Best method of making dual scoops functional?

Did the B body dual scoops go to the AC? Or was it just an "Air Grabber" setup that was plumbed in?

Af far as my 70 Swinger 340 it is just the open holes with a rubber gasket to divert water from running in under hood during rain.

Car would have had the unsilenced 70 style air cleaner in black wrinkle paint I beleive no snorkel on it. Mine was missing so I bought the repop 68 -69 style air cleaner and pie pan... it looks close but isn't correct. A friend years ago had the 71 Charger Super Bee with Air Grabber. It works the car picks up if you open that scoop at a roll...
