Question about the large hood scoop on the SS cars

Chrysler did a lot of testing on the "mule car" Barracuda during development. When it was in private hands I had a chance to see some pics of it being developed & they tried IIRC, about 3 or 4 different designs. I love the scoop. But to be fair, it was later found out a "boundary layer" an inch or two above the hood surface was pretty much useless so the big scoop wasn't perhaps as effective as later designs. i.e. the snorkel scoop. Until the Demon Challenger came out it was the largest scoop Detroit utilized on a car.
