COMP Cams Cam & Lifter Kit CS XR286

If you're looking to get more out of your Chevrolet Small Block engine, this COMP Cams Xtreme Energy XR286 Solid Roller Cam and Lifter Kit is a solid choice. This kit is designed for performance builds, especially those running a 3000+ RPM stall torque converter and lower gear ratios. It's a popular upgrade for weekend warriors who want to feel a significant difference in their engine's power band.

This kit includes a camshaft, lifters, assembly lube, decals, and instructions, so you have the essential components to get started. The XR286 camshaft features a 248-degree intake and 254-degree exhaust duration at .050 inch lift, with .572 inch intake and .565 inch exhaust lift. These specifications are tuned for improved performance, but they do require a well-breathing engine to match. Make sure your intake and exhaust systems are up to the task to fully benefit from this cam's potential.

It's important to verify your specific engine's configuration before installation. This kit fits many Chevrolet Gen 1 Small Blocks, including popular displacements like the 350, 400, and 327. However, it does not fit factory roller camshaft engines (typically 1985 and newer 305s and 350s) or the LS-based engines. For 1955-1957 Chevrolet 265 engines, a groove on the 5th cam journal is required for proper oiling. Always refer to the included instructions and consult with a professional if you're unsure about fitment or installation.
