Yes it was to be used in NASCAR. The Ford one was to be the 427 "Cammer," a SOHC design. The idiot of NASCAR, I mean the President of NASCAR did say no to both. This is why NASCAR has become boring to me. They are stuck with all using the same platform which is not used in any street cars, the same displacement engines which are out of production beyond NASCAR, they use old 4-speed manual gear boxes which no one uses on new cars. Where is the fun in it if it is the same thing every year!? They need to let things be less even and let the best designer of a street car win like they did in the old days.
