COMP Cams Camshaft Kit CS XR252HR-10

This COMP Cams Xtreme Energy camshaft kit is designed for Chevrolet Gen 1 Small Block engines. It's a comprehensive package aimed at improving your engine's breathing and power output. If you're looking to rebuild the top end of your classic Chevy, this kit offers a well-built camshaft and the essential supporting components to get the job done right.

Inside this kit, you'll find the CS XR252HR-10 hydraulic roller camshaft, a set of lifters, and a timing chain set. This combination is engineered to work together, providing a noticeable improvement in throttle response and overall power. The camshaft features a 200/206 degree intake/exhaust duration at .050 lift, which is a popular choice for street performance applications that still need to idle smoothly. It's important to confirm your specific engine is a flat tappet design, as this kit is not compatible with factory roller blocks from 1985 and newer, or LT1/LT4 engines. For 1955-1957 265 engines, ensure there's a groove on the 5th cam journal for proper oiling.

This kit includes assembly lube and decals to help with installation. While this kit is designed for a wide range of Chevrolet Gen 1 Small Blocks, including popular engines like the 350, 327, and 400, always verify your engine's specific configuration before ordering. This is a significant upgrade for your engine, and COMP Cams is a well-known name in performance camshafts.
