If I was to need an EFI setup, I'd use Megasquirt...Great expansion, and seems fairly straight forward to assemble and install. EFi isnt too difficult, but you need a bigger fuel feeed line, an EFI pump, and the return to the sump. Your kickdown needs to be modified, as it wont even come close with the beer barrel intake. The sensors and wiring arent hard, unless you're not familiar with what they do, and what they need to do their jobs. Would it be worth it? Not unless you're adding all kinds of boost, IMO. You can spend your energies on better things.
