Jeff,
I think I'm feeling the same pain. Craig's original criteria were:
"I'am defining the original motor or block as follows:
1. The one it was born with from the factory.
2. The one installed by Chevy Dealers such as Yenko, Motion, Dana, etc., that went to the first owner.
3. The one installed as a warranty repalcement."
I guess it would be difficult to know if an engine was the ACTUAL one installed in the original conversion....
