Smokey Yunick, owner of Daytona's Best Damn Garage in Town, was a perpetual thorn in the side of NASCAR in general, and Bill France in particular.
Yunick was perhaps best known for interpreting what the rule book said—or, perhaps, didn't say.
In 1968, he said NASCAR specified how big a fuel tank could be, but he noticed no one said how big the fuel line could be. Instead of a half-inch fuel line, Yunick created a two-inch fuel line that was 11 feet long, and held five gallons of gas.
Another Smokey Yunick story: NASCAR mandated how much a gas tank could hold, which Yunick once circumvented by placing a basketball in the tank and inflating it with air. NASCAR checked the tank's capacity and cleared it. Then, when no one was looking, Yunick deflated the basketball.
