ive got a 68 w/ a 302, I dont like having a C4 so i bought a AOD from a junk yard out of a 85 f150. I read that the truck transmission is stronger. Im wondering what kind of fly wheel I need to use. I have a 28oz 157 tooth that came with my engine, Ive read that ur supposed to use a 28oz 164 tooth but I dont want to go and buy one unless I have to. can some one whos done this swap give me some advice, mebey instead of some one giving me a link to a web site cuz trust me I ve looked at em all.
