The pits area is pretty relaxed and you can generally find someone that will talk to you about their car and class. In 1998 there was a team running a 1941 International truck with a 16V 92 on the frame behind the cab. Essentially the back of the cab was the radiator with a duct through the cab taking cool air to the radiator. He got into the throttle a bit hard at 150MPH and spun out. Belt drive gave it pretty much direct drive in top gear.
