OEM warranties are derived from validation. There isn't an aftermarket company that exists that tests to the standards of an OEM. Aftermarket companies set warranty based on their experience with a product and their level of confidence in a product. Companies like LPE have sufficient financial strength to back their warranty. On the OEM side, GM would have to fully validate a modified LS7 and there is no way it would be remotely close to cost effective.
If you think that the 5th Gen IRS puts power down more effectively through the corners than a C7 Corvette, you may also think a more powerful Z/28 could do something amazing at the Ring. TEAM Camaro and Chevy Performance could choose to take a modified LS7 in a Z/28 to the Ring with an off road / racing use only disclaimer IF they thought it would sell Chevy Performance heads, cam and ECM with 600 RWHP. No warranty. No EPA. Just bragging rights for the fastest car GM ever sent to the Ring. Not that any Chief Engineer at a Big Three company would ever think that way or that anyone from TEAM Camaro ever drops in to Camaro5.
Lowdown, have you started that thread yet
