Trust me when I say you don't need the 4bbl system. It is too much fuel and it makes driveability tuning difficult.

My boss has had his 2D Chevy 350 on his father-in-law's engine dyno and it made 320hp without any lean out problems. I also like my 2D, that I picked up slightly used for $500 from a friend who thought it was causing his backfire problems (timing issue).
