COMP Cams Cam & Lifter Kit CS XR280

If you're building a street machine that needs a serious performance boost from its Chevrolet Small Block Gen 1 engine, this COMP Cams Cam & Lifter Kit is designed to get you there. This kit is specifically tuned for engines running 2800+ stall torque converters, 10:1 or higher compression ratios, and rear gears in the 3.73 to 3.90 range. It's a comprehensive package aimed at unlocking more power and responsiveness for your build.

The Xtreme Energy CS XR280 camshaft is a solid roller design, which allows for more aggressive valve lift and duration compared to flat tappet cams. This translates to better airflow and more power, especially at higher RPMs. The kit includes the camshaft itself, a set of matching lifters engineered to work with the cam profile, assembly lube to ensure proper break-in, and decals for your engine bay. It’s a well-built package that COMP Cams has put together to simplify the process of upgrading your engine's valvetrain.

It's important to confirm your specific Chevrolet Small Block is compatible. This kit fits Gen 1 Small Blocks like the 262 through 400 cubic inch engines, but it does not fit factory roller blocks (typically 1985 and newer, though some trucks and SUVs used flat tappets into the mid-90s) or LS-based engines. If you're unsure, checking your engine's intake or timing cover area will reveal if it's a factory roller or flat tappet setup. For 1955-1957 Chevrolet 265 engines, ensure the 5th cam journal has an oiling groove.
