New to this forum and had a question. I looked around and couldn't find what I needed. I have a 79 f150 460 c6 4x4 and a 94 f150 4x4 302. The 79 body and interior is shot but the drive train is amazing. The 94 is tired and tranny sucks and i don't like ttb but the body is nice with new paint. I want to make one truck. Would it be easier to swap drive train I to 94 or put 94 body on 79 frame? I've read all I can about SAS and 460 swap. Can't find anything about a body swap. It's going to be a winter project either way. Any help would be appreciated.
