Well so much for my idea LOL. I know that the 3.4 and 3.6 share the same bore, the 3.6 achieving it's greater displacement via a longer stroke, but some evidence would seem to indicate that even if Porsche didn't change the case halves at all, that their process or control over the process improved, as there seem to be plenty of D-chunked 3.4s, and not so many 3.6s.
