This is a nice set up for a cowl hood. Sealed cool air from grille area and hot air from engine exits cowl. I like it.
mine won't look that nice but it will be sealed to the hood. An probably won't be a "ram-air" type.

Scoop/pan design, air pressure and flow do weird things. A friend had a '65 Satellite with a carb pan sealed '65 scoop on it. Car had some inconsistency issues and threw a real curve ball once in a while. He cut away some of the seal, made vents, and the car was a lot more consistent. Can't recall if it picked up also.
That`s my point.........lots of fuel splash on carb top and although it does respond to jetting, 98`s in the rear and 84`s up ft. w/a pv seems excessive to me AND others. After talking w/Mike we thaught it would be good to even extend what I have now and see if the wide band responds.  I also thaught about drilling holes in the back of the scoop to release air.......something just don`t seem right and your buddy proved it by venting his.  Thankxxxx guy`s. 
Maybe its your air filter sticking up into the scoop and directly into the incoming air, creating a siphon on the bowl vents, maybe try a half round deflector on the front part of the air filter

what carb are you running & any chance you could post a pic of your set up with the filter top removed?

I remember speaking to John Bauman when he was the one doing the testing on the snorkel. Chrysler was very specific as where to place the carbs in relationship to the scoop in differet areas. Much had to do with maintaining fuel flow as well as ram air

I'll add this. I make alot of lexan boxes for hood scoops and we just cut a square hole in the cowl hood and let the lexan box hang out. prob 5 yrs ago when we made the 1st one it was sealed off on 5 sides front only open obviously. you could make a pass and I could see gas like it was floating/pulling out of the carb floating in the box abouve the carb. Drilled 4- 1/2 inch holes in the back of the scoop. Never done it again. don't ask me why. Just my experience.

Not sure if thjis will help, but I have experienced similar issues and found that a stub-stack solved the problem. We basically determined that different signals were being given to the carb at the bleeds due to whatever was happeing with the air in that compressed space at speed..the snub stack helped quite a bit...as a note we experienced this when the carbs were very close to the scoop...worst case it is a cheap experiment..as an alternative, open the back of the scoop ( drill holes / rais rear of hood etc.) allowing for a clean flow of air over the carb...maybe due both...
