Product Details

This is the COMP Cams Xtreme Energy XR280 R-10 solid roller camshaft, specifically designed for Ford 429 and 460 Big Block engines. If you're building a street machine that needs a significant performance boost, this camshaft is engineered to make a real difference. It's a solid roller design, which means it can handle higher lift and RPMs compared to flat tappet cams, allowing for better airflow and more power.

The XR280 R-10 is a popular choice for builds aiming for a strong street presence. It's matched with an intake duration of 242 degrees and exhaust duration of 248 degrees at .050 inch lift, giving it a noticeable idle and a broad power band. For this camshaft to perform at its best, COMP Cams recommends a minimum compression ratio of 10:1 and a torque converter with a stall speed around 2800 RPM. It also pairs well with rear axle gear ratios in the 3.73 to 3.90 range, which helps keep the engine in its power band during acceleration. This camshaft is a substantial upgrade for those looking to get the most out of their Ford Big Block.

This camshaft fits a wide range of Ford and Mercury vehicles from the late 1960s through the 1990s, including popular models like the Ford F-150, Ford Gran Torino, and Lincoln Continental. It's important to note that this part is not CARB approved and cannot be shipped to California. Always consult the manufacturer's installation instructions for proper setup and break-in procedures.
