Is this the CK Spurlock car? I have a color copy of that around here somewhere. Years ago I was told that per Tonowanda records there were 7 L-72 Camaro coded engines shipped to the LOS plant for production use. There was a second possible LOS built COPO that popped up about 6-7 years ago with a CBC and it was similar to the Spurlock one but more complete, and only a few numbers off from that car. I think Alan knows of that car..............RatPack.................
