COMP Cams Camshaft Kit CS XR270HR-12

This COMP Cams camshaft kit features a hydraulic roller camshaft with a 218-degree intake and 224-degree exhaust duration at .050 lift. This specific grind is designed for Chevrolet Gen 1 Small Block engines, offering a noticeable idle and good mid-range power with excellent throttle response, making it a popular choice for marine applications and performance street builds. It’s important to confirm your engine is a flat tappet block, as this kit is not compatible with factory roller blocks from 1985 and newer, or LS-based engines.

The SK-Kit includes everything you need to get started: the camshaft itself, a set of hydraulic roller lifters, a complete timing chain set, assembly lube, and decals. This comprehensive package simplifies the installation process, ensuring you have the essential components for a successful engine build. The camshaft’s design aims to provide a significant improvement in the engine's breathing and powerband, particularly in the mid-RPM range where many street-driven vehicles operate.

When installing this kit, pay close attention to the vehicle fitment notes. Early 1955-1957 Chevrolet 265 engines may require a specific oiling groove on the fifth cam journal. This kit is intended for a wide range of Chevrolet Gen 1 Small Blocks, including popular displacements like the 350, 327, and 400 cubic inch engines. Always refer to the included instructions for detailed installation procedures and any specific requirements for your engine combination.
