I have a 4 barrel carb I think is for a 1970 but not sure. It has in the small circle at the back what looks like 7043928 but vertically on the left middle section of the carb is stamped 7040502 with 1620 under it. Is this a Cutlass carb? Thanks

 

nope 70 chevy 350 auto california emissions

 

Great, thanks.
