I bought a core on eBbay just for spares. It must be a 66 or early 67 Rochester as it has the needle and seat that need to be held in be two small screws. I'd love to know what this carb is as the round ID tag is missing. It has the side entry fuel inlet and a C stamped on the TB so I believe it's a Chevy. 34924 is stamped on the TB and I believe that's a part number.
Air Horn Casting # 7032741
Main Body Casting # 7032720
Throttle Body Casting # 7034823
Any help will be greatly appreciated.
