You didn't by any chance put anything on the back side of the bearings on final assembly? Anything?
That sounds good enough to me. It's been a long time since I had a chance to inspect some low mileage bearings but I am always surprised how scuffed up they looked after only a few miles. I have never taken out bearings that looked pristine and new. I kinda think that's how they break in/wear in. I have always used the red slippery assembly lube since the 80's, can't remember the name of it right now. I think you might be ok after all.
Main bearings on the crank out of round? How did the old caps look like?
The caps look good and I just re measured all the bearing clearances and they are at .002. I'm thinking about running them. Anyone think I should get new ones? Also just to try something new what's everyone put on their main and rod bearings when installing?
Those pictures of the bearings in the block look very dry and clean to me.
NO way I could make my bearings look that oil /lube free unless I took them out and solvent cleaned them and solvent cleaned the block as lube will be dripping on stuff.
I want to know what lube you used and did you clean it off for the pictures???
I use driven assembly lube or Lucas or the EOS and sometimes just Gibbs BR oil.. never an issue with any of it but it leaves everything oily. My bearings look like new after a few turns.
I think your lube is poor.
Buddy used WD40 once..Parts store told him he did not need anything on the bearings.
I did clean them off to better show the wear.
For an engine that’s never been run?
Yes never run
I'd think about sending it out to be line honed & get the crank checked for straightness.
I had one like that but it was run, took it down at 15000 miles copper showing in some places on the mains.
The wear pattern looks within reason, and perhaps turned too many times on the dry side. If you could turn easy by hand with the mains TQ'd down you will be OK.
IF you can, set the lower mains in place only, lay in the crank, and toss a dial indicator on the middle main (3rd) it will tell you the run-out if any, repeat on the others to see what comes up.
