A: The AMC 2.5 with 1 bbl TBI should fit better by an inch or so.

There's only a couple inches difference (estimating from the pics), but that's enough! Take the outer barrel off the carb intake and it would fit. The left to right placement of the two barrel carbs is what I found that prevented using a modern four cylinder also. I didn't find one that placed the barrels front to back and a bit closer to the head. Since they all used progressive linkage the side to side mount works better. The early 2.3L Ford used progressive linkage, but I don't recall if the barrels are side to side or front to back. I do recall the intake doesn't stick out as far as later, better flowing ones. The early American engine bay is tighter side to side than the early Mustang/Falcon/64-69 American. That engine barely fits in a Mustang bay. The header shown on the Ford Six site won't fit either. I'll haveto check, but I seem to recall the engine bay as being 23-24" between the suspension mounting points. It gets wider above the upper control arm mounting points, but the distance between the humps is only a couple inches more at the peak of the hump. The humps stick out at least two inches from the rest of the inner fender panels. Cut the humps at just the right spot and you can weld the inner panel to the outer without adding metal (I THINK...), but I'd add a piece anyway for strength. _________________________________________________________________ Turn searches into helpful donations.
