Thank you Gdads51! Just what I was looking for, and a lot more.
The gear ratios include 3.31, 3.55, and 3.70; so close to what the
online comments were suggesting. Close enough for me anyway.
I assume 3.31 would use lower RPMs at highway speeds, and a
3.70 would yield better acceleration, with 3.55 being an in
between compromise. I'm wondering if all of this implies a one
speed rear end instead of a two speed rear end with a power
matic transmission? For a driver, not a heavy hauler, what gear
ratio would anyone choose? Thoughts? Now, where would a
person find a powermatic? They were made at least from 1956
through 1960. Thanks again!
