COMP Cams Camshaft CS XR282HR-10

This COMP Cams Xtreme Energy camshaft kit includes the camshaft itself, designed to fit a wide range of Chevrolet Gen 1 Small Block engines. It's a hydraulic roller camshaft, meaning it uses roller lifters to reduce friction and wear compared to flat tappet designs. This particular grind, the XR282HR-10, offers a 230-degree intake and 236-degree exhaust duration at .050 inch lift, aiming for strong torque and improved response.

COMP Cams developed the Xtreme Energy line to bridge the gap between mild street cams and aggressive race-only grinds. This camshaft is engineered to provide increased torque, better throttle response, and more power while still maintaining a relatively quiet valve train operation and the durability needed for daily driven vehicles. For optimal performance with this camshaft, you'll typically need supporting modifications such as an upgraded intake manifold, headers, a torque converter with at least a 2500 RPM stall speed, and appropriate rear axle gearing. Expect a mildly rough idle, which is characteristic of cams designed for increased performance.

It's important to confirm your specific engine block is a flat tappet design, as this camshaft is not compatible with factory roller small blocks from 1985 and newer, or LS-based engines. Early 1955-1957 Chevrolet 265 engines may also require a specific oiling groove on the fifth cam journal. Always refer to the manufacturer's installation instructions for detailed guidance on proper setup and any additional components required for your build.
