Question about the large hood scoop on the SS cars

Certainly Chrysler did a lot of testing on those cars, but is there any known evidence that the large hood scoops on these cars really helped? Not that the scoop does not look tough, it does. It also adds a lot frontal area and wind resistance.
A Hemi running two carbs on a cross ram manifold is going to suck a lot of air and the surface area of the scoop is large so it does not seem like it would ever be pressurized if the goal was to add some passive air charging.
I understand the need to bring cool air into the motor, there are less 'wind resistant' ways to do that then the large forward facing hood scoop.
Also the cars of the same era, when running injectors would have the velocity stacks through the hood with no scoop.
The large hood scoops were ran for a reason on the carburetor cars, why?
