The donut was just a celebration at the end of a good run for his fan club. There is one training run and three runs, each 20-25min (if I'm correct). And the Ford-driver wanted to cheer up the crowd.
The `63 Valiant is an original Austria export car (built in Hamtramck). Now it's modified with a 360c.i. engine (300HP), rollbar, racing seats, four speed, racing suspension, and Porsche brakes.
