Well, lets see....First...If the frame is messed up....Some things may have gotten twisted...cracked etc...so ya may wanna watch out for that. Secondly, as for me installing mine...I'm going to have a shop build a motor for me, and I'll do the actual instal. Now, I can spin wrenches deceintly....I've done most of the mods on my truck thus far. I don't know your capabilities....Everyone who has done the swap, say it doesnt take a rocket scientist, it just takes time. I plan on starting on a thursday or friday night, and only work half days for the next week so i can come home and work on it. I cant help ya on the mclaren stang, but i think they were more powerful than the regular 5.0's but you are gonna wanna have it rebuilt. Gofast is useing the aod as well, but then you need an expensive adapter to adapt the tranny to t-case. I am going to run a C-4 and a dana 20 t-case out of a EB. Oknut ran all james duff swap parts and told me it went in easily, so I'm looking to do the same. That's all I can think of now, if ya got any other questions, i'll try and help, if not, check gofasts thread
