COMP Cams Cam & Lifter Kit CBVI XR300HR

COMP Cams is well-known for its performance camshafts and valvetrain components, and this XE 248/254 Hydraulic Roller Cam and Lifter Kit is a prime example of their expertise. This kit is specifically designed for Chevrolet Big Block GEN VI engines, offering an improved performance profile for those looking to get more out of their large displacement powerplants. It’s a popular choice for bracket racing applications where consistent power delivery and a strong mid-range pull are essential.

This kit includes everything you need to get started: the camshaft itself, a set of hydraulic roller lifters, assembly lube to ensure proper break-in, and decals. The XE 248/254 grind is engineered to work well with larger cubic inch engines, and it’s recommended for builds that will utilize a 3500+ RPM stall torque converter. This combination helps keep the engine in its power band during acceleration, making it ideal for drag racing or other performance-oriented uses where you need a strong, reliable power curve.

When installing this kit, remember that it's designed for performance and may require other supporting modifications to achieve its full potential. Given its aggressive nature and intended use, it's a solid option for serious engine builds. Please note that this part is not CARB approved and cannot be shipped to California.
