I would be looking at pulling gear out to get the drive shaft speed down to 6500 at 160 and that will also help the pinion bearings survive for a long top speed run. It will take a lot of power to get to 160 even with the drag that a truck produces. Then there is the nut factor at speed with the poor aerodynamics and little or no down force.
