Is anyone out there with the 69 Dart this belongs to?

Is that chicken poop or has the block been welded on, push rod area, near the deck , inboard of cylinder 3 and 5.

Good question. I didn't even notice that. The block is sitting upside down on a rack behind 4 crankshafts now. Pulling it out is a PITA so I probably won't unless somebody is really interested in it or I decide to use it for something. I have way more engines than bodies for them at this point though.
