Well, the engine I was thinking about which I saw on an engine stand at the January swap meet in denver, was the 5.4 DOHC and it was HUGE.

I think if I was going to run the 4.7 in something it'd be like a 68 Dart and I'd probably use the Ford EEC IV control system from a '90s Mustang. There's a wealth of info and parts out there. Of course, I would be using a manual transmission, probably somethig like a World class T5.
But we're way off topic here, the OP wanted to know and I think he's gotten a pretty good look at the problems he'd be facing.
