COMP Cams Camshaft Kit CB XM288H-12

This is the COMP Cams Xtreme Marine Camshaft Kit, part number K11-244-4, designed for Chevrolet Big Block 396-454 engines that originally came with flat tappet camshafts. If you're looking to significantly improve the performance of your classic muscle car, truck, or even a boat with a compatible engine, this kit offers a comprehensive solution to upgrade your valvetrain.

This kit is built around the XM288H-12 camshaft, which features a 244/254 degree duration at .050 inch lift. This means it's designed for aggressive performance use, requiring at least 9.5:1 compression and headers to breathe properly. The kit is well-built and includes everything you need for a complete valvetrain overhaul: the camshaft itself, hydraulic flat tappet lifters, valve springs, retainers, valve locks, valve stem seals, a timing chain set, and even assembly lube. COMP Cams is a well-known name in performance engine building, and this kit reflects their expertise in creating parts that work together seamlessly for optimal results.

When installing this kit, remember that it's intended for performance applications and may require other supporting modifications like headers and a proper ignition setup to get the most out of it. It's important to note that this kit is not CARB approved and cannot be shipped to California. Always refer to the included instructions for proper installation and break-in procedures to ensure the longevity and performance of your new valvetrain.
