For what it's worth, I have a few big block Corvette pads with the same HD rebuilder stamp and rebuild date. I've traced this builder to Kentuckey. He always stamped his initials and date of rebuild, probably for warranty reasons. All the engines I've seen this on have been Hi Performance big blocks.

Thanks for that,makes sense since the auction says the car sold new in ky.

I’m not an expert by any means but that mn stamp is definitely different than a
Couple of my original Mn blocks. The M forsure.

Did they use different stamps throughout the year for these blocks ?

Yes there were a couple M's used
