I haven't done it yet but I'm planning to rig up something like what you have in mind in my GTO. I'm going to modify an air cleaner base to run to the firewall and draw air in from the cowl. This is a high pressure zone at speed and unlike the hood scoop, will actually provide a light ram air effect. Here's a picture of Jim Hand's wagon using the same thing with two ducts.
Jim Hand's son is a member here; Tom Hand. He had a cowl induction setup on his 69 Barracuda 340. I think there might be one on his brother?in/laws? notchback that was in Mopar Action years ago also.

Nice. So, where exactly does this system pull in outside air from, the front vent valance? Looks really nice.

Remember, the late 70s aircleaners are set up for 3" flex tube already, so get 2 of them and put the snorkel from one onto the other. I did that with my 77 Cordoba when I was 17 (gosh, 20 years ago!).
Didn't notice any performance improvememnt, but there are lots of jetting, etc variables to investigate (which I didn't know how to do back then).
There’s an Aussie magazine website that did some investigating on this regarding using a pressure gauge and tubing at the front of the car to determine optimum placement of scoops. Do a search for ‘negative pressure supercharging’ or something like that.
Parts I seek:
driver doorpanel, 65 Sport Fury, prefer black, needs to be 7-8 on 10 scale, might buy set
16" x 6" Dodge truck wheel(s), from early 70s?, takes 9" dogdish - need for a research job so cheaper is better.
69-73 C-body caliper brackets and/or splashields
Send a PM.

not to steel the thread but how did you build the part surrounding the air cleaner or where are they sold.

if you replaced the Corrugated duct work with a something smooth your air flow would be much better.

No matter how nice it is done or comes out, I really dont think there is any advantage to it myself. It just adds junk under the hood of a nice car.
I put one of the dual snorkle 'Ram Air" units on a 440 Cuda back in about 2000-2001. Sealed the top cleaner lid (they use a standard 14") and routed the two 4 inch ducts through the radiator support. (Battery was already in the trunk and no washer bottle so plenty of room) Car had a solid .25 second 1/4 improvement with NO other changes.
It worked for me, definatley. Looked great too.
