318 Motor Priming Issue

Thank you for all the replies.

First off, I didn't build this engine. I bought it from another FABO member, who said it was a strong runner, no issues, etc. So I have no idea if the bearings were lined up with the oil port holes.

Second, how do I tell if the shaft is installed either upside down or the wrong way around? What am I looking for?

I will try cranking it with the breaker bar instead of the ignition.

Thanks again
Most rocker shafts have a slot in one end. On the passenger's side the slot faces to the rear of the engine and down. On the driver's side the slot faces to the front and down. Some shafts do not have slots, so the way to make sure is to find the small oiling holes in the shaft. They should face down and toward the valve springs.
