In the below link you can see how Ford built a one off 1970 Maverick show car "The Mavi GT" to give the public an idea of what could be accomplished with a mildly built 250 six and Tri power. With the shorter deck 200 it wouldn't need much of a scoop if any. The Offy Tri power set up fits in under the low hood of the 1965 & 1966 Mustangs with only a little work see second video for info of how one of our site members did it. Good luck
