Product Details

Starting with a 240/246 degree intake/exhaust duration at .050 lift, this COMP Cams Xtreme Energy camshaft kit is built for street/strip applications. It's designed for Chevrolet Big Block engines originally equipped with flat tappet camshafts, like those found in many 1967-1976 models such as the Chevrolet Impala or Chevelle. This kit aims to give your engine a noticeable bump in performance, especially when paired with a 2800+ stall torque converter and a compression ratio of 9.5:1 or higher. Expect a rougher idle characteristic that lets you know this cam means business.

This SK-Kit comes with everything you need to get the job done: the camshaft itself, a set of lifters, a complete timing chain set, assembly lube to ensure proper break-in, and decals. The hydraulic flat tappet design is a popular choice for those looking to upgrade from their stock camshaft without needing to change valve springs or pushrods, provided your existing components are in good condition. It's a well-built package designed to work together for improved engine breathing and power output.

This kit is intended for performance builds and is not CARB approved, meaning it cannot be shipped to California. Ensure your engine's compression ratio and torque converter are suitable for this camshaft's aggressive profile to get the most out of it.
