COMP Cams Camshaft Kit CS XR282H-R10

This COMP Cams Xtreme Energy CS XR282H-R10 hydraulic roller camshaft kit is built for Chevrolet Small Block engines. It's designed for street machines that are looking for a significant step up in performance, and it works well with a range of engine displacements from 262 up to 400 cubic inches. You'll need supporting modifications like an upgraded intake manifold, headers, a torque converter with at least a 2500 RPM stall speed, and appropriate rear-end gearing to get the most out of this cam. Expect a mildly rough idle, which is characteristic of a performance camshaft like this.

This is a complete K-Kit, meaning it includes everything you need to get the camshaft installed. You'll find the camshaft itself, hydraulic roller lifters, valve springs, retainers, valve locks, and valve stem seals. It also comes with a timing chain set to ensure your engine's timing is spot on, plus assembly lube for flat tappet applications, decals, and detailed instructions. This comprehensive package helps ensure a smooth installation process and that all the necessary components work together correctly.

It's important to verify your engine's configuration before installation. This kit is intended for GEN 1 Small Blocks and does not fit LT1/LT4 engines or factory roller Small Blocks from 1985 and newer. GM vehicles gradually adopted roller camshafts starting in the mid-80s, so you may need to remove the intake manifold or timing cover to confirm if your block uses a flat tappet or roller setup. This kit also does not fit any LS-based engines. For 1955-1957 Chevrolet 265 engines, a specific oiling groove on the 5th cam journal is required; please contact us for details if this applies to your engine.
