carb replacement suggestions

I don't disagree with you at all, but whether it's a squarebore or spreadbore carb, you absolutely can over carb your engine. The engine will use what it needs with that set up, but it may still be more than it needs. Just sayin. He's already bought it so it's null and void.

I just installed a DC mechanical six pack setup that flows a true 1050 cfm or so on my 365ci sb it totally shreads the drag radials and revs up quick! I don't put much stock in that old cfm calculation better to use common sense.
