To help confuse you, a guy in FABO has dual FiTech throttle bodies on a cross ram, small block I think. He claims to have done zero tuning whatsoever. I haven't heard many issues with a slightly above stock build. Just a thought.
Ahhh, what about cutting up the fuel tank for a high pressure fuel pump? Or adding an external electric fuel pump? It is not as simple as bolting on a Eddie carb in 5 minutes. What do you gain except saying it's fuel injected? No mileage improvement? Hard to say if it is a drivability improvement? Not delving in too deep in fuel injection......yet, I just don't see the upside. And it's at least $1200 more than Eddie carb.
