When I was just a kid, I bought a 70 Road Runner with an Air Grabber. I noticed that both rear corners of the hood, at the hnge area were bent down. I couldn't figure why that was until i had the car over 100 mph and could see the motor under the center of the hood. Then I understood clearly.

That scoop needs to be attached to the under hood bracing in as many places as possible. Just adding panel bond between the bracing and the skin is going to result in a distorted hood sheet metal where ever the panel bond holds the outer skin to the bracing, as the scoop is trying to pull itself free from the outer sheet metal. The shape of the front of the scoop isn't helping, it is creating a huge air trap under the front edge of the scoop.

One good thing, it appears the scoop is functioning well, its forcing air under the hood.
