Aren't 4bbl carb CFM ratings kind of like 'gross' HP?  sort of unrealistic?  
I don't know this, but that is the idea that I always had.  Doesn't a 350 
with 100% VE flow something like 550 cfm at 5500rpm?  Most 4bbl carbs start 
around 650cfm which would be pointless if the two numbers really correlated.  
Apples and Oranges?
Just wondering,
Ted
