You'll be well into a nice SVO by the time you get a swap into a "regular" stang. I wouldn't bother with it. But many people try.
I know two guys in B'ham area who each have SVO's one is an '84 with all '86 updates; he's owned it since new. The other is an '86.
Both of the cars have T3/T4 turbo, front-mount ic, exhaust, fuel pump, A237 (FRPP) cam, and supporting hardware. At blakes, they lay down right around 300 to the tires. I've seen them go low 13's...perfectly streetable too.
The SVOCA is having a dyno day at Walker Dynotune in two weeks (Fri Sept. 1st):
