Crank Thrusting Foreward Issues

Thanks for all the advice guys, much appreciated. I'm gonna have to take the pan off and check it out. I built the transmission so I understand the fundamentals of the pump and converter. I can't say for sure if the converter came out of the pumps' slots or not and was forced in, nor do I remember having to pull the converter fwd to start the flexplate to converter bolts, but I have a feeling the install was uneventful. Next time I will have to document everything thouroughly. I'm no stranger to a mopar engine build, this is my third, I can't see why i wouldn't have checked the crank end play after torquing the caps down. I have all the tools. It was about 2 years ago. I won't be able to take the pan off for a while but I will follow up to report the diagnosis. Thanks again fellas!
