So, either they were all 3.55 or they switched from 3.23 to 3.55 early in the model run. For what it's worth there are some good reasons to doubt the accuracy of these charts because some say there was a 3.08 and 3.36 offered for special order with automatic trans and others say there were no optional ratios. another shows 3.55 as standard with or without AC but also shows a special order 3.55 that can't be ordered with AC ?!?
Regardless this was a stout car. I suspect that without AC and the 3.55 it might have embarrassed many a GTO with AC and 3.23's.
