340 Engine Priming?

Hello I just had my 340 engine rebuilt for a resto im doing on my 72 340 Duster, I need to know the proper way to prime the engine before I start.
I have made a shaft to fit into the oil pimp but not sure what way to turn it and for how long etc?
Any help thanks.

I got a 360 on the engine stand and kind of wondering the same thing. I know you turn it clockwise as this is the same as the distributer turns. I read in a Mopar thread somewhere you turn it for at least two minutes. You will feet the drill die down some as it starts to pickup the oil. I'm thinking about doing it while the engine is on the stand and then do it one more time before fire up. I would like to hear others replies also because I have never done it myself.
