COMP Cams Camshaft Kit CB XR288HR-10

This COMP Cams kit gives you everything you need to upgrade your Chevrolet Big Block engine to a hydraulic roller camshaft. Inside this kit, you'll find the XR288HR-10 camshaft itself, a set of lifters designed to work with it, a new timing chain set for proper synchronization, assembly lube to get everything started smoothly, and even some decals and instructions to guide you through the process. This is a popular choice for street/strip applications, especially in larger cubic inch engines where you're looking for a noticeable bump in performance, typically paired with a torque converter that stalls around 2500 RPM or higher.

The XR288HR-10 camshaft features a 236-degree intake duration and a 242-degree exhaust duration at .050 inch lift, with a 110-degree lobe separation angle. This profile is well-suited for street machines that see occasional track use, offering a strong powerband that pulls well through the upper RPM range. It's designed to replace older flat tappet camshafts, providing the benefits of roller lifters like reduced friction and increased durability. This kit is intended for Chevrolet Big Block engines like the 396, 427, and 454 cubic inch displacements.

This kit is a solid option for builders looking to get more out of their classic Chevrolet or GM muscle car. It fits a wide range of vehicles, including popular models like the Chevrolet Impala, Chevelle, and Corvette from the late 60s through the mid-70s, as well as many truck applications from the same era. Remember to consult the included instructions for the best installation practices and to ensure all components are properly seated and lubricated before firing up your engine.
