Crank end play, destroyed converter, 408 nightmare

I've always wondered how that is even possible? Not having seated all the way back? But I've also seen ground up pumps because of this. Mostly due to those who bolted converter first. It's not like the flex plate adjusts? Just never have been able to visualize.

It happens. The input of the converter doesn't get all the way into the pump. And you are right, it can kill the thrust and wipe out the pump in the trans too. The thrust by far more sensitive to load against it on startup especially.

You can tell if the converter isn't all the way into the pump. You should be pulling the converter up to the flex plate by a long way. If you barely have to move the converter just a little bit, it's not in the pump and will kill the thrust and if you have my luck, kills the pump in the trans too.
