On a large enough engine, with a big enough draw, who is to say it won't pull 3 inches? or even more? If it does that, then the 1350 capacity is now reality. I would say on a big enough engine, with cam, and high rpm, it should be possible.
So what is the point of the discussion? to talk theory, or application?
It doesn't work that way.
The carbs are rated for flow using specific pressure differences across the throttle. A high vacuum below the throttle will draw more air.
The 2 bbl got its rating with a higher draw. That means you can't compare the numbers directly with a 4bbl.
If tested like a 2 bbl, a 750 CFL carb would get a 1050 rating.
We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind.
