Likely running on alcohol with an engine like that. The car my dad builds engines for won the west coast nra nostalgia alcohol class last year. I grew up at the drag strip and that Camaro has always been one of my dreams. There is nothing like the smell of nitromethane and burning rubber first thing in the morning to wake you up.
I dont think he was running alcohol in this one, but I wouldnt doubt if he has something at his place that runs on alcohol. He has a few Lambos and other exotics as well.
