the transmission wouldn't matter much here...it'd be your rear-end gearing, and how much RPM you can turn.

Final drive is one to one, just like every other non overdrive trans.

Engine RPM and Speed are determined by the rear end ratio and tire size.

t98

I have a stock Dana 60 rear end and 33" tires
1961 f250 4x4
I believe the rear end has a 4.56 ratio

Be prepared to crawl! I have the same trans with a Dana 60 4;10 I am turning close to 3 grand to run at 65.. so you will be turning probably just over 3 grand to do 65

Your combo gives you 22 mph per 1000 rpms in 4th.

Stay in the right lane please.
