Hi everyone, I'm not sure what year Chevy quit offering a dual quad setup on their sbc, but I believe they started in 1956. From 1956 to when stopped, what carb. could you expect to find on a dual quad setup?? Rochester 4GC or maybe a WCFB?? Were there any others?? Was this setup offered up until 1961 on the Corvette?? Just wondering. Thanks, Carmine.
