Bless you TechInspector.

I've been arguing this point for years and I usually get the old carb-size with VE tossed at me.

For street use, Skids72 comment on good atomization probably applies, but perhaps not.

I run a single 750 Edelbrock on a 462" and at part throttle - meaning light throttle in the 2400# Deuce roadster - and subjectively viewed, vaporization is probably doing ok.

Over at "GoFastNews" I think they have an upcoming article on running a huge by large carb and initial reports are it's doing ok.
Not sure if it's strictly for racing or street running as well.

Little brother runs a pair of 1100 cfm Dominators on his 500 cid DRCE engine and the car has good manners at part throttle operation - which means he's pretty much running on the idle circuits.
The car, an about 2500# Henry J tube framed drag racer.

Going the other way I've run a 600 cfm smog Holley on the 32 with the 462" Buick engine and it ran well.

Interestingly, mileage was about the same.
