The ratios are all different but the overdrives come out the same.
As for mileage comps start with the sticker.
One of our members wrote a program to calc gear ratios. If I correctly input the numbers this is how their gear speeds compare.
1LE numbers are printed
SS numbers are penciled in
Min RPM was arbitrary
Max RPM is the published LS3 redline
