The tripower you refer to is from a 1963 M-code or sports roadster. That car is completely different than a 67 t-bird. The intakes on a 67 t-bird and a Mustang LOOK almost identicle but they carry a different part number but will interchange fine. The engine mounts would definately be different but you change those over when swapping the engine to the Mustang. (these mounts are expensive too, about $300 a pair) The mounting holes on the side of the block are the same for all 390's, 352's, 410's and 428's. The 427 mounting holes are just a touch different.
I don't know a lot about anything, but I know a little about everything.
Built a 1967 Shelby GT-350 Convertible Replica, a 67 Vert resto-mod and also built a 427 FE 67 Shelby GT-500R (R Stands for Replica). 427 Side Oiler, toploader 4spd, 4 wheel discs, 9" traction loc and a perfect body. What more could you ask for? Now I car hunt and horse trade and I am currently looking for the next project! Always seeking that elusive "reasonable" Shelby.
