Was it possible to order any ratios other than 3.55, 3.73 or 4.11 in 70-72 on a LT1 car? I've heard of, but never seen, 4.56 on a ZR1. But was it possible to order numerically smaller, 3.36, 3.08?

Re: C3.. LT1 axle ratios
Bruce:
In the '71 Dealers Sales Album, it shows that the LT-1 ordered with the M20 trans could receive the 3:36 ratio as the economy one (ZQ8 code). If ordered with the M22 trans, could receive the 3:36 ratio as std, and 3:08 ratio as economy, at extra cost. Neither of these ratios are shown to be available with the M21 trans, just 3:70 as std, 3:55 as economy (ZQ8), and 4:11 as performance (ZQ9).
Can't speak to you about the other 2 years, sorry.
