Product Details

COMP Cams is well-known for performance engine components, and their Xtreme Energy line is a popular choice for enthusiasts looking to get more out of their engines. This SK-Kit, specifically the XR300HR-14 model, is designed for Chevrolet Big Block GEN VI engines, offering an updated camshaft profile for improved performance. It’s a great option for larger displacement engines and is particularly suited for bracket racing applications, though it will require a torque converter with a 3500+ stall speed to perform at its best.

This kit comes with everything you need to get the camshaft installed and running smoothly. You'll find the camshaft itself, a set of hydraulic roller lifters, a complete timing chain set, assembly lube to ensure proper initial lubrication, and decals. The camshaft features a 248-degree intake duration and a 254-degree exhaust duration at .050 inch lift, with a .554 inch intake lift and .562 inch exhaust lift, making it a solid choice for building a powerful engine. It’s designed to work well with larger cubic inch engines, aiming to provide a noticeable difference in power delivery for racing or high-performance street use.

This camshaft kit is compatible with a range of Chevrolet and GMC trucks and vans from the mid-to-late 1990s, including models like the Chevrolet C2500 Suburban, GMC Savana 3500, and Chevrolet Express 3500. While this kit is designed for performance, please note that it is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's instructions for proper installation and break-in procedures.
