What manual transmissions and gear ratios did the 70 LT-1 come with?
Trying to determine whether a 1970 LT-1 convertible could have come equipped with the M-20 and/or M-21 manual trans, and what rear-end gear ratios would have been available with the manual gearbox in that same LT-1 car.
Hello 70vette-- Yes, the 1970 Corvette came with either the M21 or M22 manual transmission, although a mere 25 of the M22s were sold. The rear axle ratio was 3.55 with the heavy-duty M22 and 3.36 with the M21. I knew that right off the top of my head (you can check if you want.) Contact me if you have any further questions. Good luck from Bovan.
