My Fords have various though smaller. They are oil galleries. They are supposed to be pluged. Mine have nice stainless steel plugs.

That one goes into the oil galley. Should be a couple on that side. There is a water drain on the rear side of the oil filter housing and a plug higher into the water jacket.

A bracket that holds the oil pickup tube from the float to the pump is bolted to the block there. Threaded hole for a 3/8 bolt.

Oil galley is on the other side of the block.

Your comment is what I was thinking , has to go with the oil pump. So is these threads on the inside of the block ? On the out side its smooth , no threads. Just like there should be a plug in this side. U can see a pin inside the hole.

I am pretty sure that originally they are driven in but the rebuilders tap the holes for the various sized plugs that they stock.
