sealing hood to Carb any HP gain?

----------------------------------------------------------------------------
Sometimes I have an overheating issue when I am running 90mph plus for 25 minutes..I bet I get alot of turbulence from the hood scoop and I read on here to seal your scoop to your carb for that very reason. The air entering the engine compartment can interfere with the radiator

I call that packing. You have two air flow masses packing in or fighting for the same real estate. Sealing the scoop may help the situation by limiting that high pressure air source.

It may also pick up some ponies from sealing. Not uncommon for drag cars to pick up MPH when sealed.
