The point I was trying to make the ports flows so bad that stock I'd have a hard time believing you hit 200 hp, and with mild cam 4 bbl and headers I doubt you'd break 175 hp without head work.
I know 225 ain't exactly half of a 440 but close
And yes 4bbl and 2 bbl are rated different cause there measured at different vacuum levels 1.5 and 3 respectively. And a carb actually peak cfm is dependent on how much vacuum there is at full throttle. So for a 4bbl under 1.5 would have less than rated cfm and above would have more. Just the greater the vacuum level the more hp your losing to pumping loss. To go with another discussion on another thread about carbs, a 1050 cfm carb on a engine of .5 vacuum would be actually flowing way less than the 1050 cfm
P.S. six packs aren't really flowing over 1100 cfm probably more like 850 cause of the whole 4bbl 2bbl thing.
