•*The Z28 has not always been the highest tier when compared to the ZL1 and the fourth generation SS. This directly contradicts the idea that Z28 is superior to SS or ZL1.
the rpo codes that are listed have not been kept that way. for instance in 76, the RS RPO code was Z85 and there was no SS or Z28. for 1970, the RS was Z22. in 68 there were 4 different Z28 levels to choose from, 73 had no SS, 75 lost the Z28. and after looking at things, the Z28 RPO code, which was originally designated for the "Special Perf Components Pkg " is now the 1LE RPO code
so maybe in addition to the RS, SS, Z28, ZL1, we need a strictly 1LE camaro
