COMP Cams Camshaft CBVI XR276HR-10

This COMP Cams XR276HR-10 camshaft features a 224-degree intake and 230-degree exhaust duration at .050 lift, with a .574-inch intake and .574-inch exhaust lift. This hydraulic roller grind is designed for Chevrolet Big Block GEN VI engines, specifically targeting high-performance street applications. The Xtreme Energy profile is engineered to provide a quicker valve opening, which translates to increased responsiveness and a broader area under the lift curve compared to older camshaft designs. This means you get more torque and horsepower gains without sacrificing the driveability needed for daily use.

COMP Cams designed the Xtreme Energy line to enhance performance while maintaining adequate vacuum for essential accessories like power brakes and other vacuum-dependent systems. While this camshaft works well in carbureted setups, you'll see its best performance when paired with aftermarket intake manifolds, lower gear ratios, headers, and a free-flowing exhaust system. This camshaft is a solid option for those looking to build a powerful street machine that still behaves well on the road. It fits a range of vehicles including 1996-1999 Chevrolet C2500 Suburban and 1996-2000 GMC C3500 models.

For optimal results with this camshaft, consider pairing it with a higher stall torque converter, typically 2000 RPM or more, along with the recommended intake, headers, and exhaust upgrades. Please note that this camshaft is not CARB approved and cannot be shipped to California.
