2BBL vs. 4BBL

I have a 2BBL on a stock 350 engine. I am thinking of putting a 4BBL on it. What benefits will I gain with the 4BBL carb, also how many CFM should I be looking at. I am thinking about 700. I plan to do headers and exhaust now and thinking of a mild cam in and bore it out .30 over.

 

750cfm q-jet was stock for the 4v..you could use a 800cfm q-jet off a 455..
my personal experiance, don't go with a 750 speed demon, it'll hold you back.. some people recommend the 750 holly double pumper.

good luck with the conversion!~

 

I have an aluminum Poston S-divider intake, rebuilt 750cfm Quadrajet carb and a 1" carb spacer for sale if you are interested. Shoot me a PM.
