COMP Cams Camshaft Set F4.6 3V XE272Ph

This is the COMP Cams XE272Ph camshaft set, designed for Ford's 4.6L and 5.4L 3-valve modular engines. If you're looking to significantly boost the performance of your supercharged Ford, especially in the mid to upper RPM range, this camshaft set is built for that purpose. It's engineered to work with bolt-on supercharger setups running high boost, aiming for substantial power increases where you'll feel it most during spirited driving or track use.

The XE272Ph features a 237/248 degree intake/exhaust duration and a hydraulic roller finger follower design. This camshaft is intended for serious power gains above 4900 RPM, making it a popular choice for enthusiasts pushing their supercharged 3-valve engines to the limit. Because of the aggressive nature of these cams, they require an upgraded valve spring and phaser setup to handle the increased lift and duration safely. You'll also need a custom tune to optimize the engine's performance with these new camshafts installed. For best results, COMP Cams recommends pairing this setup with rear-end gears of 3.90 or numerically higher and a torque converter with a stall speed of 3000 RPM or more.

Installing this camshaft set is a significant undertaking that will require careful attention to detail and likely some specialized tools. It's crucial to follow the manufacturer's installation instructions precisely, especially regarding the valve springs and phaser modifications. This camshaft set is not CARB approved and cannot be shipped to California. It's designed for a range of Ford, Lincoln, and Mercury vehicles including the Mustang, Expedition, F-150, and Navigator.
