COMP Cams Camshaft Set F4.6/5.4D XE274B

The COMP Cams F4.6/5.4D XE274B is a performance camshaft set designed for high-horsepower applications. Featuring hydraulic roller finger followers, these cams are optimized for Ford 4.6, 5.4, and 5.8 modular engines. They are part of the Xtreme XE-R series, specifically engineered for supercharged or nitrous oxide-enhanced setups. The cams provide significant power gains when paired with upgrades such as larger throttle bodies, increased airflow via mass air sensors, high-capacity injectors, and exhaust modifications. Built for maximum strip and street performance, they support engines with stalls over 2500 RPM, but require lower gears and custom tuning. The rough idle characteristic indicates a performance-oriented profile that maximizes power output.

These camshafts are suitable for Ford modular engines from model years that utilize the 4.6, 5.4, or 5.8-liter configurations. They are intended for use in centrifugal supercharged or nitrous-injected engines, making them ideal for racing, high-performance street builds, or drag applications. Installation involves replacing the stock camshafts with these hydraulic roller units, which are designed as direct upgrades for compatible engines. The set is compatible with vehicles that have supporting modifications such as upgraded fuel systems and tuning. Proper tuning and lower gear ratios are recommended to maximize performance and drivability with these cams.
