Greetings. Just joined CAC to try and get smart on C-3 (1969 - 1972) Corvettes. Lots of hard to find knowledge here. Have had numerous Chevies all with small blocks. Planning on buying a C-3 (1969 - 1972) small block coupe with an automatic so the wife can drive occasionally. Question is - did C-3 Corvettes have both Turbo 350's standard and Turbo 400's available as an option (M40). Reason I ask is that I have a built 350 engine and GER brand rebuilt Turbo 350 sitting in my garage that I plan on swapping into the C-3 that I buy. I will keep the numbers matching engine and transmission. I see C-3's for sale but always seem to have Turbo 400's listed as the automatic. I know that if I buy a C-3 with a Turbo 400 I would have to swap the yoke and install a manual kickdown cable on the carb. Any clarification regarding Turbo 350's in 1969 -1972 and suggestions regarding the engine/ transmission swap would be appreciated. Thanx in advance. Respectfully.
