Hi All,
Sorry couldnt post a pic, but if you have a look at some web pics of original 427 street cars, like Bruce Camberns CSX3170 as an example, there is a horizontal panel in the center of the radiator opening.

Looking at other originals, some times this panel is angled up suggesting that it is a deflector.

Does any body know more info about these ? was it to reduce flow to the radiator for cooler climates or direct air to some other vent purpose ?
How was it adjusted ?

cheers to all
Dave
