Description

Fits '58-'02 262-400 c.i.d. Chevy Small Blocks
Pro Street Applications - Excellent for multi-stage nitrous or 671 blower - 2800+ stall
Xtreme Energyâ„¢ 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. 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 Hydraulic Roller Lifter Install Kit for '87-'90 Blocks or '91-'02 Blocks can be purchased, as well as a '87+ OE-Style Hydraulic Roller Cam.
