Derek Ekin’s 2006 Chrysler 300 has had its 3.5L V6 replaced with a 3rd generation 8.3L Viper V10. Derek did all the work himself except for the wiring and ECU work. The swap took him a year because he had to learn for himself each step. The Viper uses a T-56 six-speed transmission. The suspension has been upgraded with Eibach adjustable coilovers. The gas tank was also upgraded to a custom Aeromotive tank.
