Thanks for the photo of the drivers side rear plug Fishy68. That plug was not installed, but it is now. Still no pressure @ gauge. Pulled filter and adapter to make sure plug was in there it was. Spun the pump with filter off oil streamed out as soon as pump was turned. Check at gauge fitting oil streamed out also. But when line was reconnected no pressure on gauge.
If that galley plug was missing in the rear, then I would recommend to check for the two behind the camshaft thrust plate. You can see them in this how-to on the front end assembly of a small block:
