BluePrint 347 in and secure! Quick question on hole near the starter

[Big Blocker]

I have to disagree with what was stated above - there are NO oil galleries down that low in a small block FORD. That is NOT an oil pressure port.
IF the hole goes all the way thru the block, it could [possibly] be a water jacket drain hole but I'm wondering IF it goes all the way thru. Water jackets don't go that low either. Test it with a 1/4" bolt or a small piece of wire and see if it bottoms out about 1/2" in.

I agree, never known a Ford block to have an oil port there. I thought drain plug, but Doc has a point that it is too low?
