Product Details

COMP Cams is well-known for performance engine components, and their High Energy camshafts are a popular choice for those looking to improve their engine's power and torque. This CRB 268H-10 camshaft, part number 21-215-4, is designed for Chrysler B/RB engines like the 383, 400, 413, 426 Wedge, and 440. It's a great replacement option for a 383 Magnum, especially when paired with a 650-750 CFM carburetor and a dual-plane intake manifold.

This camshaft is built to provide a smooth idle while delivering super torque, making it a solid option for street performance applications. The 218/218 duration at 0.050 inch lift is a well-balanced profile for these larger displacement Mopar V8s, offering a noticeable improvement over stock without being overly aggressive for daily driving. It's a hydraulic flat tappet design, meaning it uses standard lifters and is a direct replacement for your original camshaft.

If you're rebuilding a Chrysler 383-440 engine and want improved low-end torque and a strong mid-range pull, this COMP Cams camshaft is worth considering. Keep in mind that this camshaft is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and break-in procedures.
