albeeno open up your eyes. Car companys have been doing this for a long time. they underate their cars performance times, trust me i did my research. Also why are you suprised your car is so close to the srt8s performance times? first of all the 4.9 sec is underated but lets go by what you believe , the gt is 0-60 5.1. so your saying .2 of a second off 0-60 is nothing? that is alot in my book. people modify their cars to hell to shave off .1 off their 0-60. this car will eat the gt in top end and 0-60. i guess you should stick with your stang because if .2 off 0-60 is nothing for you then a .4 sec difference between the gt and the gt 500 should be nothing to you either. enthusiast and car mod nuts by srt8s and z06 and gt500 because they want the more performance oriented model of their company of choice. looks like you want viper numbers out of .4 liters added to an 5.7 liter engine, sorry you need to come down to earth.
ps: I still love ya,
