Product Details

This is the COMP Cams Xtreme Energy camshaft, part number 21-221-4, designed for Chrysler B and RB series big-block engines like the 383, 400, 413, 426 Wedge, and 440. If you're looking to improve the torque output of your classic Mopar, this camshaft is a solid option. It's built to give you a noticeable boost in pulling power from the low end all the way through the mid-range, making it great for street driving and heavier vehicles. Plus, it's designed to maintain a good, manageable idle, so you won't have to sacrifice everyday drivability.

COMP Cams engineered this hydraulic flat tappet camshaft with a 212/218 degree intake/exhaust duration. This specific grind is known for its strong torque curve, which means your engine will feel more responsive when you get on the throttle. It fits a wide range of Chrysler, Dodge, and Plymouth vehicles from the late 50s through the late 70s, including popular models like the Dodge Charger, Plymouth Barracuda, and Chrysler New Yorker. While it provides improved performance, it's important to note that this camshaft is not CARB approved and cannot be shipped to California.
