70 Judge RAIV and V continuation

[Steve_Hoog]

Put aside all the previous debate of whether it came in a car or over the counter, my question is now "what is a production code doing in a RAV block?"

If we assume for the discussion that it is an untampered GM stamp, then why is it there?

It was suggested to me today during a phone conversation that the crate engines may have had a different holley carb and accordingly stamped in the crate as such. We are now waiting on verification on that theory from the owner of one of the motors.
