COMP Cams Camshaft Kit CS XR258HR-12

When you're looking to get more out of your 305 or 350 small block Chevy, this kit from COMP Cams is a solid option. It includes the CS XR258HR-12 hydraulic roller camshaft, a set of lifters, a timing chain set, assembly lube, decals, and instructions. This kit is designed for engines with factory roller camshafts, commonly found in vehicles like the Chevrolet Camaro, Corvette, and C1500 trucks from 1987 and later.

The XE computer-controlled camshaft profile in this kit offers a good balance of economy and power for street applications. With intake and exhaust duration figures of 206 and 212 degrees respectively at .050 lift, it provides improved throttle response and a noticeable power increase over stock, while still maintaining decent drivability. The hydraulic roller design means less friction and more efficient operation compared to flat tappet cams. COMP Cams is a well-known name in performance engine parts, and this kit is put together to make the installation process smoother by including the essential components you'll need.

This kit is intended for engines that originally came with a factory roller camshaft, so it's important to confirm your engine's configuration. It's not compatible with LT-1 or LS1 style engines. While this kit is designed to improve performance and economy, it is not CARB approved and cannot be shipped to California. Always refer to the included instructions for proper installation and break-in procedures.
