COMP Cams Camshaft Set F4.6S XE274H-14

The COMP Cams Xtreme Energy XE274H-14 camshaft set is built with a 236/240 degree intake/exhaust duration at .050 lift, a common choice for hot street applications on Ford's 4.6L and 5.4L 2-valve Modular engines. This camshaft is designed to work well with rear axle ratios in the 3.55 to 3.73 range and requires a torque converter with at least a 2000 RPM stall speed to keep the engine in its powerband. Because this camshaft significantly alters the engine's breathing characteristics, a custom tune is essential for optimal performance and drivability.

This camshaft set is a well-built component for those looking to extract more performance from their Ford Modular engine. It's engineered to provide a noticeable bump in power for street-driven vehicles, but be aware that the aggressive nature of the Xtreme Energy series means you should expect a rougher idle compared to stock. This is a trade-off for the improved performance, and it's a characteristic many enthusiasts are willing to accept for the enhanced power delivery. The hydraulic roller finger follower design helps reduce friction and wear compared to older flat tappet designs.

This camshaft set fits a wide range of Ford, Lincoln, and Mercury vehicles, including popular models like the Ford Mustang, Crown Victoria, and Expedition. Installation will require removing the intake manifold, valve covers, and timing components. Remember that this part is not CARB approved and cannot be shipped to California. A custom ECU tune is mandatory for proper operation.
