COMP Cams Camshaft CS XM 276HR-12

Fits '58-'02 262-400 c.i.d. Chevy Small BlocksGood for jet with A impeller - Strong mid-range power - Needs good exhaustXtreme Marineâ„¢ -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.WARNING: Camshaft Optimized for use with a Melanized or Nitrided distributor Gear. Not compatible with cast or Steel Gears without similar surface treatments. Failure to utilize the proper distributor Gear will void all warranties and/or return policies. 1: Cams for '55-'57 engines can be custom ordered. 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 Hydraulic Roller Lifter Install Kit for '91-'02 Blocks can be purchased. As well as a '87+ OE-Style COMP Hydraulic Roller Cam.
