The Absolute Leader In Valve Train Performance

WINNING CAMSHAFTS DON’T HAPPEN BY ACCIDENT AT COMP CAMS® NOTHING ESCAPES OUR THINKING. RESEARCH, DESIGN, MANUFACTURING AND TESTING; WHEN IT COMES TO YOUR NEXT CAMSHAFT, NO DETAIL IS TOO SMALL. It is a well-known fact that many companies can go through the motions of grinding camshafts. However the horsepower ultimately delivered by a camshaft is determined long before it ever reaches a grinding machine. The fact of the matter is that regardless of how well the grinding process is executed, a camshaft is only as good as the design and engineering being applied. Camshaft lobe profiles control the critical opening and closing of the valves - the single most important factor for creating race-winning horsepower. That’s why COMP Cams® invests more in research and development than any other cam manufacturer in the world.

By selecting a COMP Cams® camshaft you can rest easy knowing that COMP has invested thousands of hours and millions of dollars to ensure that every detail has been optimized to out-perform the competition. In racing, there are many areas to save a few dollars; a camshaft is not one of them. That’s the real truth about camshafts.

BETTER ENGINEERING IS THE REAL HP SECRET

CAM HELP® CAN HELP

Sure, we utilize state-of-the-art cam grinding equipment operated by expert craftsman with decades of experience. But the real secret to making more usable horsepower can be traced to the COMP Cams® engineering department, the largest in the industry. They spend thousands of hours designing and testing camshaft concepts until the optimal lobe designs and matching components are found. That’s why comparing camshafts that at first glance seem to have similar lift and duration numbers just doesn’t tell the whole story.

You owe it to your racing fortunes to look beyond a few general specs, to the hundreds of other critical specifications, measurements and tolerances that make the difference between middle of the pack and victory lane.

It’s 7:30 PM on Friday night; do you know where your camshaft company is?

HOW TO ORDER

HOW TO ORDER COMP Cams® leads the industry in camshaft lobe offerings. With thousands of active lobes in the COMP library, the combinations are infinite for any given engine. That means that you can have a cam ground to your specific needs, and you have the broadest selection of lobes available anywhere.

2. Selecting Lobes

1. 2. 3. 4.

Some lobes specifically designated to be intake or exhaust lobes do not necessarily have to be run on the valve for which they were designed. If an exhaust lobe has the desired spec for intake (or vise versa) they may be used in that manner.

The lobes are listed on pages 8-61 and represent the most current library of lobes offered by COMP Cams®. They are arranged in groups, each of which is unique in its application. Along with each group is a description of each type, which is intended to help clarify each family Choosing a cam for your specific application is a four-step of lobes so that you may accurately select lobes for your application. process: Select a core Select the lobes Select a lobe separation angle Determine the part number and grind number, and order the cam

So, it is in that context that diameter lifters. lobe selection should begin.

3. Choosing Lobe Separation Angle

1. Selecting a Core

Lobe separation angles (the angle in cam degrees Within the parameter of core applications, we have between the intake and exhaust lobe are also referred to fifteen cores that cover many engine applications. They are as “lobe centers”) are very engine combination dependent. In general, a tighter separation (ex. 104°-106°) results in designated as follows: a “peakier” torque curve more suited to stick-shift cars -0 Steel Billet Round Lobe with multiple gear ratios to change between. Wider lobe -5 Flat Tappet (Either Hydraulic or Solid Lifter) separation (ex. 110°-112°) results in a broader, flatter -5RR Reverse Rotation Flat Tappet torque curve that is more suited to automatic transmis-7 Special Flat Tappet sion cars with fewer gears from which to choose. -8 Street Roller (Either Hydraulic or Solid Roller) Therefore, engines have to be more powerful over a Special Material – Bronze Distributor Gear broader rpm range.

These cores must be roughed and then heatground on the core. treated before finished lobe grinding takes place.

The complete core list follows on pages 5-7. The list is separated into the different cam core types. The part number in front of each core is used in ordering a custom ground cam for a particular engine type. It consists of a two-digit prefix designating the engine type, followed by a dash (-) and three consecutive zeros. The zeros indicate a custom ground cam. Next are a dash and number from the core designations previously listed.

4. Determining a Part Number and Grind Number and Ordering

Example: Engine Prefix 12-

Part Number 000

The bottom line is that not all grinds can go on every core that is available. More popular engines, like the Small Block Chevy, have a variety of cores available with varying lobe separation angles that can accommodate almost any grind. Less popular applications, like the Flathead Ford V8, only have one core available. Therefore, they are somewhat limited in terms of what grind will fit on the single existing core.

Core Type -9

With the part number determined in the core selection process, the grind number is the final step prior to orderThe number 12- indicates Small Block Chevy (found on the ing the cam. This process is simple and is accomplished core listing on pages 5-7). by picking up the “lobe number” that appears in the left column of the lobe selection chart. The number 000 indicates a custom grind. The intake lobe will be first and the exhaust lobe will be second, followed by the lobe separation angle.

The -9 indicates steel billet roller core.

HOW TO ORDER

Part #: 12-000-5

HOW TO ORDER

For example, if lobe 5201 is selected as the intake and 5203 is selected as the exhaust, with a 106° lobe separation angle and this configuration is to be ground on a Small Block Chevy core, the full number for ordering that cam would be:

However, if you wanted to order a cam with the same specs for a Big Block Chevy but with 55mm journals and a .812” lifter wheel diameter, your grind number would be:

CB 4314RE/4074RE R110

Grind #: CS 5201/5203-H106

Core Listings Non-Standard Journal Size

Roller Cam Lobe Suffix Codes When it comes to ordering a roller cam, there are two things that need to be considered: journal diameter and roller lifter wheel diameter. Journal size and wheel diameter are very important in making sure the lobe is performing to the specifications you require. For example, if you were selecting lobes for a custom grind Big Block Chevrolet cam then you would need to make sure the lobes were designed for a Big Block Chevrolet journal diameter (1.948”). If Small Block Chevrolet lobes were used instead, the specifications of the cam would be inaccurate. The journal diameter of a Small Block Chevrolet is 1.868”. The lobes on the big block cam would “grow” approximately 2 degrees if ground using small block lobe designs. The same principle applies to various roller lifter wheel diameters. COMP Cams® has done the math for you, so all you need to do is make sure you order the lobes with the right suffixes to signify the correct journal diameter and roller lifter wheel diameter.

remaining part) is removed by machining and a new dowel pin is inserted.

COMP Cams® Special Services A partial listing of the most common high end treatments and special processes you can order for your COMP Cams® camshaft. Additional services are available; contact us for any special needs.

Installation of Dual Dowel Pins - Part #1-121-1

For certain applications, dual dowel pins can be installed to further ensure that the camshaft and timing gear connection are secure. This is most commonly done with early model Ford V8’s and classic Chrysler Hemi engines. We can also machine the timing gear to adapt to this new configuration.

Camshaft Surface Preparations Nitriding - Part #1-111-1

This is the most effective process for extending the life of a high performance flat tappet camshaft. Nitriding increases the hardness of the camshaft surface metal by physically injecting nitrogen “needles” into the surface of the lobes and journals to increase their resistance to wear.

Drilling and Tapping Camshaft Nose Part #1-136-1

A process performed on Viper camshafts, the nose of the camshaft is drilled and then tapped to convert from a single timing gear bolt-up to a three-bolt aftermarket timing chain set. This allows for a wider selection of timing sets.

Camshaft Micropolishing - Part #1-114-1

This procedure removes microscopic imperfections in the surface of the metal. Micropolishing can further increase the durability of the camshaft and can be performed to just the camshaft lobes or all wear surfaces.

Machining a Rear Camshaft Journal Groove Part #1-119-1

A process commonly performed on 1965-‘66 Big Block 396cid Chevrolet engines, which features oiling systems that require a groove be cut into the rear journal of the camshaft. This was a two-year only condition, not required in all 1967 and newer Big Block Chevrolet engines.

Xtreme Surface Finish Enhancement Part #1-137-1

Our highest-quality finishing process involving considerably more polishing than any other procedure. This is most commonly used in steel-on-steel contact valve train situations, such as high end circle track flat tappet camshafts where billet materials have repeated contact in extremely high rpm environments.

Machining of the Rear Pump Drive - Part #1-116-1

Allows sprint cars-style engines to run the fuel pump from the rear of the camshaft rather than traditional placements. Side Cutting of Camshaft Lobes - Part #1-127-1

Precision Camshaft Measurement

A process often requested when the engine’s lifter bores have been enlarged that helps to keep the lifters from making contact with adjacent lobes.

Basic Camshaft Profiling - Part #1-126-1

Performed on two lobes of any camshaft, the component is measured to determine its lift, duration and lobe centerline specifications.

Sleeving of the Camshaft Journal - Part #1-132-1

Most popular with Ford Windsor engine roller bearing camshaft applications, a sleeve is placed around the standard rear journal to increase the size of the journal, making it compatible with rear roller bearing usage.

Adcole Camshaft Profiling - Part #1-125-1

Our highest precision camshaft measuring device, the Adcole checks all 16 camshaft lobes to determine that the cam meets all specifications requested by the customer. The Adcole measures camshaft specifications to 0.00001 of an inch.

Fuel Pump Lobe Regrinding - Part #9-999-1

A refinishing process used to clean up a fuel pump lobe which may have been damaged or is showing excessive wear.

Special Operations Replacement of the Camshaft Dowel Pin Part #1-120-1

This is a process which repairs camshafts where the current dowel pin has either been sheared off or damaged in some manner. The old dowel pin (or

HYDRAULIC FLAT TAPPET

XTREME ENERGY™ HYDRAULICS Designed to maximize torque, acceleration and throttle response while providing excellent high rpm horsepower. A faster intake valve opening increases engine vacuum and enhances throttle response. Special intake closing ramps close the valve sooner, providing more cylinder pressure and torque without resulting in excessive valve train noise. Faster ramps achieve maximum velocity sooner, increasing the area under the lift curve and providing maximum horsepower. Smoother exhaust designs allow for a more effective purge of spent gasses from the combustion chamber to further increase horsepower. LOBE NUMBER

HYDRAULIC FLAT TAPPET

XFI™ HYDRAULICS The XFI™ Series is designed for use with modern induction systems, heads, springs and rockers. The XFI™ intake lobes have more lift than the baseline Xtreme series, and the exhaust lobes have more area under the curve, for better exhaust flow, than the base exhaust series. These are the first hydraulic flat tappet profiles designed for use with COMP Cams® Beehive™ Ovate Valve Springs, such as the #26915, #26918 and #26120. The combination of these profiles, the new springs and our very stiff Pro Magnum Rocker Arms™ in higher ratios, makes for the most revolutionary improvement in hydraulic flat tappet design to date by bringing the latest race winning technology to the street.

CAMSHAFT TYPE

RACE HYDRAULICS These are the largest hydraulic designs that COMP Cams® offers. With a minimum tappet diameter of .842” or larger needed, these designs are intended for all out racing only. The larger lobes (268˚ - 270˚ - 276˚ @ .050” duration) were designed with large cubic inch motors in mind in a high rpm environment. These lobes have smooth ramps, making it easier for the spring to control the valve. LOBE NUMBER

HYDRAULIC ROLLER

HIGH ENERGY™ & MAGNUM HYDRAULIC ROLLERS - LOW & HIGH LIFT The low lift profiles were designed for street and marine use. The low lift adds dependability and reliability for extended use applications. The high lift versions of the hydraulic rollers are designed for all out applications where high lift is desired because of cylinder head or engine modifications. They function well for street and strip. These lobes run well in big cubic inch marine engines.

HYDRAULIC ROLLER XTREME ENERGY™ HYDRAULIC ROLLERS These designs share all of the characteristics of the flat tappet lobes, but we have added the new technology of CRC (Constant Radius of Curvature) inverted radius of curvature ramp designs. COMP Cams® has enhanced this technique to ensure durability with these most aggressive hydraulic roller designs. The high lift versions that have lobe numbers in the 3100's are more aggressive over the nose and will require more spring or less rpm. These lobes run well in street, strip and marine applications. With more agressive and faster ramps, they also provide good vacuum. LOBE NUMBER

XFI™ HYDRAULIC ROLLERS The XFI™ Series is designed for use with modern induction systems, heads, springs and rockers. The XFI™ intake lobes have more lift than the baseline series, and the exhaust lobes have more area under the curve, for better exhaust flow, than the base exhaust series. These are the first hydraulic flat tappet profiles designed for use with COMP Cams® Beehive™ Ovate Valve Springs such as the #26915, #26918 and #26120. The combination of these profiles, the new springs, and our very stiff Pro Magnum Rocker Arms™ in higher ratios, makes for the most revolutionary improvement in hydraulic roller design to date by bringing the latest race winning technology to the street.

XTREME RPM FOR LS1 Designed with Xtreme Energy™ Technology to provide excellent power with the LS1’s enhanced cylinder head design and high rpm performance. These provide outstanding low rpm torque with increased stability when coupled with the LS1’s larger base circle and 1.7:1+ rocker ratios. High lift versions are excellent for use with improved heads, manifolds and the new COMP #26915 and #26918 Beehive™ Valve Springs.

XTREME ENERGY™ XE-R FOR LS1 The XE-R designs are our most aggressive hydraulic roller ramps to date. They are quicker off and on the seat than the original Xtreme Energy™ series, yet they are still stable with rigid valve train and optimized spring selection. These profiles provide even more area than the comparable Small Block Chevrolet designs that are often used by other companies to "grow" a more aggressive lobe for LS1 applications. LOBE NUMBER

SOLID FLAT TAPPET

SOLID FLAT TAPPET HIGH ENERGY™ & MAGNUM SOLIDS The High Energy™ Solid is the mechanical version of the High Energy™ Hydraulic. Because these designs incorporate a mechanical (solid) lifter, the valve actuation is quicker than the High Energy™ Hydraulics, thus producing slightly more power than its hydraulic counterpart. The Magnum Solid Lifter Series is designed to allow the valve lash to be varied from .015” to .030”. This tuning tool can be used to fine tune any high performance application to a razor sharp edge.

XTQ SOLIDS The XTQ Solid design sets the new standard for aggressive .842” lifter designs. With seat timing as low as our original Tight Lash Series and more area than our famous “XX” .875” series, these designs give their racers a clear edge over the competition. Smaller designs are intended for restricted applications; larger designs can be used in open applications with an optimized valve spring selection and lighter valve train. Note: Cams using these lobes should have provisions for increased oiling. Please consult with our tech representative.

XTX SOLIDS The new XTX Solids are an excellent choice for exhaust profiles to be coupled with either the XTQ of MH profiles or can be use for both intake and exhaust in high rpm applications. The closing side is similar to the High Torque profiles, but this design incorporates a faster opening side to increase torque and provide more area. The lifts are slightly less than the High Torque profiles to increase the nose radius and reduce wear. Note: Cams using these lobes should have provisions for increased oiling.

MAX AREA LIFT RULE The Max Area Lift Rule lobes can be run with solid lifters or Pro Magnum™ style hydraulic lifters. They are more aggressive off the seat than the parent Max Area series for tighter lash and less rocker. They work excellent in lift rule oval track, road race and high rpm NHRA Stock Eliminator classes. Will check 21 degrees larger at .006" than .020". Specifically designed to optimize dynamic valve motion and produce maximum power, these lobes use the experience gained from racing the MA profile and the new techniques we learn from our Spintron® testing to provide the best performance in all lift rule applications. Grouped in lobe lift increments for convenient selection. Note: Cams using these lobes should have provisions for increased oiling. Please consult with our tech representative.

MH SOLIDS MH solids are the most aggressive .842" solid lifter profiles available. These are best in restricted applications where maximum torque and power are required and valve train rules are open except for requiring .842" flat tappets. COMP's new #26094 valve spring, 3/8" min. pushrod diameters, Performance Series™ Lightweight Oiling Tappets and Shaft Mounted Rockers are all highly recommended. Please consult with a COMP Cams® CAM HELP® technician or one of our Engine Builder Sales personnel before using these profiles to reduce the risk from improper component selection.

SOLID FLAT TAPPET FL & SQ SOLIDS The FL Series is designed to provide excellent area under the curve with an .875” tappet. These work great in place of TL's where .875" lifters can be used. Excellent in restricted applications with 1.65:1 to 1.75:1 rocker arms. Increased valve spring loads are recommended for higher rpm. The SQ designs are the larger cousins of the FL Series and can be used in higher rpm applications with increased spring loads.

DASH 13 SOLIDS Dash 13 Solids are very similar to both the Dash 12 and XX open designs. These provide a more modern, in-between series that can handle more rocker ratio than either of the two earlier families. Note: Cams using these lobes should have provisions for increased oiling.

CAMSHAFT TYPE

Dash 13 Rated Duration @ .020” Tappet Lift .875" Min. Dia.

F3 EXHAUST SOLIDS The F3 Exhaust Solids are like the Dash 13 high lift lobes, but they have a faster opening ramp ramp design to help increase torque while increasing opening area to reduce pumping losses. Note: Cams using these lobes should have provisions for increased oiling.

XX SERIES SOLIDS The smaller restricted designs are very aggressive. The larger open designs are for continuous high rpm, providing stability over 8500 with good related components. Both require proper spring selection and regular maintenance. Very good horsepower curves. Proper break-in is very critical with these lobe designs. Best when used with COMP Performance Series™ Lightweight Solid Lifters and 1.6 - 1.7 rocker ratios. Note: Cams using these lobes should have provisions for increased oiling.

SOLID FLAT TAPPET

SOLID FLAT TAPPET NRX SOLIDS The NRX Solids are designed for use in Nextel Cup engines with 55mm or larger journals. They are designed with higher lobe lifts than the standard journal families to allow either less ratio or higher lift. Use in applications with less than 55mm journals will result in a small nose radius and premature wear.

HI-TECH™ .420" ROLLERS The Hi-Tech™ .420” is primarily used in oval track racing with good cylinder heads. The ramp designs are easy on valve springs yet produce good power. They are great for long rod motors. They are also popular in bracket and marine applications where power with durability is a must. Also available in Ford Small Block and Chevy Big Block or 50mm sizes to prevent “cam growth” in the grinding process, allowing the engine builder to have more control over the tuning process.

TK SERIES ROLLERS The TK Series is our most aggressive standard rocker ratio series to date. These designs get from .020" to .050" tappet lift and back from .050" to .020" tappet lift in only 28˚. That quickness makes this series the most intense roller profiles COMP has ever released, providing more duration at .200" and more area than comparable profiles. Excellent for all out Sprint Car and Late Model applications. Please consult with a COMP Cams® CAM HELP® Technician or one of our Engine Builder Sales personnel for proper component selection.

JX DRAG RACE EXHAUST ROLLERS The JX Drag Race Exhaust profiles are good complements to either the CE, REV or RX intake designs. They are intended for very large port, high flow cylinder head applications and work well in the high rpm range where Comp Eliminator and similar high rpm small displacement engines operate.

JX Drag Race Exhaust Rated Duration @ .020” Tappet Lift

XCX DRAG RACE EXHAUST ROLLERS The XCX Series rollers provide state-of-the-art ramp designs with the ramp characteristics required to decrease pumping losses and allow exhaust gases from overlap to provide signal to accelerate the intake charge into the cylinder in large port, drag race applications. These modern designs are very stable and respond well to rocker ratio increases.

SOLID ROLLER

SOLID ROLLER XJX EXHAUST DRAG RACE ROLLERS The XJX Drag Race lobes are like the XCX but with higher acceleration rates, more lift, and more area under the curve. The asymetric design with higher opening acceleration helps move more exhaust gas at bottom dead center, reducing losses as the piston comes up, driving the remaining exhaust from the cylinder. These profiles are designed for very stiff valve train systems with 60mm journals and larger, .850" diameter roller lifter heels. LOBE NUMBER
