COMP Cams Camshaft Kit CS XR258HR-10

When you're looking to get more out of your Chevrolet Small Block V8, this kit from COMP Cams is a solid choice. What you get in this SK-Kit is everything you need to get started: the camshaft itself, a set of lifters, a complete timing chain set, assembly lube to make the install smoother, and even some decals and instructions. This particular camshaft, the XR258HR-10, is designed for those who want strong torque and good mileage, making it a great option for engines that are stock or have mild modifications.

This kit is built for the classic Chevrolet GEN 1 Small Block engines, covering a wide range of displacements from the 262 all the way up to the 400. It's important to note that this kit is intended for engines with flat tappet camshafts. If your engine was built from 1985 or newer, especially in performance models like Camaros and Corvettes, it might have come from the factory with a roller camshaft. To be sure, you'll need to check your block or timing cover to confirm if it's a factory roller setup. This kit is not compatible with the modern LS-based engines like the LS1, LS2, or the 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L variants.

COMP Cams is a well-known name in performance engine parts, and this kit reflects their focus on delivering improved performance. The Xtreme Energy series is popular for its ability to provide a noticeable bump in torque and overall engine response without sacrificing too much drivability or fuel economy. This makes it a versatile upgrade for a variety of Chevrolet vehicles, from classic muscle cars to trucks and even some commercial applications.
