hey whats up? i am doining the same swap and i am learning alittle more each day. i know that all you need is motor mounts, bellhousing, clutch/flywheel assembly, and a couple basic ods and ends....you can use your radiator until you get into the high performance mods. you can use the 4 bangers tranny also but you need to get a pilot bearing for a thunderbird turbo coupe because the shaft is not the same size as a 302. you should go ahead and re-run your fuel lines with sum steel braided hose and stuff like that. you will obviously need a header back exhaust for a 5.0 .thats really all i know as of right now. i havent completed my swap in my 89 hatch stang either so i am sure i will run into a couple more things before i am done.
