Bob, Here is a link about scoops that came from a thread I had started on Speed Talk.

It is interesting.
Also I had Vic Custer provide the scoop for my car & help with locating it over the carb. You might give him a call. Cell 936 552 4470 Shop 936 564 1615 Duane's Cell (son) 936 556 1891 He has a scoop design that works. That is something they do quite a lot of testing on Comp class cars.
