My guess would be a 307 Chevy. I remember the 2 bolt carbs but can't for certain say what it was on. Kind of like the three barrel carbs. I recall them but don't recall what they were on either.
looks like a mid 70's intake. had a 73 monte carlo, 350 2 barrel with two bolts on the carb, but my motor was red. that looks like marine blue boat motor parts..
I know you'all would have the answer. [cl I think I'll just put it back together and make it run then get the correct engine when I can. If any one needs a carb kit for a Rochester G2 I've got one I'll let go really cheap.
Thanks again for all the help.
