COMP Cams Camshaft FC XE284H-10

If you're building a street/strip Ford with a 351 Cleveland, 351 Modified, or 400M engine, this COMP Cams Xtreme Energy camshaft is designed to give you a noticeable bump in performance. It's a hydraulic flat tappet cam, meaning it uses a familiar and robust valvetrain design that's common in many classic Ford V8s. This cam is specifically tuned for applications that already have supporting modifications like a higher stall torque converter (2800+ RPM), a compression ratio around 9.5:1, headers, and appropriate gearing.

The XE284H-10 features a 240-degree intake and 246-degree exhaust duration at .050 inch lift. This duration profile is aggressive enough to make significant power in the mid-to-upper RPM range, which is exactly what you want for spirited driving and track use. Because of this aggressive profile, expect a rougher idle than stock, which is a common characteristic of cams designed for this kind of performance. It's a well-built piece from COMP Cams, a popular name in performance engine components, and it’s made to handle the demands of a performance-oriented build.

This camshaft fits a wide range of Ford and Mercury vehicles from the late 60s through the mid-80s, including models like the Ford Mustang, F-150, and Mercury Cougar. Make sure your engine has the necessary supporting modifications to take full advantage of this cam's capabilities. It's a solid option for anyone looking to extract more power from their classic Ford V8.
