Product Details
This COMP Cams Xtreme Energy camshaft is designed for Chevrolet Small Block engines, specifically for high-performance street applications. It's built to work with 100-150 horsepower nitrous kits or small blowers, aiming to give you a noticeable boost in torque, acceleration, and throttle response. You'll get improved high-RPM horsepower thanks to its advanced lobe designs.
The camshaft features a faster intake valve opening to increase engine vacuum and sharpen throttle response. Its intake closing ramps are designed to close the valve sooner, which helps build more cylinder pressure and torque without making the valvetrain excessively noisy. The exhaust lobe profiles are smoother, aiding in the efficient removal of spent gases to further increase horsepower. This camshaft is suitable for use with either carbureted or tunable fuel injection setups.
This camshaft fits a wide range of Chevrolet Small Block engines from 1958 to 2002, including popular displacements like the 350 and 400 cubic inch V8s. It's important to note that this camshaft is intended for engines using hydraulic flat tappet lifters and does not fit factory roller camshaft blocks from 1985 and newer, nor does it fit LT1/LT4 or LS-based engines. Always confirm your engine's lifter type before installation.
