I understand on the top of the chevy blocks (BB's) they had a unique machine cut pattern (I believe its called a broch mark). To the best of my knowledge this cannot be reproduced as of now.

Does anybody have a photo of what this machining pattern looks like?

No offence but I have a feeling this is a question that few will answer and probably for a good reason. Best to leave this sort of info out of the hands of disshonest individuals faking thier cars into something else.
