Product Details

COMP Cams is well-known for performance engine components, and their Xtreme Energy line is designed to give your engine a serious boost. This XR276HR-13 hydraulic roller camshaft is built for Chevrolet Big Block Gen VI engines, specifically those from 1996-2000. If you're looking to wake up a big block in a truck like a C2500 Suburban or an Express 3500, this cam can make a notable difference in how your vehicle performs.

This camshaft features a 224 intake duration and 230 exhaust duration, making it a popular choice for performance applications. To get the most out of this cam, it's recommended to pair it with custom engine tuning and a torque converter with at least a 2200 RPM stall speed. This setup helps ensure the engine can take full advantage of the improved airflow and valve timing the camshaft provides, especially at higher RPMs. It's a solid option for anyone rebuilding or modifying their big block for more power.

When installing this camshaft, remember that it's designed for hydraulic roller lifters, which are generally more durable and offer better performance than flat tappet designs. Make sure you have all the necessary supporting modifications and components in place to match the cam's aggressive profile. This is not CARB approved and cannot be shipped to California.
