3G Hemi fuel: EFI vs Carb

I think the 280 hp engine was a magazine (Car Craft maybe?) crate motor swap straight from Mopar complete with their crappy intake. Although once you figure in the drivetrain losses you aren't really doing all that bad. A 20% loss puts 280 rwhp at 350 at the crank which is pretty close to what it's rated to make anyway. The Mopar and XV carb intakes are pretty reknowned for cutting horsepower bad, not necessarily the carb's fault. The Indy intake has been dyno tested with headers and a TBI system (essentially a well tuned carb that adjusts on it's own, but distributes fuel at the same location) at 400 crank horsepower, but I've never seen a straight comparison between the carb and EFI versions of it (exactly what I did on my car) which is what I would really like to see. I've not heard numbers on a stock type Edelbrock dual carb setup either, HemiJoeJr was about the only one I've seen use it so far and he's not exactly stock.
