Please see pic...

My new block seems to have a hole on the backside where I don't remember there being one on the block I just replaced. In the pic I am pointing at it. I know there is a oil pressure sending unit that is right next to the distributor, you see that location in the pic also just above my my hand.. I don't remember removing anything from this location. Can I just plug this with a brass fitting or is there supposed to be something else here?

Just leave it. No threads, how are going to put anything in it?

I know you all can't see them, there are threads. In anycase you all are right it isn't anywhere important.
