RE: Rear end ratio ?
If you look around on here , rawze has posted a calculator several times that will tell you the rpm at which speed depending on ratio .
Personally I would gear it to run at 1650 at 65 mph if thats what you like to run at .
But thats just me ...
3.90 would be about 1500 rpm at 65 I believe.
I also had 18 speed in all my trucks though , I did have one 15 speed actually.
