The 2013 SRT Viper
has yet to even hit dealerships, but that isn't stopping John Hennessey
and his team over at Hennessey Performance from already working out a pair of new Venom packages for the latest Chrysler
supercar. The 2013 Viper made its official debut back in April at the New York Auto Show. Packing a monstrous 8.4-liter V10 rated at 640 horsepower and 600 pound-feet of torque, it wouldn't seem that the all-American supercar needs any more power, but that never stopped Hennessey in the past, and it isn't about to this time, either.
