UNTIL it gets oil pressure on the gauge, I would vary the RPM down low between like 1500 and 2000. Once it gets pressure on the gauge, IMMEDIATELY get the RPM up over 2500. Low RPM won't hurt it those first few seconds before it gets pressure.Oh, yeah, I slathered the pre-lube most generously;)
Bout 15 minutes. Only reason I say low RPM till it gets pressure is because slants are difficult to prime the oil pump. Without a prime, there can be air trapped. If it hangs up and does not get oil pressure in no more than 20 seconds, if you're at lower RPM, you've done no damage. But once it gets pressure, zing in on up to 2500-3500. I usually go on up to 4000 varying between 2500-4000. It's all about oil splash. That's the only way the lifters are lubed until it gets pressure. The lifters don't see any pressurized oil, all they get is dripping off the pushrods, and it doesn't get there for a few seconds.How long to I keep it at 2500-3000? rpms (if all goes well)
Those tiny bicycle rachet straps scare me, I guarantee they are nowhere rated for what you are doing, you need a good set of at least 2" wide straps.Got home last night, so nice to be home;) Killer6 had sent the correct engine support bracket!! Wow! Then I loaded the engine on the engine run stand on to my truck, then go to get belts at NAPA later today(didn't happen), I don't want to do like I did last time and buy a bunch of belts~ it was easy to load with my crane. hm, still kind of tired from the trip, did I mention I don't like traveling? I don't like crowds, airports, TSA, etc., so maybe tomorrow I can see about finish wiring the slant, then see what happens when I turn the key to start. Always kind of nerve racking to me.
ok, going to get Chewie, our mini-aussie.
be back soon

Nothing. Adjust the valves cold before you do the initial break in. It will be fine. Then you can readjust as needed. Opinions vary greatly on this. I've been doing this since 1974 and I have never and will never adjust valves on a running hot engine. Ain't happenin. I adjust cold and let it ride and I've never had an issue.Soooo, what do I do about the valve adjustments while the engine is singing between 25-3500rpms? Can I adjust the valves during this break in time?
You cannot do that on a slant 6. The oil pump is driven gear to gear directly off the camshaft.The fact that you were not able to get oil pressure bothers me. I use a drill and a priming "rod" that slips into the oil pump. I won't stop until the motor in the drill wants to burn up. Jus' sayin'. I'd go back and try again. Don't fire it dry.

yesAre you sure 1974?
Maybe you,but RRR, at 9 or 10 years old.
