COMP Cams Cam & Lifter Kit CS XR260HR-1

If you're looking to wake up the performance of your 1987 and newer Chevrolet Small Block engine that came with a factory roller camshaft, this COMP Cams Cam and Lifter Kit is a solid option. This kit is designed to give your engine a noticeable boost in power, especially in the mid-range and upper RPMs, making it a popular choice for trucks and muscle cars looking for improved acceleration and a more aggressive engine note. It’s a complete package to get you started on a significant engine upgrade.

Inside this kit, you'll find the XR260HR-1 camshaft, which features a hydraulic roller design. This means it’s built for smoother operation and better performance compared to flat tappet cams, and it’s compatible with your OE roller lifters. The camshaft specifications are tailored for a good balance of street drivability and performance, with a 210/214 degree intake/exhaust duration at .050 lift. This profile is well-suited for applications like the Chevrolet Camaro, Corvette, or C/K series trucks from the late 80s and early 90s, providing a strong powerband without requiring extensive modifications to the valvetrain or fuel system. The kit also includes a set of compatible lifters to ensure proper valvetrain geometry and function, along with assembly lube to get everything installed correctly and protect your new components during initial startup.

When undertaking a camshaft upgrade, it's important to ensure your engine is in good mechanical condition. This kit is designed for engines originally equipped with a factory roller camshaft, so it will work with your existing lifters if they are in good shape. You'll also want to consider checking your valve springs to make sure they can handle the new camshaft's profile. COMP Cams includes detailed instructions and decals with the kit, helping you through the installation process. Remember, this kit is not CARB approved and cannot be shipped to California.
