COMP Cams Camshaft Kit CBVI XR288HR-14

This is the COMP Cams XR288HR-14 hydraulic roller camshaft kit, designed for high-performance street and race applications in Chevrolet Big Block Gen VI engines. If you're looking to build a serious performance engine, this kit gives you the core components to significantly improve your engine's breathing and power output. It's a complete package, meaning you get everything you need to get the camshaft installed and running right.

What makes this kit stand out is that it's a K-Kit, which COMP Cams puts together to ensure all the parts work well together. You'll find the camshaft itself, a set of hydraulic roller lifters, valve springs, retainers, valve locks, and valve stem seals. It also includes a timing chain set to ensure your valvetrain stays perfectly synchronized. For flat tappet applications, they even include assembly lube, and you get decals and instructions to guide you through the process. This kit is specifically tuned for computer-controlled engines, offering a 236-degree intake and 242-degree exhaust duration at .050 inch lift, with a .572 inch intake and .565 inch exhaust lift. This profile is best suited for engines that will see a lot of wide-open throttle time and are built for serious power.

To get the most out of this camshaft kit, COMP Cams recommends pairing it with an upgraded intake manifold, headers, a lower gear ratio (like 3.73 or numerically higher), a torque converter with a stall speed of 2600 RPM or more, and an engine programmer to fine-tune the fuel and ignition timing. This setup is intended for engines that will be pushed hard, whether on the street or at the track. Please note that this part is not CARB approved and cannot be shipped to California.
