Highly, highly unlikely other than some totally non-related gremlin. You say "...when it was time to hook it to the torque converter..." Does this mean that you've got the transmission in place, sliding the torque converter forward to bolt to the flex plate? It may be a hassle, but I'd drop the tranny, then remove the flex plate and put a bar on the dampener retaining bolt and see how it turns, even measuring the torque if you have an old deflection beam torque wrench, then re-bolt the flex plate paying close attention to any interference and confirm it's not the flex plate binding on something like top of bellhousing? There should be no change in the rotating force with the addition of the flex plate.
