Put the "new" motor back together again. Decided to say screw balancing with my tools & background, just run it & see how it holds up. New HF crank with new ARC bearings is a bit tight, so I'm dropping to 0w-20 oil. Hopefully it will work. It's back running again, so we'll see how long it lasts. No high rpm pulls yet, still letting it run in. I was surprised to see the oil was still good after a change & sending it to Blackstone Labs for analysis. Had extra lead, chrome & aluminum, but it was still a good 5w-30 after all the abuse, heat & hard pulls from the desert. Posted to the web site with what I did, so you can see how it looks.
