Default Minimum requirements to start up a 5.3l

Kinda my first post here, but LS1Tech has already helped me spend quite a bit of money in the classifieds. Regardless, I've got a 240SX with a freshly mounted 5.3L in it. I've changed how I'm doing things and now don't plan to have the vehicle done by spring as I have some sheet metal repairs to make. But, I would like to run the motor to test that it does run and I don't have any other repairs to think about. so...

What's the minimum I need to do to get it up and running at least to verify that it does work? It's from a 2005 and I have the full harness from the donor silverado, pedal & TAC, MAF, so basically everything I can think of except O2 sensors, intake to oil pan and headers. I don't have a radiator at this point so I didn't know if that would be a problem.

Thanks,
Brooks

You're good for up to 5 minutes of idling and mild no-load revving without the coolant circulating.

You don`t need O`2s. You will get a check engine light, but it will run.
