COMP Cams Camshaft Kit CS XR288H-R10

This is the COMP Cams CS XR288H-R10 hydraulic roller camshaft kit, designed for Chevrolet Gen 1 Small Block engines. It's a complete package aimed at street/strip applications where you want a noticeable change in your engine's personality, often paired with headers and a higher stall torque converter. This kit is built for engines with around a 9:1 compression ratio and will result in a rougher idle, which is typical for cams with these performance intentions.

What makes this kit a solid choice is that it’s a complete system. Instead of sourcing individual components, you get the camshaft, lifters, valve springs, retainers, valve locks, valve stem seals, and even a timing chain set all in one box. This ensures all the parts are designed to work together for optimal performance and reliability. COMP Cams is a well-known name in performance camshafts, and this Xtreme Energy series cam is popular for its aggressive lobe profiles that help your engine breathe better at higher RPMs. The kit also includes assembly lube and decals, making the installation process more straightforward, especially since it's a hydraulic roller setup which generally requires less maintenance than flat tappet cams.

This kit is intended for Chevrolet Small Block engines from 1955 through the early 1980s, and some later models that still use a flat tappet camshaft system. It's important to verify your specific engine block is not a factory roller setup, as GM phased those in starting in the mid-80s. If you're rebuilding the top end of your engine and looking for a significant performance bump for a street/strip car, this kit offers a comprehensive solution. Remember to check the manufacturer's instructions for specific setup details, especially regarding the 1955-1957 265ci engines which may require an oiling groove on the fifth journal.
