  • For Retro-Fit (Link Bar) Hydraulic Roller Lifters; Fits '58-'021 262-400 cid Chevy Small Blocks2

  • High performance street machines • 2000+ stall, gears • Choppy idle

  • 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. Feature CRC (Constant Radius of Curvature) technology that ensures durability with aggressive hydraulic roller designs.

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 your block has '87+ OEM-style roller cam provisions but does not have roller components fitted, COMP Hyd. Roller Lifter Install Kit for '87-'90 Blocks or '91-'02 Blocks can be purchased. As well as a '87+ OE-Style COMP Hyd. Roller Cam and '87+ OE-Style COMP Roller Lifters. Pre-'87 blocks require Retro-Fit Link Bar Roller Lifters.
