The Xtreme Hydraulic Roller Cam for Small Block Chevy (XR276HR) is designed for automotive enthusiasts and builders looking for dependable, street-friendly performance. This camshaft from COMP CAMS provides smooth and quiet operation, making it suitable for daily drivers, weekend projects, and restorations that require both drivability and notable power improvements.
Featuring a hydraulic roller design, the XR276HR camshaft reduces valve train noise and wear on critical engine components compared to traditional flat-tappet designs. The roller lifters ride on hardened steel lobes, significantly lowering friction and heat generation throughout the valve train. This hydraulic mechanism automatically adjusts for thermal expansion and wear, ensuring consistent valve timing and lash across various engine operating temperatures.
The XR276HR is specifically engineered for 262–400 cubic inch Small Block Chevy engines equipped with standard rectangular-port heads and intake manifolds, making it compatible with a wide range of SBC applications from 1955 onward. This camshaft is an excellent choice for those seeking to enhance their engine's performance while maintaining reliability and ease of use.
