The complete question was "And are you going to share your idea of why from the get go (1959?) why Nascar has never allowed hood scoops on "stock" cars?"

Then care to share what you looked up, and what you discovered, and your source, like a grown up?

You likely will find that "Nascar" adhered to the philosophy of maintaining a stock appearing car like the paying spectator drove in the late 50's, and hood scoops were not part of that look, I suspect the tradition took hold thru till today on hood scoops. Aero concerns of turbulence of air scoops was not on the radar back then in stock car racing. The cowl intake solution was a clever successful later work around.
