The wheels were sitting on hydraulic dollys that came through a translucent stage.
In front of the car was a regulation NHRA Christmas Tree that would blink down to green and the display sound system blasted the sound of a big block Plymouth going down the quarter mile!
The hydraulics made the car squat on launch, then lurch on the up-shifts while lights under the floor strobed from front to rear with increasing speed! Then at the end of the 1/4 mile the nose would dive under braking and cool air brake flaps would pop open on the rear quarter panel
