COMP Cams Camshaft Kit CB XR284H-R12

This COMP Cams camshaft kit is built around the XR284H-R12 hydraulic roller camshaft, featuring a 230/236 degree intake/exhaust duration at .050 lift. This specific grind is designed for Chevrolet Big Block engines originally equipped with flat tappet camshafts, such as the 396, 427, and 454 cubic inch V8s. It’s a popular choice for jet boat applications with an A impeller, offering good performance for pleasure cruising or mild performance builds.

The SK-KIT includes everything you need to get this camshaft installed and running smoothly. You’ll find the camshaft itself, a set of hydraulic roller lifters to match, a complete timing chain set for accurate valve timing, assembly lube to protect the components during initial startup, and even some decals and instructions to guide you through the process. This comprehensive package helps ensure a proper installation and helps protect your new valvetrain components.

This kit is well-suited for a wide range of Chevrolet vehicles from the late 1960s through the mid-1990s, including models like the Chevrolet Impala, Chevelle, and C10 pickup trucks, when equipped with the appropriate Big Block engine. While it offers improved performance for pleasure use, it's important to note that this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's instructions for detailed installation procedures and break-in requirements.
