Cubic Feet Per Minute (CFM) is the same whether it's a 2bbl or 4bbl, that's what the carb flows. It makes no difference if it's a 2bbl or 4bbl, the CFM is what that carb delivers. There's no difference in the 2bbl or 4bbl rating.


Nope

the 6bbl would be rated at about 810 cfm if flowed the same as the 4bbl. Better distribution is what made it shine.
