COMP Cams Camshaft Set F4.6/5.4D XE266B

COMP Cams is well-known for performance valvetrain components, and their XE266B XRPM camshaft set is built for serious street performance. This camshaft is designed for Ford's 4.6L, 5.4L, and 5.8L modular 4-valve engines, aiming to deliver maximum power gains in the mid to upper RPM range. If you're looking to push your engine beyond stock, this camshaft set is a strong option to consider.

This camshaft features a 230/230 degree duration split and operates as a hydraulic roller finger follower system. To take full advantage of the increased airflow and power this camshaft offers, you'll need to make some supporting modifications. This includes computer modifications and custom tuning to optimize the engine's performance. For vehicles equipped with an automatic transmission, a torque converter with a 2000+ stall speed is recommended to keep the engine in its power band. Lower gear ratios are also required to effectively utilize the power gains, especially in the mid to upper RPMs.

While this camshaft set is designed for serious street performance, expect a mildly rough idle due to its aggressive profile. It's important to note that this camshaft is not CARB approved and cannot be shipped to California. This camshaft set fits a wide range of Ford, Lincoln, and Mercury vehicles, including models like the Ford Mustang, Ford GT, and Lincoln Navigator.
