Thank you both. I did not have a picture before disassembly and I needed someone else to tell me they are okay as is. You were correct in that they are 7/16 - 14. Bad eyes on my part. Thanks again.

Those were used at the factory for an engine stand.  No plug should be required.  The thread size would be 7/16-14.  7/16-16 is very unusual.

Nothing - they may be holes to hold the block for machining.  They do not go into the interior so they are ok as is.

I have two 292 blocks that I have had stripped, cleaned and machined. They pulled all of the oil galley and freeze plugs - a good thing. I bought and installed John Mumert's SPK kit for the oil galleys and freeze plugs. I have these two holes at the skirt line just above the oil pan on the passenger side that have nothing in them. The 1/4" plugs in the kit do not fit the holes. They are 7/16 - 16 bolt size holes. Wat goes in here? Thanks.
