I remember that a 1971 Superbird was actually designed and produced. The wind tunnel test is on line. I think it was Richard Petty racing. I know the 426 was no longer being used because it was TOO fast and Chevy cried to have it outlawed from Nascar. The 71 had a 305 v8 in it. Can anyone tell me what that was?
