i know, it is easier w/ the 302, and an HO upgrade wont hurt. i think a wrecked mustang would be the best for getting the parts, but i haven't found the right one yet. i just recently put 245/50/16 in the back. you never know, you might find a strong engine the other day.
by the way, i was offered a 4.6 out of a cougar, but i've heared that it could be a real pain in the a.. to get that thing to run the way it is supposed to run.
