I have a '77 Sout II with a 2 bbl holley carb. Problem is, the PO did an engine swat taking out a 304 and put in a 345. I also have no clue where to find the carb listed on the line setting ticket. So I'm wondering if there is a way to identify the model (whether it is a 2210, 2300, etc. ). Is there a way to identify the carb without pulling it off? FYI- I'm not real mechanically inclined, i know enough to ask the right questions most of the time, but don't have a lot of experience. Thanks for any responses.
