Carb Question
How many CFM is a 1976 Rochester 2 barrel 2GC Carburetor. I've looked around on internet, but can't seem to find out any info on it. Any ideas?

Thanks

Re: Carb Question
race versions are 500cfm, so probably about 400.

Re: Carb Question
Thanks. It's a stock 2 barrel off of a 1976 350, so it must be 400 cfm.
Thanks Again
