StangDB

Ok, i have my 347 built and i have talked to some auto yard guys, and even Mustang guys, and what theyve been telling me is(man your gonna blow that c4 up faster than you put it in) Then ive been told that the C6 Auto tranny is "tougher" and better. Ive looked on here and found that the gear ratios aresimular, there both 3spd's and also have a intercooler. I really want to stick with an automatic, anybody got advice?
