I would go with the biggest motor possible. A 302 done out to a 347 would work great, and the outside dimensions would fit. But for a little work a 351 done out to 400 or more cubes would be really great. I think there have been 351s done out to 427s.
There used to be kits to put a 460 in Fox bodies. Maybe they are still available.
Sadly, the 3.8 was a better performer than the 255 V8.
I've personally witnessed a 3.8 2bbl V6 1983 Mustang GL hatch run away from a 4.2 255 V8 Mustang notch over and over again. The numbers were there for the V8. It should have at least kept up. That V6 stomped it. It sounded healthy.
Can't say for sure.
IIRC, the 255 V8 cars all got 3-speed autos and 2.26 gears.
The V6's may have gotten OD and had deeper (3.08, maybe 3.27) gearing.
The GL 3.8 had a 3 speed. Probabaly a C5. I never paid attention to whether or not it went into lockup. It had been a rental car at one time. I dated the girl that owned it but never crawled under to see. Don't know what the rear ratio was. I'm guessing the open diff 3.08. My friend's Turbo Fairmont would eventually catch it, but she would holeshot him badly.
You're probably right about the rear axle ratio. I think you could order the Traction Lok 3.08 for the 255 Mustang but you probably had to get the Cobra sticker package. His was a one wheel wonder Ghia coupe. (identified by his poor attempts at a burnout)
I think my 2.3 4 speed could have given that 255 a run.
It certainly did better one wheel burnouts
