LS Swap Question

About to do a LS swap in a 78 k30 crew cab shortened with the following drivetrain: 2002 6.0/4L80e/np205, Dana 60F/14bolt rear.. Plan on running about a 33 tall and skinny tire.

Trying to figure out best axle gears, to have optimal room's st 70mph cruising speed. Just not sure what this motor/trans likes?

Thank you for any help you can provide
