The flywheel cover goes there. A 2 piece arrangement made of sheet metal. A dish shaped pan on the bottom called an underpan and a slightly v-shaped piece on the front by the oil pan called an extension. I would post pics but I need to get on the IT Short Bus. The hole is for timing. It should have a stainless steel pointed pin in it for setting the timing with a timing light. A rubber plug can go in there but it isn't necessary. Chevs of the 40's sells them.
