Okay, I found a Met with a 2.3 Ford and a C4 stuffed in. It is all motor from the radiator to the steering link (that runs above the trans).
I think this gives a great deal of insight into the potential of a EFI 2.3 and AOD trans or five speed option - then adding a turbo would be the real trick. There is a ton of room inside the fenders to run plumbling.
