Oh wow... the Z06 has an inferior engine?!? Are you serious? I didn't know that! (pardon the sarcasm) That seems to be the only major plus in this car (plastic sidepaneling on the interior and the worst leather seats known to man among other things) The LS6 is a fairly widely used tuner engine especially for american exotics and kit cars (don't laugh). Among these would be Callaway's C12, and Mosler's MT 900 Photon. I'm a viper fan true to heart, but the engine of a z06 is impressive out of the box, and it's very versatile. Don't knock it boys and girls until you know what all it can do. (Just remember Einstein failed science) Just because it may not be amazing to start with doesn't mean it doesn't have the most potential out of any v8 (contest that!)
