COMP Cams Camshaft Kit CS XR276HR-12

If you're looking to build a marine engine, especially for a jet boat with an A or B impeller, this COMP Cams Camshaft Kit is a solid choice. This kit is designed to give you strong mid-range power, which is crucial for getting your boat up on plane and maintaining speed. It's specifically intended for Small Block Chevrolet engines from 1987 and newer that came with a factory roller camshaft, excluding LT-1 and LS1 variants. You'll need a good exhaust system to really let this camshaft breathe and perform at its best.

This isn't just a camshaft; it's a complete K-Kit, meaning it includes everything you need to get the job done right. Inside the box, you'll find the camshaft itself, lifters, valve springs, retainers, valve locks, and valve stem seals. COMP Cams also includes a timing chain set to ensure your valvetrain timing is spot on. For flat tappet applications, assembly lube is included, along with decals and detailed instructions to guide you through the installation process. This comprehensive approach means you won't be scrambling to find compatible parts.

This kit is built for performance and reliability, aiming to improve the powerband of your engine, particularly in the mid-range where it matters most for boats. While it's designed for a range of vehicles, including models like the Chevrolet Camaro, Corvette, and various C/K series trucks from the late 80s and 90s, its application is focused on the marine environment for optimal results. Make sure to check the included instructions for specific installation details and any other components that might be recommended for your build.
