novak sez 6.55/3.58/1.70/1.00
AA sez 6.58/3.58/1.57/1.00

which one is it? :confused:

Pete,
SM420 (H) 7.06/3.58/1.71/1.00/6.78 R GM '48-67
SM465(MM4)(H) 6.55/3.58/1.70/1.00/6.09R GM '68-90
Don't worry about minute discrepancies. I've seen the same trans ratios rounded up and down to the nearest 10th. AA has a lot of wrong numbers in their catalog. I have a list of 161 manual transmissions and their ratios and applications if you want.
regards, as always, jefe

ah thank you. i'd really appreciate it if you could email me that list.

thanks again :)
