4.6-liter
One of the most misunderstood performance components on any engine has to be the camshaft, or camshafts in the case of our overhead-cam 4.6-liter Ford engine. The difficulty is only compounded when you add forced induction to the mix. From an anatomical standpoint, the camshaft can be likened to the brain, as the cam profile determines how effectively (when and where) breathing takes place.
