COMP Cams Camshaft Kit CB 286H

If you're looking to give your Chevrolet Big Block engine a serious performance boost, this COMP Cams CB 286H Camshaft Kit is a solid choice. This kit is designed for engines originally equipped with flat tappet camshafts, specifically the 396 to 454 cubic inch displacements. It's built to deliver a noticeable increase in power and torque, especially when paired with the right supporting modifications.

This isn't just a camshaft; it's a complete K-Kit, meaning you get everything you need to get the job done right. Inside, you'll find the CB 286H camshaft itself, along with hydraulic lifters, valve springs, retainers, valve locks, and valve stem seals. To ensure a smooth installation and proper break-in, COMP Cams also includes assembly lube and detailed instructions. A timing chain set is also part of the package, making this a comprehensive solution for upgrading your engine's valvetrain. Expect a choppy idle with this camshaft, a characteristic sound that many performance enthusiasts appreciate.

For this camshaft kit to perform at its best, it requires specific supporting modifications. COMP Cams recommends a minimum of 9.5:1 compression, a 2800+ RPM stall speed torque converter if you have an automatic transmission, headers, and lower rear-end gears. This setup ensures the engine can take full advantage of the camshaft's improved airflow characteristics. This kit fits a wide range of Chevrolet vehicles from the late 1960s through the early 1980s, including popular models like the Chevelle, Impala, and C10 pickups.
