What do you think happened?
For this kind of damage you would think an oil pressure warning or light would have shown.

I'm not sure but would anticipate it might be related to an oil pump failure, as mentioned previously. But I'm also curious if there's any damage to the bearings in the SB.
I can confirm the oil pressure in the past 5 motors I've had in my car has ranged b/w 20-30 psi @ hot idle, with the sensor plumbed in by the oil filter. This includes the OEM motor before I pulled it, as well as the 4 motors that I've built over the past few years. My current motor has the lowest pressure, since it has the most bearing clearance but it's usually around 22-25 psi @ hot idle, this is with crappy Castrol 10w-30 dino oil that I'm using to break in the new motor. I will soon switch to DT40 Driven 10w-40 which will increase the pressure a bit.
