COMP Cams Cam & Lifter Kit CS XR282HR-1

If you're building a street machine and looking to get more out of your Chevrolet Small Block Gen 1 engine, this COMP Cams Xtreme Energy hydraulic roller cam and lifter kit is a solid choice. This kit is designed to wake up an engine that's already running well, giving it a noticeable bump in performance. It’s a popular upgrade for those who want a more aggressive feel and sound from their classic Chevy V8.

This kit includes the XR282HR-1 camshaft and a set of hydraulic roller lifters. The camshaft features a 230-degree intake and 236-degree exhaust duration at .050 lift, which is a fairly aggressive profile that will give you a mildly rough idle. To make the most of this cam, you'll need supporting modifications like an upgraded intake manifold, headers, a torque converter with at least a 2500 RPM stall speed, and a suitable gear ratio in your rear end. The kit also comes with assembly lube, decals, and instructions to help you get it installed correctly.

This kit is compatible with a wide range of Chevrolet Gen 1 Small Block engines, including popular displacements like the 350, 400, and 327. It's important to verify that your engine is a flat tappet design and not a factory roller setup from 1985 or newer, as this kit is designed for the earlier flat tappet blocks. If you're unsure, checking the intake manifold or timing cover area can help confirm your engine's configuration. For 1955-1957 265 engines, a specific oiling groove on the 5th cam journal is required.
