A High Boy or Hi Boy is a fenderless car with the body still at the stock height on the chassis.
Greg's car.

Further back there was mention of the V12 Allison dragster at the Sprint. Here is the same car taken a few years ago part way through a restoration by Garth Hodgetts. I have some more up to date photos, but blowed if I can find them.
