Ford Performance 5.0L Drag Race Roller Camshaft M-6250-X303

If you're building a serious drag race engine or looking to wake up your Fox-body Mustang with genuine performance gains, the Ford Performance 5.0L Drag Race Roller Camshaft M-6250-X303 is the foundation you need. This purpose-built cam delivers the aggressive power band and distinctive lumpy idle that separates modified 5.0L engines from the stock units, with peak gains extending to 6200 RPM. Engineered specifically for hydraulic roller applications in 1985-1995 Mustangs, it bridges the gap between streetable drivability and legitimate drag strip performance.
