Mopar 904 trans pressure

To figure that out , you would need to know the dimensions when the converter was brand new . I have talked to more than one converter company that says that their converters are built with tighter endplays new , and it will change to their desired endplay after a couple three runs . That would indicate some permanent ballooning , but good point that it could balloon more , during operation , then return back .

Then why anti-ballooning plates?

The original application for an 8" converter was an Opel way back in the 1960's . It wasn't designed for the kind of HP that is being put to it in most of the racing applications currently . The anti ballooning plates are meant to beef up the shell , it works in conjunction with furnace brazing the pump fins inside the shell . Most modern OEM converters are furnace brazed from the start . The older converters , just had the fins staked in .
