COMP Cams Cam & Lifter Kit CS XR258HR-1

When you open this box, you'll find a COMP Cams Cam & Lifter Kit, specifically the CS XR258HR-1. Inside, you'll get the camshaft itself, a set of lifters, assembly lube to help with the installation, decals, and the manufacturer's instructions. This kit is designed for Chevrolet Gen 1 Small Block engines, offering strong torque and good mileage, making it a solid choice for engines that are stock or have mild modifications.

This hydraulic roller camshaft kit is built to provide a noticeable improvement in performance for a wide range of Chevrolet vehicles. It's engineered to work with engines like the 262, 283, 305, 350, and 400 cubic inch displacements, among others. COMP Cams has a reputation for well-built performance parts, and this kit is no exception, aiming to give you that extra bit of power and efficiency you're looking for without going overboard.

It's important to confirm your engine's configuration before installation. This kit is for flat tappet camshaft blocks. If your engine was built from 1985 or newer and has a factory roller camshaft, this kit will not fit. You may need to remove the intake manifold or timing cover to verify your block type. Also, note that early 1955-1957 Chevrolet 265 engines require a specific oiling groove on the 5th cam journal; contact COMP Cams for details if this applies to your build.
