Re: Help with transmission selection
Good thread. Good site you found frnkeore.
I ran some different numbers for a 1939 transmission including a Columbia Two-Speed rearend with 25 and 26 tooth Zephyr gears. I set the max RPM at 4,000.
I have a set of the 25 tooth Lincoln Zephyr gears, a Columbia and 3.78 rear in my 32 roadster and love the combination.
