COMP Cams® Performance CamshaftsMade In America
camshaftsCamshafts are what COMP Cams® is all about. The cam has long been revered as the "brain" of the engine, opening and closing the valves at the exact precise instant, coordinating the timing of each event to the exact location of the crankshaft and piston. The cam also has the remarkable ability of repeating this process over and over, as many times as necessary, in order to keep the engine running at the peak of its capability. Precise overlap events properly introduce raw fuel and expend exhaust. This provides a highly efficient scavenging process, then repeats the entire process all over again on the next stroke. Even more remarkable, the product we produce at COMP Cams® is a highly modified version of the stock, mass produced camshaft, designed to extract the most performance possible from a given application. High Performance CamshaftHighly trained engineers, and experienced lobe designers work hand in hand producing better, more refined products on a daily basis. Last years product is no longer the standard by which all others are judged. New and better products must be produced to stay ahead of the maximum performance game. In an industry where 2nd place means 1st loser, there is no margin for error. There is no room for 2nd best. This is where COMP Cams® excels, we design and manufacture the winner’s camshafts.

Since day-one, COMP Cams® has sought to produce the best camshafts and valve train components on the market. We have ventured into every imaginable type of racing, designing products for a multitude of engine combinations and variations. We have designed products intended to perform at equal to, as well as less than maximum output, in order to open up venues to enthusiasts who would otherwise be excluded from competition.

In all of this, COMP Cams® has been propelled to the forefront of the automotive performance industry. We are the standard by which performance cam companies are judged. All of this so that our customers have the best selection of product available in the entire performance industry.

In 1977, there was a void in the street performance market. There were few selections available for the street enthusiasts that did not require excessive modifications. The designers at COMP Cams® saw this void and designed cams that worked with stock and near stock components, while maintaining acceptable fuel consumption and streetability. Jobbers and performance warehouses jumped at the opportunity to offer these products to the masses. Terms like Pure Energy, High Energy and Magnum suddenly became the jargon of the day, and COMP Cams® became the fastest growing cam company in the country.
The standards at COMP Cams® have not changed. We are still the leaders of the industry, with the finest Research & Development, Engineering and Quality Control Departments in the performance marketplace. The focus today is still on better products, satisfying the needs and desires of racers from all over the world.

The appearance of the camshaft hasn’t changed much in the last 50 years. What we know about camshafts has far exceeded the expectations of the original designers. Every day we learn more, and everyday we apply this knowledge to the refinement of the performance camshaft.

High Energy™ Cam
These high torque cams work very well on the street. Designed for use in carbureted engines having a 9:1 CR or less. Can be used in conjunction with most stock components, including intake and exhaust manifolds, and carburetors. Normally, gas mileage will either remain the same or increase over a stock cam

240H High Energy™ is ideal for small cubic inch engines that require good low RPM torque.
The 240H cam is a good replacement cam for O.E.M. because no additional valve train components are necessary. This cam works great with computer ignition systems, overdrive transmissions and high gear ratios. The 240H cam provides a very smooth idle, quiet operation and good throttle response. With the 240H cam, you can expect better mileage and a slight power increase over a stock cam.

252H High Energy™ is ideal for medium-sized engines (300-350 c.i.) that require good low speed torque.
This cam is a good “all-around” cam for family sedans and a great performance cam for turbocharged V-6 and V-8 engines. The 252H cam is a good replacement cam for O.E.M. that works with most stock valve train components. It also works with most overdrive transmissions and high gear ratios.

260H High Energy™ is the perfect cam for vans, family sedans, pickups and tow vehicles.
This cam provides exceptional power and a gas mileage increase, especially on the highway. With its great torque and throttle response, the 260H cam can also be used for O.E.M. replacement in most big block applications. The 260H’s idle is smooth in large engines with stock exhaust systems. With headers, the 260H will produce a slight exhaust sound.

268H High Energy™ is our most versatile cam.
It is a great high performance cam for small blocks and a powerful cam for big blocks. With its noticeable idle and great all-around power, the 268H cam is great for daily driven performance vehicles. The 268H cam is an ideal cam for pickup drivers who want major power increases. It is also good for big blocks towing heavy loads equipped with lower optional rear end gears.

Dual Energy™ Cam
These cams have more exhaust duration and lift than intake. Designed for applications where a slight sacrifice in low end is acceptable for an increase in mid and upper range RPM horsepower. They may be used in conjunction with an exhaust system that is much more restrictive than the intake system

255 Dual Energy™ is great for low RPM, high torque applications. It will also give good fuel economy. The 255 will have a smooth idle and will work well in an RV or towing application.

265 Dual Energy™ has good mid range power for mild street performance with a slightly noticeable idle. This cam also works well with a stock torque converter and rear end gears over 3.23:1. The 265 also works well with stock intake and exhaust manifolds.

275 Dual Energy™ is the largest and most aggressive in the Dual Energy™ series. The 275 Dual Energy Cam™ is designed for high performance street driving, yet will work a stock torque converter. The 275 will have a rough idle, but will work with stock exhaust systems.

Magnum™ Cam
These cams are very aggressive, designed for performance oriented vehicles where they will see little street use. Stock components are generally incompatible Changes are needed in rear end gear ratios, headers and the torque converter. Magnum Cams™ are available in two different lifter types:

  • Hydraulic Flat Tappet — Kits are listed with anti-pump up hydraulic lifters. Providing a good compromise between low maintenance requirements and performance capabilities
  • Hydraulic Roller — These have all the abilities of the hydraulic flat tappet cams but when paired with the required roller lifters the lobes are designed to provide higher torque output and a smoother idle for the same RPM range
  • 270H Magnum™ is a great cam for high performance driving in street machines. The 270H has a rough idle in small blocks and a noticeable idle in big blocks. This is the largest cam you can use with a stock torque converter. The 270H will not affect power accessories, but should be used with headers and a 4 BBL. carburetor. This is the perfect cam for cruising.

    280H Magnum™ is best for the more serious street machines. This cam has a definite rough idle and will sometimes affect power accessories. It can be driven extensively on the street or raced on the weekends. The 280H needs an aftermarket torque converter, intake manifolds and headers.

    286H Magnum™ is a design to fill in the gap between the 280H and 292H. Designed for serious street machines and bracket racers. With a rough idle and lower vacuum signal, this is not an average street cam. At least a 2500 RPM converter must be used, but a 3000 is recommended.

    292H Magnum™ is for the serious “Street/Strip” type car. An aftermarket torque converter should be used as well as headers, intake and increased compression. The 292H has a radical rough idle.

    305H Magnum™ should really be considered for Pro-Street type cars where actual streetability is not a major concern. The design of this cam also makes it ideal for all bracket racing engines. Major engine modifications are needed as well as transmission and driveline improvements. The 305H works best in large C.I. engines and has a radical idle. This is the only hydraulic cam in the series that does not have an advance made into it and will need to be degreed in.

    270S Solid Magnum™ is the perfect cam for small to medium cubic inch engines. The 270S delivers good low speed torque with a moderate noticeable idle. This cam is an excellent alternative to the 268H.

    282S Solid Magnum™ is great for street machines because it can be driven daily and raced on weekends. This cam features a broad power curve and torque range with a mild rough idle.

    294S Solid Magnum™ is a maximum performance cam. This cam should be used in high compression 4-speed cars or with a stall speed converter. The 294S makes great top-end power and works well with ported heads.

    306S Solid Magnum™ is an excellent grind for large cubic inch Pro-Street type engines. This cam has tremendous high RPM power and needs to be used with headers, intake and higher compression. An aftermarket torque converter or 4 speed should be used. Radical idle. This cam also does not have the advance made into it and will need to be degreed in.

    268R Roller Cam is the most versatile of all the street roller cams. Excellent throttle response and vacuum makes the 268R an ideal cam for Street Rods, Street Machines and Show Cars with power accessories. The 268R is an excellent all-around cam for the performance minded enthusiast due to its reliability and mileage.

    280R Roller Cam Street/Strip performance or daily usage is possible with the 280R Roller Cam’s broad range of applications. A moderate idle in the higher compression engines makes the 280R a good choice for Street Machines or Street/Strip applications where power and valve train stability are important.

    288R Roller Cam is a proven camshaft that provides great power and reliability. This cam works best with aftermarket manifolds, headers and other performance accessories. Stall speed converters should be used and 4:10 gears or better. A rough idle and moderate vacuum makes the 288R an excellent choice for Serious Street Competition.

    300R Roller Cam is an excellent choice for maximum effort Street Machines with small blocks and 10.5 to 1 or better compression with 3,500 to 4,500 converters. Aftermarket headers and manifolds are good accessories for this cam. Increased horsepower and torque per cubic inch make the 300R a true high performance cam in small and big block applications.
