I"m thinking of taking an automatic 5.0 and swapping in my built(somewhat) T-5 into it. It's already got the gears in the tranny for the 3.73's i would be putting in too. The question is should i do a computer swap and all of that at the same time? I was going to be putting in the E303 cam at the same time, so i was thinking of gettting the Ford motorsports kit with the 93 computer, 70MM mass air, and 24# injectors. I've heard that the 93 computer works better, especially with the E cam anyways. What would i need to swap the computers and all anyways? Is it too much cost/hassle?
