It's built by his local machine shop who is a good friend of his. It's big Chevy...over 632ci, runs a 139mm Procharger and is on alcohol. Another good friend of his works for Don Shumacher on top fuel funny cars. Alot of the the pieces in this motor are top fuel spec. They log things on this car that most people never think of. It runs a magneto for spark and makes around 3500hp. He's one of if not the hardest working racer I know.
