Every Grand National Car that started the race received a certain amount of money just for completing the first lap of the race. Bill Champion's engine builder once told me that they would wrap a steel wire around the oil line and tie the other end of the wire under the dash. "Champ" would complete the first lap and then switch his engine off, then yank the wire from under the dash spilling oil all over the track. The race annoucer would come over the public address system and annouce "Bill Champion has just blown another engine between the first and second turn."Of course his engine was fine and he collected his money for starting the race.
