in case anyone cares...
I put on 250 miles today running the engine per my mechanics instructions, so nice to be back in the saddle again
Tomorrow will be another 250 miles and I'll be past the 500 mile break in (my mechanic did the initial 100 mile break in, which included an oil change, before I got my vette back). Then time for an oil change!!! The next 500 miles will be more aggressive but still cautious, and then it'll be time for some WOT fun

Leading theories;
Jason @ Katech; insufficient oil pan, oil pump, oil scavenge pump, for extended high G turns
stuck open oil pump relief valve, resulting in low oil pressure
(my personal) blocked oil passage preventing oil from getting to the bearings.

Not entirely true, I did have an oil starvation issue as that is why the engine seized; no oil lubricating the bearings, extremely high temps from two metal surfaces rubbing on each other (friction), equals failure. What I am trying to figure out is what lead up to not having oil lubricating my bearings.

The oil pump, scavenge pump, & relief valve all seem possible.
But I also wouldn't doubt that an oil journal could have been plugged causing that particular main journal bearing to be starved at the crank resulting in the failure / seizure of your motor
Speaking of which, it was just one of the bearings right ? Or was there more ......

I have seen 2 years of HPDE with Hoosiers and coil-overs with easily sustained 1.5g+ using the stock 06 oiling system with no problems. Prior to this, I had a C5Z that has seen 5+ years of track duty with Hoosiers and no problems. Maybe I am lucky or maybe the stock systems aren't SO bad.
If the LS6's oiling system, with simply adding an extra quart can hold up to 5 years of HPDE (with a 610' cam non the less), I think ANY car with a DRY SUMP system is going to hold up significantly better. It seems like the 09 design is just GM continually improving the Corvette to the next level, not fix a massive failure. Whethere you know it or not, GM continues to make changes to the Corvette that don't make any press. Some people think GM under engineers these cars, but I think the contrary, that they are over-engineered. I have seen many foreign cars that need quite a bit more modifications with regard to oil and lubrication than Corvettes to even think about running R compounds at a race track. The Corvette is probably the most well prepared stock car for this duty.
So, while the new design is surely better, remember when the 06 dry sump system came out it was praised as a major leap and improvement over the C5.
I have no scientific data to back my opinions, but raw experience of tracking Corvette's on road courses for a decade.
