Ive heard that if you put a C6 in a 64 body that the firewall would need to be modified. Ok next thing I saw, do they make a 4spd for the 460? The car has a three on the tree, but I was looking at a rack kit and it comes with a new column. Im thinking floor shifter here.. hmmmm ok I forgot to ask also.. does the front end need a new crossmember or anything since it is a 6cyl car or would just dropping in the new V-8 be A-OK? I hate to be a pest but I am new to Ford customizing, thanks all!
