(In the case of the pontiac that would be the stamped metal plate) Ford impellers have very close tolerances between the stamped vanes and the cast contoured wall. Kind of like the factory stamped metal plate. The stamped impellers better follow the contour of the steel plate with-in .030"-.040" otherwise too much leakage past the vanes.

So, If I have a stamped impeller and it is not contoured, it would be crap, and another stamped impeller contoured, it would be good to go? I just want to make sure we are on the same page, too much Knob Creek tonight.
