While I am no expert, someone once told me that while the 4.6l modular's
have similar displacement as a ford small block, they are significantly
bigger in just about every direction, and that is probably without whatever
space the EFI system would take. I think for the sheer amount of time
involved, that you could probably be happier with something based on a ford
small block.
I saw Theo's EFI system from Retrotech at SUNI and thought it was slick
system, I would probably go with their latest version if I was going to do
EFI.
The other one that seems to be popular with the Replica Cobra guys is the
mass flo system (they do a lot of advertising in that space), but that
system uses something like a standard carb based Victor Jr manifold that is
drilled for individual injectors and has fuel rails running above them,
which I don't think looks very period correct.
