Hello Ron, RE: your post about Chet Herbert's twin cam two stroke motor, in the 70's Chet Herbert and Jim Tipke built a rear engine race car, Chet Herbert contacted Jim Tipke to build a chassis around the 12cyl. 24 piston two stroke motor. I am involved in the restoration of the car and am trying to find any information on the motor or talk to anyone who may have been around when they were run. We have a little bit of history on the car in that it ran as a supermodified in central California driven by Jim Pittillo, ran around 12 races then was outlawed. Any info would be much appreciated.
