What would cause this major catastrophe

Kurt:

Mistakes happen.

Did the tuner stand behind his work and offer to make good on your motor?
What's the story?

The reason I ask is because my neighbor has a '66 Jag that he just last week blew the motor for the 2nd time.
6 or 8 months ago, he dropped a piston, and had sent the motor to a Jag specialist for a rebuild.
The rebuilt motor made it about the same mileage that yours did before the oil pressure went to 10psi.
Some kind of debris lodged in an oil galley somewhere found it's way into #1 main and "bye bye bottom end".
The tuner asked him to ship it back so that he could inspect it and providing that the failure was related to the rebuild, he would rebuild it for free.
Seems like a perfectly reasonably thing for a tuner that wants to keep his reputation would do.
Of course all bets are off if the motor was incorrectly broken in, or abused/mistreated.
