from 1967-1974, which camaro year model is the fastest? and which package and whatnot.?

Have just been curious on which one is fastest cause i love all of those year models of camaros and hope to get one somedaythanks

1969 ZL1All Aluminum 427Only 69 made (If you get to see one, take a picture, you might never see one again) 1969 Z/28 was good for road racing Any 69 with the 396 was a good drag strip carInto the mid 70's the performance dropped off drastically, mainly because of fuel cost / EPA, etc.
