351M/400 were the only engine options I beleive. Not sure about the rest. You'll probably get more info in the 73-79 f-series forum as a bronco shares more in common with the 78-79 f-series than with 80+ broncos, just a suggestion.

The "S" engine code is for a 400. As far as performance, you can ditch the emission stuff as long as it doesn't create a problem(state inspection) in the state where you live. I have a 78 and the smog stuff was pulled on it before I bought it by a previous owner.

Like previously said only 351M/400s were options, but you can easily swap in new front engine mounts and put a 460 in w/out any other mods.
