Product Details

This COMP Cams FF 280A-R10 camshaft is built with a mechanical roller design, which is a key detail for achieving serious street/strip performance. It's specifically intended for Ford Big Block engines, like the 429 and 460 series, and is designed to work well with a compression ratio of 10:1 or higher, a torque converter with at least a 2200 RPM stall speed, and headers. You can expect a noticeable, choppy idle with this camshaft, which is a common characteristic of performance grinds like this one.

When you're looking to get more out of your Big Block Ford, this camshaft is a solid option. The mechanical roller setup means less friction and more precise valve events compared to flat tappet designs, allowing for higher RPM operation and better power delivery. It's a component that really wakes up the engine, especially when paired with the right supporting modifications like those mentioned. This camshaft is designed to fit a wide range of Ford and Mercury vehicles from the late 60s through the mid-90s, including popular models like the Ford F-150, Ford LTD, and Mercury Marquis.

Installing a camshaft like this is a significant engine modification. It's recommended to consult the manufacturer's installation instructions for specific details regarding valve springs, pushrods, and break-in procedures to ensure optimal performance and longevity. This camshaft is not CARB approved and cannot be shipped to California.
