Okay thanks r3dn3ck. I've got plenty of time before the project materializes, so maybe something new will come out. If worst comes to worst, I'll hand port the adaptors or simply just stay EFI. Do the adaptors have plenty of material to port? And do you use a dremel tool or what?

You could modify the Edelbrock 4.6 intake by cutting it down the middle of the plenum, widen it, and then machine an adaptor to go from the wider mounting point to a standard carb mount. This way, you enlarge the plenum for performance and add a spacer for the carb.

Could be done, but a lot of work. All someone like Edelbrock would have to do is widen there 4.6L manifold in a program and with the press of a button have a new 5.4L manifold. Oh well....
And also, does anyone have any good links to read up on carbureted modulars? I can't seem to find much. I have a few questions I'm trying to figure out, like what needs to be done with the fuel system? I'm assuming I could get a regulator to lower the fuel pressure and that's it...
