Product Details

If you're building a serious street machine for your Ford 429 or 460 big block, this COMP Cams Xtreme Energy XR280 R10 solid roller camshaft and lifter kit is a popular choice. This kit is designed to work with engines featuring 10:1 or higher compression ratios, a 2800 RPM stall torque converter, and 3.73 to 3.90 rear axle gears. It's a well-known option for those looking to significantly improve performance in applications like the Ford Country Squire, Mercury Marquis, or Lincoln Continental from the late 60s through the mid-70s.

This kit includes the camshaft itself, a set of solid roller lifters, assembly lube to ensure proper break-in, and decals. The XR280 profile is engineered to provide a noticeable increase in power and torque, especially in the mid to upper RPM range, making it suitable for vehicles that see regular use but demand more aggressive performance. The solid roller design means it requires a robust valvetrain setup, so ensure your components are up to the task.

When installing this kit, it's crucial to follow the included instructions carefully, especially regarding the camshaft break-in procedure. Proper lubrication and initial run-in are key to the longevity of both the cam and lifters. Remember that this part is not CARB approved and cannot be shipped to California.
