It seems to me the easiest way to get from A to B and do it the way your talking about is this. Hilborn and several other companies offer an EFI unit that goes on a four port manifold. Also they have EFI units that can go on an Hilborn or other stack injectors. Spend the money buy the parts and it's done just like that. No headaches and you can tune it with a laptop!
I guess the whole point for me was to avoid running those electronic pieces, but they would make it easier I'm sure. Anyone planning on mounting your pump on the cam like me, check out the remote water pump offered by Product Engineering . They said it will survive street use with its continuous-duty motor, and that it will flow enough to keep a blown gas engine cool on the street. http://productengr.com/water_pump.htm
