COMP Cams Camshaft Set F4.6/5.4D XE278A

Take your Ford Mustang or Mercury to the next level with the COMP Cams Xtreme XE-R 278AH-14 Camshaft Set. Designed for 4.6L DOHC Modular 4 Valve Ford engines, this camshaft set is perfect for race or limited street use.

With its unique blend of lift and duration, this camshaft set delivers a very rough idle and requires a larger throttle body, mass air, injectors, exhaust upgrades, and custom tuning. Automatics need a 3000+ stall.
