Cheating isn't very prevalent in today's NASCAR, and it would be very difficult for a driver to get away with blatant cheating. But that hasn't always been the case, and drivers and mechanics had the ability to get away with bending the rules in the past.
Tony Stewart was a guest on the Dan Patrick Show, and Patrick asked Stewart to reveal the best cheating story he had heard about during his career.
Stewart recalled a story involving former NASCAR mechanic, car driver and occasional driver Smokey Yunick. He said heard that Yunick took a car and made it smaller while keeping the motor the same size.

"I think Smokey Yunick, and what I remember of the story was that he built a car that size-wise was 7/8ths of the original size of that brand of car. But he was somehow able to make it smaller to where it was more aerodynamic but still had the same size motor," Stewart said.
"The art of cheating 20, 30, 40 years ago was much more cool than what it is now because there were so many things you could already do, but there were things they went way above and beyond. Like I said, there's nobody in our sport right now that would even have the capability to take the car and shrink it down to 7/8ths of the size it's supposed to be and not get caught with it."
Here's Stewart with Patrick discussing Yunick.
Stories like that were probably more frequent in the older days of NASCAR, but it's hard to imagine any driver getting away with that now.
