Product Details
When you're building a street/strip Ford small block, this COMP Cams Xtreme Energy camshaft is what you get in the box. It's designed for Ford 221, 255, 260, 289, and 302 engines, offering an improved performance profile for vehicles like the Ford Bronco, F-150, and Mustang.
This camshaft features a 240/246 degree duration at .050 lift, which is a solid choice for street performance applications that also see track time. It's built to work well with a 2800+ RPM stall torque converter, headers, and a gear change, giving you that extra kick when you need it. Expect a noticeable, rough idle with this cam, which is part of its aggressive street/strip character. It’s a well-built component designed to handle the demands of spirited driving and occasional track use.
For optimal performance and longevity, COMP Cams recommends pairing this camshaft with appropriate supporting modifications and ensuring your valvetrain is in good condition. Remember, this camshaft is not CARB approved and cannot be shipped to California.
