COMP Cams Camshaft Kit CB XR286 R-10

This COMP Cams Xtreme Energy XR286 R-10 solid roller camshaft kit is built around a camshaft with 248 degrees of intake duration and 254 degrees of exhaust duration at .050 inch lift. This kit is specifically designed for Chevrolet Big Block engines originally equipped with flat tappet camshafts, like those found in models such as the Chevrolet Impala, Chevelle, and Corvette from the late 1960s through the mid-1970s. It’s a comprehensive package aimed at significantly improving your engine’s performance, particularly for weekend warrior applications that see regular use and are paired with a 3000+ RPM stall torque converter.

To get the most out of this solid roller camshaft, it requires a well-matched intake and exhaust system, along with low rear-end gears to effectively utilize the increased powerband. The kit itself is very complete, including the camshaft, solid roller lifters, valve springs, retainers, valve locks, and valve stem seals. You also get a timing chain set, assembly lube for the flat tappet components, and decals. This ensures you have nearly everything needed to perform a thorough camshaft upgrade, making the installation process smoother.

This is a serious upgrade for performance-minded builders. For optimal results, ensure your engine has a robust cooling system and consider the supporting modifications like a high-flow fuel system and ignition. This kit is intended for off-road use and is not CARB approved, meaning it cannot be legally shipped to California.
