COMP Cams Camshaft Kit CS XR300HR-10

This COMP Cams Xtreme Energy camshaft kit is built around a hydraulic roller camshaft featuring a 248-degree intake and 254-degree exhaust duration. This design is intended for engines with a 10:1 or higher compression ratio, a 3500+ RPM stall speed torque converter, and that utilize good intake manifolds and headers. It's a popular choice for pro street builds and bracket racing applications where consistent power delivery is key.

The kit includes everything you need to get started: the camshaft itself, a set of hydraulic roller lifters, a complete timing chain set for precise valve timing, and assembly lube to ensure proper break-in. COMP Cams is well-known for its performance camshafts, and this Xtreme Energy series is designed to give your engine a noticeable power increase, particularly in the mid-to-upper RPM range. This kit is designed to fit a wide range of General Motors small block V8 engines from 1987 and newer that came factory-equipped with a roller camshaft, such as those found in Chevrolet Camaros, Corvettes, and various Chevrolet and GMC trucks and full-size cars.

When installing this kit, ensure your engine meets the specified compression and stall speed requirements for optimal performance. Proper tuning will also be essential to take full advantage of the camshaft's capabilities. Always refer to the included instructions for detailed installation procedures and break-in recommendations.
