That would be my concern - thrust bearing damage. And that might not show up for a while, depending. I had a race motor lose the thrust bearing and ate a 0.100 groove in the crank, car ran the number every pass until one pass where it laid down like someone grabbed the back bumper. Pulled the motor down, it had over .120 of crank end play (started at .008) but what shut it down with the counterweights rubbing the main webs when trans internal pressure moved the converter/crank assembly forward and took up the slack in the engine. Had the converter looked at, it was undamaged and not ballooned, so the whole thing was likely some initial damage on the thrust surface that happened during extensive crank re-work before assembly. Took two race seasons for the problem to show up.
