The COMP Cams valve-springs-required cam for Ford 4.6/5.4L modular 3V engines is an upgrade that delivers solid power gains above 4,400 RPM. It requires a spring upgrade and a tuner is recommended for best results; stock gears and converter are generally acceptable. This cam offers a noticeable performance step over stock when properly supported by valve springs and tuning.
