Since we're on the engine casting side now--I know of no Porsche engine 
casting connection, but I believe GM did license the Renault vacuum casting system 
used at Tonawanda.  It allowed the use of reusable molds for the aluminum 
parts (I'm sure the cast iron parts used reusable molds as well--this was a Chevy 
and not a Porsche).
