COMP Cams Cam & Lifter Kit CS XR270HR-1

COMP Cams is well-known for performance engine components, and this XR270HR-1 hydraulic roller camshaft and lifter kit is a prime example of their expertise. Designed for Chevrolet Small Block Gen 1 engines, this kit is built to give you a noticeable idle and improved mid-range power with excellent throttle response. It's a popular choice for builders looking to get more out of their classic V8, whether it's in a truck, muscle car, or even marine applications like inboard/outboard setups.

This kit includes the camshaft itself, a set of hydraulic roller lifters, assembly lube to get everything started right, and decals. The camshaft features a 218-degree intake and 224-degree exhaust duration at .050 lift, making it one of the larger options for marine use while still providing a strong mid-range pull. It's important to verify your engine has a flat tappet block, as this kit is not designed for factory roller blocks from 1985 and newer, or for LS-based engines. Removing the intake or timing cover is the best way to confirm your block's configuration.

For early 265 cubic inch engines from 1955-1957, ensure there's a groove on the fifth cam journal for proper oiling. This kit is a solid option for anyone rebuilding or upgrading their Gen 1 Small Block Chevy, offering a significant change in performance characteristics.
