Looking for an EFI 318

What kinds of cars/trucks would I find an EFI'd 318 that I can use in my '64 Dart? I'm thinking that by buying a complete, running vehicle for cheap would be easier and possibly even cheaper than trying to track everything down. It would certainly be faster.

What cars or trucks would you guys recommend? Is there any year EFI that I should avoid?

I've already got all of the engine peripherals that I think I need for the swap, including a 4-speed OD trans, with bellhousing, engine mounts, exhaust manifolds, throttle linkage, V-8 torsion bars are already installed, etc.

Thanks!
