Thanks Ken
In further investigation, the paperwork that came with the engine said to remove electrical power to the engine, put in oil and crank engine for 10 sec and look for oil pressure if no pressure wait 30 seconds and do again until you get pressure.
I guess I built a pre-lube tanks for nothing. Also, the location of the oil access must be right behind the alternator because the only access I see is the freeze plug. The engine is a crate 2014 GM engine that Fran told me they make some changes, like the oil pan.
