Product Details

The COMP Cams XE284H-10 camshaft kit features a 240/246 degree intake/exhaust duration at .050 lift, a design choice that significantly impacts how your engine performs. This kit is specifically built for Ford Big Block 429 and 460 engines, fitting a wide range of vehicles from the 1969-1974 Ford Country Sedan to the 1983-1994 Ford F-250 and F-350, among many others. It’s intended for street/strip applications where you’re looking for improved performance, often paired with a 2800+ RPM stall torque converter and a 9.5:1 compression ratio.

This kit comes with everything you need to get the job done: the camshaft itself, a set of hydraulic lifters, a complete timing chain set, assembly lube to ensure proper break-in, and decals. The Xtreme Energy design of this camshaft is known for its aggressive lobe profiles, which contribute to a rougher idle but deliver strong mid-range and top-end power. Expect a noticeable idle sound that signals this isn't your stock engine anymore. It’s best suited for lower gear ratios to help put that power to the pavement effectively.

When installing this camshaft kit, remember that it’s designed for engines with at least 9.5:1 compression and often benefits from lower rear-end gears to maximize its performance potential. While it offers a significant performance bump for your Ford Big Block, it's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's instructions for detailed installation procedures and break-in requirements to ensure optimal performance and longevity.
