Viking said:The greatest (most widespread, most innovative, just plain insane) cheating in NASCAR was during the '60s:
"It’s generally agreed that NASCAR cheating reached its high-water mark (or low water mark, depending on your view) in 1966, when Yunick built a Chevelle that looked exactly like one off the production line, but was actually one-eighth smaller, reducing aerodynamic drag and making the car dramatically faster."

In the old days, NASCAR was about having the fastest car that got by inspection, and being able to drive it around and through whatever and whoever might be in the way. Now it is about a handsome face and a nice backstory. I miss the mean cheating *******s.
