COMP Cams Cam & Lifter Kit CS XR264HR-1

If you're looking to get more out of your Chevrolet Gen 1 Small Block engine, this COMP Cams Cam and Lifter Kit is a solid choice. This kit is designed for pleasure boat applications, offering good economy and improved performance for skiing or general use. It's a hydraulic roller setup, which generally means less friction and better durability compared to flat tappet cams.

The XR264HR-1 camshaft features a 212 degrees of intake duration and 218 degrees of exhaust duration at .050 inch lift, with a .488 inch intake lift and .495 inch exhaust lift. These specs are well-suited for a wide range of Chevrolet Gen 1 Small Blocks, including popular displacements like the 350, 400, and even older 283 and 327 engines. It’s important to verify your specific 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 kit comes complete with the camshaft, lifters, assembly lube, decals, and instructions, making the installation process more straightforward.

This kit is a great option for those rebuilding or upgrading their engine, aiming for a noticeable improvement in power and efficiency. Remember to consult the included instructions for proper installation procedures, especially regarding the oiling groove requirement for 1955-1957 265 engines.
