Well alot of stuff has to change. My 331 was going to be very simple with very few wires, mechanical gauges, hei dizzy etc it I am not going that path because the nys DMV has to be difficult and if I were to make that it has to be a track only car, so I said ok whatever I want to be. A street car so I debated a 5.4 swap cause it's basically a 330 but I heard mixed things about it and I settled on a 4.6 build. I planed on a pretty much stock block and just building the top end. I was going to get stock harness and ecu and everything else. Buty next question is say I got the moduler version of the tranny can I make it in to a Manuel valve body and not have any issues with the computer?
