I really don't know the history too much. The frame does have a serial number. It is an old race frame that has never been used. The people in Utah that sold it to me 7 years ago had it for a while before I got my hands on it. I know about the ring and pinion that will allow me to run the engine in the rear. That just still seems like the wrong place to put an engine to me. Porsche begs to differ however.
