and accuracy whileoffering a minimal amount of recipro-cating mass. We have utilized the longest armlengths practical for each application. The results are minimalrocker tip travel and associated fric-tional losses as well as the capabilityto accommodate large diameter valvesprings with ease.Speaking of ease, these set-ups allowfor the quickest at-the-track valvetrain modifications around. Any taskthat requires rocker removal can be performed without concern forabsolute accuracy and repeatabilityupon reassembly.

AND THE DESIGNTake a close look at a Crowerod and you’ll notice that itis shaped like no other rod in the industry. Everycontour is designed to enhance overall strength andreliability at high engine rpm. Crower connecting rodsincorporate an “I-beam” design that eliminates pocketsof excess material and delivers exceptional longitudinaland horizontal strength. For those who prefer an “H-beam” design, Crower also offers this style of rod on acustom order basis. The cap screw design assures trueroundness and a positive bearing seat under severeload factors, a key factor in eliminating rod bearingfailure. Tolerances are to an exacting ±0.0001" of aninch to insure trouble free installation.

THE BOTTOM LINEWhen you install a set of genuine Crower connectingrods in your high performance engine, you can restassured that the design expertise, material and crafts-manship used during production are working hard tomaximize your racing effort. It’s the kind of dependabil-ity and confidence factor that can put you in thewinner’s circle. Crowerods are available for mostdomestic and foreign applications, as well as motor-cycle, industrial, vintage and one only prototypes.Crower’s enviable reputation and proven success has

led to imitations from competing manufacturers. Keepin mind that copied parts cannot maintain

Crower’s sophisticated design andproduction methods. Protect

your investment byinsisting on only

genuine Crowerodsfor your high

performanceneeds.

CROWERODSIn independent tests and under actual racing conditionsCrower connecting rods have proven to be the strongest,most reliable competition connecting rods available onthe market today. Crowerods were the first to survive the10 million cycle General Motors torture test, with GMengineers reporting that the Crower billet connecting rodwas the absolute strongest rod they’ve ever tested.

THE CROWEROD DIFFERENCEAn extensive effort in Computer Assisted Design (CAD),as well as rigorous dyno and track testing have beenexpended to perfect these failure free designs. Whenyou employ a set of genuine Crowerods you do so withthe knowledge and peace of mind that each rod willperform flawlessly, without fatigue or failure. That’swhy they’re the hands down favorite of the majority ofprofessional and amateur engine builders throughoutthe world.

IT’S THE MATERIAL...While other manufacturers are cutting corners, usingimported or low grade materials, Crower has kept costsdown without lowering our standards. Every rod wemake is hand craftedfrom Americanmade, 4340chromoly(chromium-molybdenum)steel or 6AL4Vtitanium toinsure the bestquality andreliabilitypossible.

MIDWEIGHTBILLET6.000"

STEEL BILLET ROD WITH 12 POINT CAP SCREW BOLTUnquestionably the most critical part of a high performance, internal combustion engine is the connecting rod.Connecting rods support the primary tension loads caused by engine operation in each revolution or cycle of thecrankshaft. Therefore, it is of utmost importance that the rods you choose to put in your engine are made fromonly the highest quality materials, manufacturing methods and fastening systems available on the market. Forover 25 years, Crower has been meeting this challenge. Only the finest, USA made 4340 chromoly (chromium-molybdenum) steel is used in the production of Crower steel billet connecting rods. Every rod is fully CNCmachined to remove all surface imperfections, 100% magnaflux inspected and checked for surfacehardness, then machined to final size to exacting tolerances within 1⁄1000" of an inch. Each set ofrods is fully balanced and then shot peened to achieve the ultimate in strength and reliability.The last, yet probably most important aspect of Crower’s connecting rod production cycleis the fastening system employed. Choose from premium H-11 tool steel rod bolts orAMS5844 bolts available as an upgrade.

Special “pressure fed” oiling hole from bigend to pin end is available on “H-Beam”billet Crowerods. Specify #90798 option

when ordering.An assortment of computer designedbeams are available for different

horsepower and weight requirements.

Only Crower offers you, theengine builder, the choice of“I-Beam or H-Beam” design.

CROWERH-BEAMDESIGN

CROWER “H-BEAM” CONNECTING RODSAlthough Crower is know mostly for it’s “I-Beam” rods, we

also build a variety of European influenced “H-Beam” designsas well. The thicker cross sections of the H-Beam are bettersuited for the EDM oil hole that runs the length of the beam

delivering added oil to the pin. Weights are equivalent toCrower’s standard “I-Beam” billet rod. To order specify “H”

before desired part number. For Pressure Fed Pin optionspecify #90798 after rod part number.

Pin boss dynamics are critical whendesigning a high performanceconnecting rod. To maintaintrouble-free operation, Crower beefsup the pin eye area.

6AL4V TITANIUM RODSThe demands made on a connecting rod, especially in aracing engine, are hard to visualize. Titanium allowsstresses to approach the breaking point for considerablylonger periods than an equivalent steel or aluminum rod.Crower uses only aerospace quality, 6AL4V titanium inthe manufacturing of our billet titanium Crowerods.Titanium has a lower thermal expansion rate than steeland much less than aluminum, which allows the racer tohold closer tolerances within the engine. Crower offers awide variety of applications available to choose from.Everything from a 4 cycle motorcycle to a 7.650" longbig block Chevrolet for Pro Modified. All Crower titaniumconnecting rods are equipped with cap screw bolts andstroker design to insure plenty of camshaft and caseclearance, also reducing weight in noncritical areas.

Extremely reliable H-11 tool steel bolts,rated at 220,000 p.s.i. or new aircraftquality, AMS5844 alloy bolts that are

corrosion resistant and rated at 285,000p.s.i. Both feature 12-point heads.

Special plasma sprayed sidesprevents galling that occurs when

titanium rubs with steel.

TITANIUMPRO MOD7.650"

Additional oiling hole insuresmore than an adequate amount oflubrication at the critical pin end. All titanium rods come

standard with aluminum/bronzebushings.

Custom rods available in anylength center to center, pin end

size and big end I.D.

Crower uses only 6AL4Vtitanium, with a composition of

6% aluminum and 4% vanadium.

Hollow dowel alignment fasteningsystem provides positive cap

alignment and “no hassle” removal.

AMS5844 ROD BOLT UPGRADECrower now offers a new AMS5844 rod bolt upgradeoption available for all steel billet and titanium rods.Highly recommended for extreme duty rpm andendurance applications.

CROWER CRANKSHAFTSChoose a Crower crankshaft and you’ll get the finesthigh performance crankshaft made. The Crowercrankshaft facility is like no other in the industry,utilizing massive, state-of-the-art CNC machiningcenters that work in unison, alongside seasonedmaster craftsmen. Crower crankshafts incorporate theunique combination of precision and attention to detailwith high production capabilities, in a wide variety ofdesigns and applications.

THE MATERIAL100% made in the USA, aerospace quality, vacuumdegassed, 4340 chromoly steel is drop forged to formthe strongest, most durable crankshaft money can buy.Some manufacturers put fancy, high tech names onthe materials they use in their crankshafts. A goodmarketing tactic, but nothing more. The truth is, for themanufacture of high performance crankshafts, there isno better material than the SAE certified,4340 “Non Twist” chromoly steel used inevery Crower premium crankshaft. Itis far superior to all other alloys inits ability to resist torsional torqueand maintain its dimensionalsoundness and integrity. You willnot find a better crankshaft, thana genuine Crower crankshaft.

MANUFACTURINGCrower is the world’s largest manufacturer of highperformance crankshafts. We have created a veryeffective combination of streamlined production capa-bilities and quality engineering that produces bettercrankshafts, quicker and more accurately than anycompeting crankshaft manufacturer. It’s called Crower“science,” and it emphasizes creativity rather than dullroutine. This gives Crower an unfair advantage andallows us to develop such innovative designs as the“Ultra-Light” crankshaft and the exclusive Crower“straight-shot” oiling system.

GUARANTEEDWhen you purchase a Crower crankshaft you’ll get aquality piece, manufactured from the finest materials toexacting tolerances, that goes unmatched in the highperformance industry. You are guaranteed precisionindexing and throw-to-throw consistency that some

engine builders swear isabsolutely perfect. When

you install a genuineCrower crankshaft in

your engine, you’ll doso with the peace ofmind that it willperform flawlessly,without fatigue or

failure.

Entry holes for the rod feed are located at the O.D. ofthe main, allowing oil to flow equally and unrestrictedto the bearings. This is key to prolonging bearing life.

The unique teardrop scoop and exclusive Crower“straight-shot” oiling system increases critical oil flow

from the main bearings to the rod bearings.

Looking from the rod, back up through the main, youcan see daylight, indicating it’s a genuine Crowercrankshaft with the “straight-shot” oiling system.

A TYPICAL SCENARIOFor years you’ve been running a stock crank and havenever experienced rod bearing failure. You decide to“step-up” and replace your stock crank with anaftermarket brand. Immediately you encounter bearingscuff or total bearing failure. This scenario happensoften, much to the dismay of the engine builder.

THE REASONOn most aftermar-ket brands the rodfeed hole is onlydrilled to thecenterline of themain. This methodof drilling doesn’tdeliver enough oilto the rod . Thiscreates a highcentrifuge, highpressure zone atthe main, restrict-ing critical oil flowintended for yourrods. As enginerpm increases thiscentrifuge effectgets worse, possi-bly resulting insevere crankshaftdamage or eventotal engine de-struction. Not theperformancecharacteristics youexpected when youswitched to anaftermarket brandcrankshaft.

THE SOLUTION – STRAIGHT-SHOT OILINGAfter extensive research and design, Crower engineersdeveloped the straight-shot oiling system and virtuallyeliminated bearing burnout and customer complaints.It features two Crower exclusives, off-center drillingand the teardrop design oil hole, which scoops oil atthe main and forces it into the rod feed hole. Althoughit’s time consuming, we feel it’s worth it.

THE PROVEN FACTSIt has been proven time and time again, “the lighterthe parts, the quicker the throttle response.” This is nomore evident than in the components that make upthe bottom end of an engine. Reducing a crankshaftscounterweight mass is critical in getting quickeracceleration and deceleration. It also alleviates stressand engine wear and improves oil shearing in the pan.

REVOLUTIONARY DESIGNThe Crower Ultra-Light crankshaft redefines the term“light rotating mass” by attaining just the right ratio ofsmaller O.D. counterweight with an exclusive light-weight crank pin web area. By lightening the crank pinweb area we are able to CNC excess material from thecenter of the counterweights without adverselyeffecting balancing. This is Crower’s patented pendu-lum undercutting. Lighter than any other crankshafton the market, the Ultra-Light is structurally just asstrong, and no more difficult to balance. Althoughcompeting manufacturer’s claim to have comparabledesigns similar to the Crower Ultra-Light, consider thefact that it takes much more than just scalloping outthe center of the counterweight to achieve the correctcombination of light rotating mass and proper bal-ance. Crower pioneered pendulum undercutting thecounterweights back in 1989.

PENDULUM UNDERCUTTING ANDLIGHTWEIGHT PIN WEB AREA

Smaller O.D. design placesheaviest mass closer to the centerof the crankshaft for the quickest

engine acceleration possible.

44.3% less frontal area improveswindage and oil shearing in the pan,two external forces that frequently

disrupt a crankshaft’s uniform motion.

The shorter, narrowercounterweight reducestotal overall mass andhas less frontal area.

Crower’s exclusive lightweightcrank pin web area allows the

counterweights to be pendulumundercut to reduce weight without

the need for heavy metalbalancing on most applications.

CROWER’S“Ultra-Light”

The “Klose’s StressConcentration Reduction”

distributes stress evenly overthe entire overlap area.

Crower’s “counterweight correct”design produces optimum

counterweight positioning for thebest possible bearing loading

and proper balancing.

Crower high performance rod bearings are qualityengine bearings designed to withstand the extremeloads of professionally tuned racing engines. Fea-tures high strength copper-lead in the load area forsuperior strength and embedding. Lead overplate pro-vides excellent fatigue strength and superiorconformability to compensate for distortion and/ormisalignment. Superlative bearing-to-bearing size con-sistency enables you to “build-in” the exact oil clear-ance you require, while narrowed and chamferedversions are available for large fillet journals whereadditional clearance is necessary. If running alumi-num rods, Crower has chamfered rod bearings withdowel pin holes.

Crower high performance main bearings offer profes-sional racers and engine builders the extreme accu-racy and bearing-to-bearing consistency required tobuild an engine that can handle the extreme loadsassociated with high performance racing. Featureshigh strength copper-lead in the load area for supe-rior strength and embedding. Lead overplate pro-vides excellent fatigue strength and superiorconformability to compensate for distortion and/ormisalignment. Crower high performance main bear-ings are designed to deliver improved bearing-to-bore contact for better heat transfer and a reductionin high rpm bearing chatter and/or failure. Available innarrowed and chamfered, for use with large filletjournals. A must when running any Crower crank.
