Unless you are already going 160mph and shift into 6th gear - at which time the super tall gear will have the car slowing down no matter how much throttle you use. The stock LS6 just does not have the power/torque to accelerate the wheels through 6th and still have enough oomf to move the wall of air aside.

I added a little into your response, in case someone sees that as a variable.

Yes ... RWHP, aero drag + rolling resistance and gearing (which determines RWT and tangential propulsion force at the tire/road interface) are all factors in a force balance equation that will determine the "drag limited" top speed at WOT. This is a little more in the rocket science domain.

Seems like RPM would have nothing to do with aerodynamics. At a specified speed, the wheels are turning a certain speed. The engine speed is directly related to the wheel speed, so it would not change unless you are getting more slippage between the tire and the road surface.
