COMP Cams Camshaft Kit FW XR276H-R12

The COMP Cams XR276H-R12 camshaft kit is built around a camshaft featuring a 224/230 degree intake/exhaust duration split, designed for computer-controlled Ford 5.0L engines. This specific camshaft profile is a popular choice for those looking to make significant modifications to their engine, aiming for improved performance beyond stock specifications. It’s intended for use with 1.7:1 ratio rocker arms, which help to further optimize valve lift and timing for better airflow and combustion efficiency.

This is a complete K-Kit, meaning it includes everything you need to swap out your old valvetrain components and install the new camshaft. You'll find the camshaft itself, a set of lifters, valve springs, retainers, valve locks, and valve stem seals. To ensure proper timing, a new timing chain set is also included, along with assembly lube and installation instructions. This comprehensive approach helps ensure a smooth installation and a well-matched valvetrain system.

For this camshaft kit to perform at its best, it requires supporting modifications. COMP Cams recommends a rear axle gear ratio of 3.55 or lower (numerically higher, like 4.10) and a torque converter with a stall speed of 2500 RPM or higher. These components help keep the engine in its power band, especially during acceleration. This kit fits a range of Ford and Mercury vehicles, including popular models like the Ford Mustang, F-150, and Mercury Cougar from the mid-80s to mid-90s.
