Dart 340 twin hood scoops

Looks only as mentioned. Google Boundary Layer.

No positive function as far as performance on the cars.

They do allow the compartment heat to escape!

Funny about the 69 RR. Dudek with the FAST Hemi Runner was searching for at least one 69 that left the factory WITHOUT an air grabber set up. So he could rip that junk from under the hood.
