2bbl Rochester

[JasonB]

How many CFM is a 2bbl Rochester? I've heard there were 3 different versions. It is on a 1976 888 (ford 302) Mercruiser.

I don't know for sure what the CFM rating is but I found this list that might help you determine which it is by measuring the venturi...<br /><br />Rochester 2GC carb specs...<br />1-3/16 venturi = 352 CFM <br />1-1/4 venturi = 381 CFM <br />1-5/16 venturi = 423 CFM <br />1-3/8 venturi = 435 CFM
