There is much more surface area in the nose than the scoop. Thus more air pressure pushing in the radiator than in the scoop.
If you have a turkey pan or some other method to seal to the bottom of the hood, then the hood scoop will do what you think it should. There is no opposing air pressure in this situation.
Most of the OEM muscle cars had air boxes that sealed to the hood.

I just think that’s unlikely. This would only be the case if the engine bay were sealed, the only apertures were the grille and hood scoop. In fact the bay is totally open and the air passes in through both and out under the car and transmission tunnel. However, it may be that it causes turbulence in the engine bay and that would be a good research exercise.
