To All:
Does anyone know the CFM rating of the Rochester 2GC carburetor? Where can this info be found? Also, summit sells rebuilt carbs of different makes. Are the rebuilds good quality? Does anyone have feedback on this? Any help would be appreciated.

There are 2 sizes of 2G. The smaller was about 300 CFM, the larger about 425. Keep in mind, those were rated differently from 4-barrels; they are given at 3" of vacuum, where 4-bbls are rated at 1.5".
