How much power will it make?

Never saw that EFI kit, but those are pretty cool. Don't mean to derail this thread, but wouldn't that be a performance hindrance, though, by delivering fuel through the carb inlet, and not somewhere closer to the cylinders? I can't see how it delivers into each port, but I'd be wondering about the atomization collecting on the walls of the intake manifold and not delivering as efficient a mix of a/f. Am I just crazy? The kit has some killer reviews, I don't question that. But might anybody know a difference between a standard EFI kit that utilizes injector ports on the intake manifold?
