Default Trouble decoding block...

I'm banging my head against the wall, trying to figure out the block code on this old engine. I know the suffix is supposed to be 2 or 3 LETTERS telling you what the block is (350/327/302, etc).... but this block's suffix code is one letter and two NUMBERS!??!?! What the hell is that supposed to mean? Anyone have any ideas? I already know it's a "010" block (Casting number 3970010)...

I make can make out "H64"... the rest is pretty hard to read, because some MORON decided to deck the block in the past.

That looks like a rebuilder's stamp to me, not OEM.

Now that's interesting! Why would a rebuilder stamp a block?
