COMP Cams Xtreme XE-R 238/240 hydraulic roller cam set for Ford 4.6/5.4/5.8L modular 4-valve engines, tuned for maximum strip and street performance with centrifugal superchargers or nitrous. The cams produce large gains when paired with a larger throttle body, mass-air, injectors and exhaust upgrades; a 2500+ stall converter and lower gearing are recommended, and custom tuning is required.
