COMP Cams Camshaft Kit CS XR294HR-10

If you're looking to wake up a Chevrolet Gen 1 Small Block engine for street or strip use, this COMP Cams Xtreme Energy camshaft kit is a solid option. This kit is designed for engines with around 9.5:1 compression, paired with intake and headers, and a torque converter with a 3000+ RPM stall speed, along with appropriate gearing. Expect a noticeable change in your engine's character, including a rougher idle that signals its performance intent.

This kit includes the CS XR294HR-10 hydraulic roller camshaft, a set of lifters, and a timing chain set, along with assembly lube and decals to help with installation. The camshaft itself features a 242-degree intake duration and 248-degree exhaust duration at .050 inch lift, with a .574 inch intake lift and .574 inch exhaust lift. This profile is well-suited for applications where you want significant power gains, particularly in the mid-to-upper RPM range, while still maintaining reasonable street manners for a performance camshaft. It’s important to verify 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.

This kit is intended for a wide range of Chevrolet Gen 1 Small Block engines, covering displacements from 262 all the way up to 400 cubic inches. Examples of vehicles that can utilize this kit include the Chevrolet Camaro, Corvette, Caprice, and various C/K series trucks and SUVs from the 1980s and early 1990s. Always consult the detailed fitment notes to ensure compatibility with your specific application, especially regarding early 265ci engines and the transition to roller camshafts in later models.
