Another thing to think about... when you are traveling down the road in a rain... which way do the rain drops go... if up then its not gonna put air into the back of the cowl... the cowl itself is blocking the upward flow if its close enough to give the low pressure area needed at the back of it... so between the low pressure created from the intake/pistons and the cowl close enough it should get good flow.... I was gonna do a test on my car(P-Body) and a guy that was running a cowl.. we both had similar speeds but he blew up the engine and I never got the chance

Carbs are pretty much center of scoop and the front carb is about 3 inches from scoop, rear carb a little more clearance. There is about an inch and half clearance to windshield and carbs are not sealed to hood.

On another note. SS/AH do they seal their carbs or not to the scoop?

So does it run quicker sealed to the hood or not sealed?
I had a smaller cowl hood with a single carb and sealed it to hood and didn't make a bit of difference, now with the tunnel ram and two 4's i didn't mess with trying to seal the carbs on this hood.

FWIW...I used to run a six pack hood on my cuda. It ran about a tenth quicker and 1 mph faster sealed than it did unsealed. I switched to a 5" cowl hood, unsealed, and it ran the same as the sealed six pack hood. This was on a combo that I'd run for years. I have experimented w/ sealing the cowl hood to the carb but haven't seen anything really.

If you go down to the US Nationals and look at all the hemi cars, not one of them that I saw had there hoods sealed to the carbs.
