Now that judging is over, I wanted to post a picture of the pad on this 1360 mile LT1. This was a stumbling block when I purchased the car as this code does not exist for any car in 1971. Many 1971 LT1's have individually stamped assembly codes and that is not at all unusual, but CBZ does not exist. The build code should have been ground off and restamped correctly as CGZ, but it was not. The pad sailed through judging as a factory anomaly. The engine has all of its original warranty gaskets and is clearly the original engine with a unique stamping.
