Most converter builders furnace braze the pump fins to the shell , and weld anti-ballooning plates on the pump shell , and also on the cover . Also make sure you have some pull up on the converter to the flexplate , usually .090" is adequate .

Exactly what I was going to suggest. Happened to me once, with the same outcome (burned-up thrust bearing). The advice above is spot-on.
