COMP Cams Camshaft CB8 XR270 HR14

If you're looking to get more out of your GM 8.1L engine, especially in performance applications, a camshaft upgrade like this COMP Cams XR270 HR14 can make a notable difference. This hydraulic roller camshaft is designed to work with the factory roller lifters and features a 218-degree intake and 224-degree exhaust duration, measured at .050 inch lift. This profile is a popular choice for those rebuilding or modifying their engine for increased power and responsiveness.

This camshaft is built for performance, and you'll likely see the best results when paired with aftermarket intake and exhaust systems that can help your engine breathe more freely. The hydraulic roller design means it's designed to work with your engine's existing roller valvetrain, simplifying installation compared to a flat tappet cam. While it's a direct replacement for the stock camshaft in many GM trucks and SUVs like the Chevrolet Silverado 2500 HD, Suburban 2500, and Avalanche 2500, it's important to remember this is an aftermarket performance part. It's not CARB approved, so it cannot be shipped to California.

When installing a performance camshaft, it's always a good idea to consult the manufacturer's detailed installation instructions. This ensures proper timing and valvetrain setup, which is crucial for achieving the desired performance gains and ensuring the longevity of your engine. This camshaft is a solid option for anyone looking to push their GM 8.1L engine beyond its stock capabilities.
