so i checked my 2gc 1.080" :( How many cfm is that?
i guess i won't be doing any racing with it.
this explains why i was amazed at the power from a 2gc, i was thinking it was like mine. LOL
my holley 4bbls(primary) are at most 1.2" 4011 and 1.193 4165

tame a lumpy cam for the street, more street torque! see my article, archived in the waybackmachine.

sounds like you have a small base 2G carb these flow 278cfm, good for a 3X2 set up,4cylinder or small six, I was thinking of trying one on a motorcycle a while back
