Re: Carb size for stock 350?
The quadrajets primaries are even smaller than those of a 600 cfm carburetor. That is why it runs better on the street than any 650 ever will ! 90% of the time you only use the primaries ! When you go to full throttle your secondaries kick in and you can have up to 750 cfm. If your car was a drag only car, I would say go with a 750 Holley !
Save your money and rebuild that Quadrajet !
