COMP Cams Camshaft Kit CS XR258HR-10

If you're looking to get more torque out of your Chevrolet Small Block GEN 1 engine, this Xtreme Energy Camshaft Kit from COMP Cams is a solid option. This kit is designed to work well with stock to mildly modified combinations, offering strong torque gains without sacrificing too much in terms of drivability or mileage. It's a popular choice for builders who want a noticeable improvement in their engine's performance.

This is a complete K-Kit, meaning it includes everything you need to get the camshaft installed and running right. You'll find the camshaft itself, a set of hydraulic roller lifters, valve springs, retainers, valve locks, and valve stem seals. It also comes with a timing chain set to ensure your valvetrain is perfectly synchronized. For flat tappet applications, assembly lube is included, along with decals and detailed instructions to guide you through the process. This comprehensive approach helps ensure a smooth installation and optimal performance from the start.

This kit is specifically for Chevrolet GEN 1 Small Blocks, covering a wide range of displacements from 262ci up to 400ci. It's important to note that this kit is designed for engines that originally used a flat tappet camshaft. If your engine was factory-equipped with a roller camshaft (typically from 1985 and newer in many models, though some trucks and SUVs went later), you'll need to confirm your block's configuration before ordering. This kit will not fit LT1/LT4 engines or any LS-based engines.
