If I have the engine out of my car, and have seated the torque converter on the input shaft of a small block 727, how much "wiggle" should I get if i push on it near the edge of the flywheel? should it move at all? if it is seated, should it sag so the teeth are almost touching the bottom of the trans case?

Just trying to guage if i have a bad converter... was getting some heavy vibrations from it at around 55mph.

TCI 11" breakaway with 2400rpm stall if you'rre wondering.
