Hopefully they aren't just patronizing the Pontiac guys.

I'm guessing they orignally added to much clearance by design, much like the piston manufacturers set the piston lower in the bore, and most machine shops err on the loose side for most machining operations.

Problem now will be if they make the tolerance too tight, they will get noise complaints, and most definately will cause problems when someone uses a plate that's been "adjusted" already, and the owner knows nothing about all this, and doesn't know to check it.

Some of the problem was with teh returned hulls they got back had varying immpeller blades and some I know where shaved. that shoudl all be fixed and there was talk about them including a plate to go with the pump.
