Just looking to get a feel for what the experts are saying about how a motor should be broke in after a bearings and rings rebuild. What I am reading is 20 min @ apprx 1500 rpm, zinc additive to the oil (not sure what folks are recommending specifically though), and then basically a rinse and repeat (opinions differed after the initial 20 min it's too hard to pin point anything other than an oil change and run the sob).
