A quarter of an inch???!!! WOW! I'd say the crank is ruined. The thrust part of the bearing isn't even close to being that thick.

do you guys think it was the original convertor that ballooned it had the d-6 in it when i bought it cant see that ballooning it only stalled at 1300 and is that the knocking noise i heard

That knocking noise could be a number of things since the thrust is gone. A quarter inch makes things move around a lot internally in any engine.

A way to tell if the torque converter is knocking is to disconnect it from the crank. Then start the engine and listen.
