I have searched this forum for the size of the hole near the dizzy. The machinist took the plug out when he did the block and I want to use the hole for my pressure gauge. I realized I didn't get the plug back until much later. Engine is already in and I can't seem to get the right size. I know several have suggested using this hole for the pressure so if anyone has info I would really be grateful.
Also would it be pipe thread or machine thread if I am asking that correctly?

Ok, it is actually 3/8 NPT for those looking in the future. This part was what I ended up with so that the oil pressure tube fitting would screw right into it. Got it at ACE hardware with this part number LF3914406029802. http://www.whiteheadindustrial.com/p-293...4406029802.aspxWade
