Super Charger question!
I don't suggest it unless you are rebuilding the motor. you need all forged components or youll never get a reliable engine boosting your stock 5.4. Even with a newly built 5 4 youre not gonna get a long lasting 5.4 but if you don't care about getting 250k + miles out of your baby and just wanna have a fast pickup then build your engine with forged components and boost on. as for trans youll prob have to rebuild that to. and if you plan on going over 350-400hp than you need to swap in a 4r100. or you could build your 4r70w and it can take up around 600hp.
