Re: What is it? Small Freeze plug??? 327ci.
I agree with others, you could try tapping your way thru but don't get wild, cly wall on the othe other side.
Could also use a bottom tap, run a short brass plug and forget it.
If no threads, you could clean up hole, insert a shallow dish plug, tap the center to expand and seal.
I would prefer to clean up and tap. May need this hole one day to drain water in block. Could also wait until motor come ever comes out.
