    It's about getting the intake above the stagnant boundary air layer.

      And it's about getting the carb out of the oven
      I upjetted a full size, front and rear, after cutting the hole, and sealing the carb to the underside. A full size; isn't that like 2000ft ? Anyway, that's what sucking hot underhood air cost me;

      I could but I don't know if that is really necessary since it only has ever gotten a few drops in it, but ya never know.:D

      Well, I see your point but figured more out going water capability would be better than not. And your initial drain size mention.

      The early hemi scoops were very flat, low,big area and hood hugging , they did force a little air in, we ran one for yrs. We ended up w/ a sealed snorkel because it was supposed to be the hot ticket, guess what no improvement over the 64-67 scoop !
      I have a friend that has a low 9 second vega, humongous prostock type scoop, and hasn`t shown to gain anything sealed or unsealed, go figure !
      I do have my 6 pack scoop sealed , (cold air). I used an old pizza pan, cut round and sealed w/ the moroso foam, to the bottom of the hood. I do have vents in the hood to let engine heat out also.
      YOUR RESULTS MAY VARY!

        I didn't bother with a scoop for my streeter, which seldom sees over 65mph. But I bought a nice oval aluminum air cleaner housing and mounted it on top of the hood, between the inserts.

          I had to run a scoop because the throttle body wouldn`t clear, even w/ a drop base air cleaner.
          I didn`t really want to, much like the roll cage, but needed the scoop, and the cage to stop the body from twisting . We twisted a 67 hemi belvedere body back in the day.

          I’m not out for the last 1% on my street car. But it held a lot of heat under the hood. Car never overheated, but it made riding it toasty. Put it in a friends garage and he commented how it heated up the garage. I made the twin scoops functional, just open into the engine compartment and I bet it lowered the under hood temps 30 degrees or more. Don’t know it it’s pushing air through or allowing it to be sucked out but it was a huge difference

          that is a bunch for that type scoop !
          I read a post on here a good while back, that the guy said those scoops were a joke, and wouldn`t pull any air at all. I had to add an extra hood pin in the back because it was lifting the hood at 128-130 in the 1/4. I think the front design of the car has a big big effect on it . .
