I have a 65 Mustang. Right now it's a slow 6 cylinder, and I want to convert it to a V8, probably a 302. I know that if I get a new engine, I also need a new transmission and a bunch of other stuff. Can someone please outline for me exactly what other stuff I need replaced in order to convert my Mustang? Also include prices I can expect to pay for each thing. One place quoted me $8000-$9000 for parts and labor for everything needed, but he refused to break it down for me, so I left. Any help would be appreciated.
