Typical component break-in is 250 hours.
Remember 1 sample does not make a trend ok? 1 sample is a baseline. I wouldn't worry too much about the Pb until one finds out what the elemetal breakdown of the Lucus oil treatment is, Pb may be an additive. Also, is this the first O/C since your intial rebuild? If so that is why your Fe And Pb is elevated.
Also, Fe and Pb are not the only metals associated with bearings. Cu and Sn (Copper and Tin) are also elements associated with bearings as is Vanadium. In fact, Fe, Cr, V and/or Mg make up M50 bearing material but Blackstone doesn't test for V but does for Ba? Strange. But I digress.
Typical Visc for Rotella @ 100*C is 15.6 Cst. The Lucus may have tightened up the oil to 19+ Dunno seems kinda high to me.
As for the High soot reading, It looks like Blackstone is using a the patch test which can be subjective to evaluate. A better test would be the FT-IR (Fourier-Transform Infra-Red) method. This isn't a knock against Blackstone btw as it is a valid test but it can be subjective. A simple way to perform this test @ home is to obtain some blotter paper form and arts & craft store. Out line or stamp a .50 piece or silver dollar sized circle onto the paper. Take an large butterfly paperclip or similar sized guage wire and dip 2" of the end into the used oil and remove. Touch the end of the oil soaked wire onto the center of the circle. Wait 15 minutes then look at the spots. Look for solids and poor dispersancy of the oil. Good dispersancy is a lacy-like spread.
If you are truely worried a TBN or Total Base Number test would confirm the soot. Rotella's TBN is 10 out of the can. A TBN lower than 5 would indicate the additive package/ acid fighting ability of the oil oil is done. Soot will lower the TBN and increase viscosity.
So there it is for what it is worth. I don't know where the soot could be coming from other than you didn't sleeve the cylinders and the new rings are only beginning to seat therefore allowing a small amount of blow-by past.
