I've said it before and I will say it again... slapping a supercharger on an engine not designed for it can only cause problems later on down the road. Even the cast pistons in the LSA are a liability.
Unless the Z28 package w/ the S/C includes a set of forged pistons, the reliability that I want from a FULL production Z/28 will keep from buying this package. Or a full warranty to 100K when buying this package...
For the price of a GMPP package, I could rebuild the LS3 for forced induction and still have money left in the bank. I have NEVER liked the reliability aspect of slapping a S/C onto a motor designed for N/A. I understand that it has been done in the past, but that does not make it the right decision.
