On the 1965 Hemi Belvedere with a factory scoop it picked up two MPH placing the factory plate on the carbs sealing the carbs to the hood on the first pass with the plate. I know in 1972 John Petrie decided to copy his 65 car and put a cookie pan on his doms on the1972 Cuda and it picked up a few MPH and some ET. Next time out most people in Pro Stock started to copy him. The scoop was a Shoe box type old pro stock scoop. I would say some work and some do not. You have to experiment to see why some things work and some things do not.
