Unmolested LT1 Motor with 6000 Miles / CTB Coded

[TimG]

I recently purchased a '72 LT1 Corvette and one of the items that I had to clear up on the stamp was the one square "0" and one oval "O" in the build stamp. The same two types of "0"'s appear in the build stamp of the 6,000 mile car. I've been able to document these same two "0" in LT1's built in '70, '71, and '72. I also sent a tracing of my pad to the person that keeps the Corvette master pad library and he verified both "0"'s as typical UAW work.
I just thought I would add that since the same characters appeared in the low mile LT1 stamp.
