COMP Cams Cam & Lifter Kit CB XR270H-R1

This COMP Cams Cam and Lifter Kit CB XR270H-R1 gives you everything you need to get a new hydraulic roller camshaft and lifters installed in your Chevrolet Big Block engine. Inside this kit, you'll find the XR270H-R1 camshaft itself, a set of compatible hydraulic roller lifters, assembly lube to get everything started right, and decals for your engine bay. This kit is specifically designed for Chevrolet Big Block engines originally equipped with flat tappet camshafts, covering a wide range of vehicles like the Chevrolet Impala, Chevelle, Camaro, and Corvette from the late 60s through the mid-70s, as well as many truck and van applications.

The XR270H-R1 camshaft features a 218-degree intake and 224-degree exhaust duration at .050 inch lift, with a .550 inch lift on both intake and exhaust. This profile is a popular choice for pleasure boats, offering a good idle quality while still providing a noticeable improvement in power. The hydraulic roller design means less friction and wear compared to flat tappet setups, contributing to better performance and longevity. COMP Cams is well-known for its performance engine components, and this kit is built to their standards for reliability and performance.

When installing a new camshaft and lifter kit, it's important to follow the included instructions carefully, especially regarding the break-in procedure for the new lifters. This kit is intended for use in inboard/outboard pleasure boats and is not CARB approved, meaning it cannot be shipped to California. Make sure to check the fitment details to confirm it's the right choice for your specific Chevrolet Big Block application.
