The Ford 4.6L Modular 3V Ford Mustang engine has become increasingly popular, so now the question is – how can we further improve the performance of it? COMP Cams® has built upon Ford’s technology with a series of camshafts created specifically for these engines.

We recommend a custom tune with all cam installations
