Product Details

This is the COMP Cams Xtreme Energy XE274H-10 camshaft, part number 21-224-4. It's a hydraulic flat tappet camshaft designed for high-performance street use in Chrysler 383, 400, 413, 426 Wedge, and 440 cubic inch engines. If you're looking to get more out of your big block Mopar, this cam can really wake up the mid-range power.

The XE274H-10 is built for strong mid-range torque, especially when paired with headers and a torque converter with a stall speed of 2200 RPM or higher. This means you'll feel a noticeable improvement in acceleration when you're cruising and need to pass. It's a well-built component that offers a significant step up from stock performance for a wide range of Chrysler, Dodge, and Plymouth vehicles from the late 50s through the late 70s.

Keep in mind that this camshaft is not CARB approved and cannot be shipped to California. You'll also want to ensure you have the proper valve springs and pushrods to match the camshaft's specifications for optimal performance and reliability.
