The COMP Cams F4.6 3V XE261H-1 camshaft set is designed for enthusiasts seeking improved performance in Ford 4.6L and 5.4L V8 engines, particularly those equipped with high-boost bolt-on superchargers. Crafted to deliver mid to upper-range power, this camshaft enhances throttle response and idle quality while providing significant horsepower gains above 4900 RPM. The set requires a spring upgrade to handle high lift and aggressive valve operation, ensuring durability and optimal performance during high-RPM activity. This camshaft is ideal for engines paired with a stall converter of 3000 RPM or higher for maximum efficiency and power delivery. Its compatibility spans several Ford models including F-150, F-250, F-350 Super Duty, Expedition, Lincoln Navigator, and Mercury Mountaineer, covering model years from 2004 to 2014.

The installation of this camshaft set necessitates custom tuning to optimize engine parameters and ensure reliable operation. It is not CARB-approved, making it suitable primarily for off-road or race applications where emissions compliance is not required. The product is not intended for use with EPA-regulated vehicles, and proper acknowledgment of carb exemption is required during installation. As a specialty automotive part, it is designed for performance upgrades and should be installed by qualified technicians familiar with high-performance Ford engines. The set is shipped as a complete package, ready to replace your stock camshaft with a high-performance alternative that unlocks additional power and responsiveness in your vehicle.

Note that this product is not stocked as a regular item and is intended for custom applications, ensuring you receive a high-quality component tailored for serious performance upgrades.
