For 8K I could build a 5.0 based fox body that walks all over any of these in the 1/4, that isn't the point.k the z06 is 75k.. the gt500 is 45k.. the vette is 48k.. so for 30k that gt500 would walk all over the z06.. hell probably with half that.. for 3k it would probably stomp the vette.. idk the specs all that well on the new vettes.. the z06 didn't even STOMP the gt500 when it came out.. it beat it and the viper but not by a huge margin..
Point is dollar for dollar GM still makes the best performance vehicles stock.
