This car was the spare car for the IROC 1973!
Here you can see the fantastic engine. Twin-spark, Bosch mechanical injection pump and the special small Fan and the High Butterfly Throttlebodies.
I found a Porsche powered Bug too!
Widebody and Top chopped with a 3-l engine, sounds great with his straigth pipes
Have a look on the engine
Porsche 956 in a line, pure racing history
