COMP Cams Camshaft Kit CS XR276HR-12

If you're looking to get more out of your Chevrolet Small Block Gen 1 engine, especially in a marine application like a jet boat with an A impeller, this COMP Cams Camshaft Kit is a solid choice. This kit is designed to give you strong mid-range power, making it ideal for applications where you need good acceleration and pulling power. To really make this camshaft shine, you'll want to ensure you have a good exhaust system to let the engine breathe freely.

This isn't just a camshaft; it's a complete kit to ensure a proper installation and optimal performance. Inside, you'll find the XR276HR-12 hydraulic roller camshaft itself, along with matching lifters, valve springs, retainers, and valve locks. It also includes valve stem seals, a timing chain set for accurate valve timing, and assembly lube to get everything started smoothly. COMP Cams even includes decals and instructions to guide you through the process.

This kit is built for Chevrolet Small Block Gen 1 engines, covering a wide range of displacements from 262ci up to 400ci. It's important to note that this kit is for engines with a flat tappet camshaft setup. If your engine was built from 1985 or newer and came with a factory roller camshaft, or if it's an LT1/LT4 or LS-based engine, this kit won't be compatible. You may need to remove the intake or timing cover to confirm your block's configuration. For 1955-1957 Chevrolet 265 engines, a specific oiling groove on the 5th cam journal is required.
