I saw an interesting "foot note" on history in this months "Hot Rod" magazine. Yeah, I know I'm an old fart but I still read that one,
1965 was the first year in NASCAR history the racers started to think seriously about aerodynamics. Narrow bumpers, door or window trim removed, etc. 1966 was the first year NASCAR officials came out with a body template to get a handle on things.
Peter Brock was SO far ahead of his time it just blows me away!
