Product Details

This COMP Cams camshaft kit is built around a hydraulic flat tappet camshaft with a 250/264 duration split, specifically tuned for nitrous applications. It's designed for Chevrolet Big Block engines, covering displacements from 396 to 454 cubic inches, and is intended for use with an 871 blower. For this kit to perform as intended, you'll need to pair it with good cylinder heads, an appropriate intake manifold, and suitable rear-end gears, along with a torque converter rated for 3500 RPM or higher.

The SK-Kit includes everything you need to get started: the camshaft itself, a set of lifters, a complete timing chain set, assembly lube to ensure proper break-in, and decals. This is a race-only package, meaning it's not street-legal and requires a dedicated setup to unlock its full potential. It's a well-built option for those looking to significantly boost the power output of their Big Block Chevy, especially when adding a supercharger and nitrous.

This kit fits a wide range of Chevrolet vehicles originally equipped with flat tappet camshafts, including popular models like the 1967-1975 Chevrolet Bel Air, 1967-1972 Chevrolet Camaro, and 1967-1974 Chevrolet Corvette. Always refer to the included instructions for the most accurate installation details and to ensure all supporting modifications are correctly implemented.
