Is the rear main a dry sump or wet sump?

Sac,
Not sure. I would assume wet. I will check into it later this evening and let you know. How do I tell other than looking up the casting number on the block?

The rear main will have a provision to mount an oil pump on it if its wet sump, dry sump will have a smooth surface.
