Just saw this thread for the first time. It is very informative. Thanks for all the information Matt.
But on another note, I find it sad that other GMMG cars are getting the C5R 427 (are they the exact ZL1 setup?). The Zl1's should be the only ones that received these packages. Correct me if I'm wrong, but one difference between the 69 ZL1's and other COPO cars was an aluminum block versus cast iron. So there is even a difference in the motors. Now the only difference will be a badge.
The ZL1 was supposed to be the bad boy of the Camaro
, with others having the C5R 427 seems like others are getting the benefits of the ZL1 without paying the price of the ZL1.
At least put a different 427 in the other GMMG cars.
Sorry, if my argument went off track, it is upsetting to me. So does that mean other GMMG cars can get a LS6 Phase 2 475 hp package instead of the LS1 Phase 2 435 package installed, etc... When do you say when?
