Looks like I'm pulling the engine again. CONFIRMED, engine dead
Fortunately, I didn't have any glitter in the oil. Photobucket is down for maintenance, so I can't see if yours was shiny or not.If you're good at tuning, which you advertise that you are, give your supercharger a break and think about an L36 bottom end. You know the benefits, and chances are it'* cheaper than an L67 bottom.

Actually, I'm talking to someone about a rebuilt L37 short block. I then need to pulley up .3"
I do believe I have found the cause. Once photobucket gets back up I can upload them. I did a run out test on my flex plate. Speck has a 3 thousandths max. I found 11 thousandths in round, and 30 thousandths in warp. That'* 10x out of spec. I imagine I hit just that right RPM and it'* all over. I'll know for sure after I flip the engine and pull the mains. But after doing a lot of reading, main bearings sound a lot like rod bearings. My last engine I pulled all the pistons and inspected the bearings, but never pulled the mains. Now I wish I had.

OK, got some pictures now.
Engine ready to come out, again.

Say ahhhhh.

Time to test the flex plate.

Set the dial.

This was the high said, another part was about 8 or 9 thousandths below the zero. had a total warp of about 30 thousandths. Max spec is 3

Now to check center.

Total run out was about 10 thousandths.

Once again, a big hole where a engine should be.

Well, guess I'm ripping this apart again.
