COMP Cams Camshaft CB XR282HR-10

This COMP Cams Xtreme Energy camshaft features a 230/236 degree intake/exhaust duration at .050 lift, a notable design choice that contributes to a quicker valve opening. This profile is built to increase responsiveness and create more area under the lift curve compared to older, slower camshaft grinds. It's designed to boost performance in street cars, aiming for gains in torque and horsepower without sacrificing essential driveability and creature comforts. You can expect adequate vacuum for power brakes and other accessories, making it a solid option for carbureted applications, especially when paired with aftermarket intake manifolds, lower gear ratios, headers, and a free-flowing exhaust system.

The XR282HR-10 is a hydraulic roller camshaft intended for Chevrolet Big Block 396-454 engines that originally came with flat tappet camshafts. For optimal performance and reliability, it's recommended for applications with a 2200+ RPM stall speed torque converter, a compression ratio of 9:1 or higher, and the use of headers. This camshaft is a popular choice for street performance builds, offering a significant improvement in engine breathing and power output. It's important to note that this camshaft is not CARB approved and cannot be shipped to California.

When considering this camshaft, ensure your engine setup can support its requirements. This includes having the correct valve springs and potentially upgraded valvetrain components to handle the increased lift and duration. It's also a good idea to consult with a performance engine builder to confirm compatibility with your specific engine build and intended use. This camshaft is designed to work well with a variety of Chevrolet vehicles from the late 1960s through the early 1990s, including models like the Chevrolet C10 Pickup, Chevrolet Impala, and Chevrolet Camaro, among many others originally equipped with the 396-454 Big Block engine.
