COMP Cams Camshaft CB XR286 R-10

COMP Cams is well-known for its performance camshafts, and the Xtreme Energy line is a popular choice for drivers looking to get more out of their engines. This particular camshaft, the XR286 R-10, is a solid roller grind designed for Chevrolet Big Block engines like the 396, 427, and 454. It features a quicker valve opening profile, which means more area under the lift curve compared to older, slower camshaft designs. This translates to increased responsiveness and noticeable gains in both torque and horsepower.

What's great about the Xtreme Energy series is that COMP Cams aims to boost performance without sacrificing everyday driveability. This camshaft should still provide adequate vacuum for essential accessories like power brakes, even with its performance-oriented design. While it works well in carbureted setups, you'll see the best results when paired with aftermarket intake manifolds, lower gear ratios, headers, and a free-flowing exhaust system. This camshaft is particularly well-suited for weekend warrior builds with a 3000+ RPM stall torque converter.

This camshaft fits a wide range of Chevrolet vehicles originally equipped with flat tappet camshafts, including models like the 1967-1975 Chevrolet Bel Air, 1967-1972 Chevrolet Biscayne, and 1973-1974 Chevrolet Blazer, among many others. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and any required supporting components.
