COMP Cams Camshaft CS XR286 R-10

If you're looking to get more out of your Chevrolet Small Block Gen 1 engine, especially for weekend warrior duty with a higher stall torque converter, this COMP Cams Xtreme Energy camshaft is a solid choice. It's designed to give you a noticeable bump in torque and horsepower without making the car uncomfortable to drive or sacrificing essential functions like power brakes, which rely on engine vacuum. This particular grind, the XR286, features a quicker valve opening and a more aggressive lift curve compared to older camshaft designs, which translates directly into improved engine responsiveness.

This camshaft is a solid roller type, meaning it uses roller lifters to reduce friction and allow for more aggressive lobe profiles, which is key to achieving those performance gains. For the best results, COMP Cams recommends pairing this camshaft with a good aftermarket intake manifold, headers, and a free-flowing exhaust system. It's also best suited for applications running lower gear ratios, which help keep the engine in its power band. While it works with carbureted setups, you'll see the most significant improvements when you combine it with these other performance upgrades. It's important to confirm your engine is a flat tappet block, as this camshaft is not designed for factory roller blocks from 1985 and newer, or for LS-based engines.

This camshaft is designed to fit a wide range of Chevrolet Gen 1 Small Block engines, including popular displacements like the 350, 327, and 400 cubic inch V8s. It's a great option for many classic GM vehicles, from muscle cars like the Camaro and Chevelle to trucks and even some older Cadillac models. Remember to check your specific engine block to ensure compatibility, especially regarding the factory roller versus flat tappet setup.
