COMP Cams Camshaft Kit CS 268XFI HR-13

When you're looking to wake up the performance of your Chevrolet Small Block Gen 1 engine, this kit from COMP Cams gives you the core components you need. Inside this SK-Kit, you'll find the CS 268XFI HR-13 hydraulic roller camshaft, a set of lifters, and a timing chain set. It also includes assembly lube to help with installation and decals for your engine bay. This kit is designed to provide ample low-end torque with a very good mid-range pull, making it a popular choice for street performance builds.

The XFI 218/224 camshaft is a hydraulic roller design, which generally offers better performance and durability than older flat-tappet designs. The specs indicate a 218 degrees of intake duration and 224 degrees of exhaust duration at 0.050 inch lift, with a lobe separation angle of 113 degrees. This camshaft is noted as being the largest option that can work with a stock torque converter, though an exhaust upgrade is recommended to help the engine breathe better. 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, nor is it for LS-based engines.

This kit fits a wide range of Chevrolet Gen 1 Small Block engines, including popular displacements like the 305, 327, 350, and 400. It's a solid option for those looking to enhance their classic muscle car or truck. Remember to check your specific engine block for compatibility, especially if it's from the mid-80s or later, as GM transitioned to roller camshafts gradually. For 1955-1957 Chevrolet 265 engines, ensure the 5th cam journal has an oiling groove.
