COMP Cams Camshaft Kit CS XM 256H-12

This is the COMP Cams Camshaft Kit CS XM 256H-12, designed for Chevrolet Gen 1 Small Block engines. It's a complete package aimed at improving the performance and economy for pleasure boat applications, skiing, and general use. This kit is a solid option if you're looking to rebuild or upgrade the top end of your engine and want a comprehensive set of matched components to get the job done right.

The Xtreme Marine 212/218 hydraulic flat tappet camshaft is at the heart of this kit, offering a good balance for various uses. COMP Cams has bundled everything you need to install it, including lifters, valve springs, retainers, valve locks, valve stem seals, and a timing chain set. They even include assembly lube for flat tappet applications, along with decals and instructions, making it a truly all-in-one solution. This approach ensures that all the parts are designed to work together, which can save you time and guesswork during the installation process.

It's important to note that this kit is intended for engines that use a flat tappet camshaft setup. GM transitioned to roller camshafts in many Small Blocks starting in the mid-80s, so you'll want to confirm your specific engine's configuration before purchasing. This kit fits a wide range of Chevrolet Gen 1 Small Blocks, including popular displacements like the 350, 327, and 400, and is also found in vehicles like the Chevrolet C10, Camaro, and Corvette from certain years. Always refer to the detailed fitment guide to ensure compatibility with your particular vehicle and engine combination.
