I have a set of racing cams that I removed from my gtv6 so I could get it to pass CA smog. I was told by the guy I bought the car from in 1999 that they were Auto Delta purchased in the late 80s or early 90s, but Phil Mason thinks that they are Pittatore. They are in near perfect shape with no flat spots. Not sure what to ask for them and not sure what markings would identify the manufacturer. The lift is 11mm and will not pass California smog.
