The COMP Cams Xtreme Energy XR276HR hydraulic roller cam is aimed at modified LT1 engines seeking stronger top- and mid-range power. It performs best with improved exhaust flow and a higher-stall converter (2000+ RPM), and requires a custom tune to integrate the cam’s profile with engine controls. Choose this cam when planning additional supporting modifications for reliable street performance.
