Yep, purely for show and not go. This is one area where Chevy had a better design. Chevy took advantage of the high pressure area at the base of the windshield in the form of cowl-induction. This is why the 2nd gen had the scoop facing the windshield. The RA hoods don't provide that much more boost due to the location of the scoops. And, this why the scoops on 69 T/A are near the leading edge of the hood where there's another high pressure area.
