I didn't own the car at the time the first 2 engines died.
Lupe (Roz 1999 SVT-C) just lost an engine due to a spun bearing. There is a post in the 3 liter forum, maybe you could ask?

I have seen numerous posts about the 98's having spun bearing problems but have no technical knowledge on the subject. I just like to drive fast.
