Not A T',
"actual" cfm on/thru a 383 cube motor (changes some but not alot with cam/etc)....

2,000rpm=163cfm
2500rpm=223cfm
3000rpm=286cfm

......5500=540cfm

I agree, time to try just the center carb...with 48* cruisin...for higher Hg

comment?:
at 13Hg, a carb is at the borderline for the gas not atomized by enough velocity, not suspended in the air for a good mix...
you will gain ALOT of velocity using only the center carb
