  • Xtreme Energy™ Cams are 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.

  • For Carb or Tunable Fuel Injection3


1: Cams for '55-'57 engines can be custom ordered. Please Call, Email, Twitter or Live Chat for details.

2: The '87+ Chevy Small Block received provisions for roller lifters. Most '87 - '93 GM cars came with roller lifters, but most '87 - '95 trucks came with flat tappet lifters in roller lifter style blocks. If a roller cam is desired and your block has OEM-style roller cam provisions. COMP Hyd. Roller Lifter Install Kit for '87-'90 Blocks or '91-'02 Blocks can be purchased, as well as a '87+ OE-Style Hyd. Roller Cam and '87+ OE-Style Roller Lifters. Roller cam conversion in pre-'87 blocks requires Retro-Fit Hyd. Roller Cam and Retro-Fit Link Bar Lifters.

3: Many OEM EFI systems cannot be tuned to run well with certain cams. Before installing in an OEM EFI engine be sure to check with a competent tuner.
