4.6L FORD 2V-WHAT WORKS? WE TEST Heads, Cams & Nitrous! These just a few of the POWER upgrades we applied to the 4.6L 2V motor. We took a 1998 Non-PI motor, started with upgrading cams, then added nitrous, then followed up with fully ported PI heads, PI intake and AccuFab Elbow and TB. HOW MUCH POWER IS EACH MODIFCATION WORTH?
