I saw on motortrend, or some car news show this weekend...the GT40 has started production. 5.4l Supercharged V8 making 500+ hp and 500ft lbs. of torque.
I believe the Viper GTS is 455HP. There's supposed to be a new, bigger v-10 coming around. Something like 9 liters?? The viper is a smaller car than the GT 40 though..atleast it looks that way. Only one way to find out!!
As for the SRT 10 - sure it might be fast but that thing is too dayum big!
