The initial fill is generally kept in for a very short interval (less than 100 miles), then swap in some new oil (conventional) and a filter, and drive on it for ~1000 miles. After that, your break-in period is over; run whatever you like.

During the break-in period, you want to be doing pulls in boost and then engine braking.

If the oil pump wasn't packed with grease, I wouldn't bother turning the engine over without spark/fuel. I find there's not enough RPM from the starter motor alone to pull oil up into the pump when it's not primed. Fire it up and get it up to about 2000 RPM; you should see the oil pressure perk up almost immediately. The assembly lube will do its job.
