With some aero mods, I think that the 3.27 would be doable on the highway given some consideration to lack of power on steep grades... however I can’t remember the difference in VSS location from the early years to the later ones... some are in the transmission and some are on the differential...

Why not go all the way up to a 3.08 gear and drop tire size to shed some rotational mass at same time? Run like a 195/65 tire?
