I would find out what a C5 or C6 Vette has for trans gear ratios. Gotta figure GM knows the best gearing for a 3100 pound Vette. As long as the ring/pinion in your G50 is close to the Vette rear end it should work fine. If I recall a Vette can reach right around 60 in first... Imagine your 0-60 time with that ratio
