I would normally ask Phil (Throttle Crazy) or Brendan (ronsfriend) but since both are gone I figured I check to see if anyone knows. How do you prime a fresh engine before the first startup? I've only built engines that have oil pumps driven off the cam so I've always been able to just prime it with a drill motor and something to slip into the pump like an old distributor. How do you prime an LS?
I spoke to Phil last week about this and he said that's what he did when he was building engines at the dealership. He'd just crank it over until he saw oil in the head.
