The Charger will get an upgrade to a 440 & a 4 speed from a 318 , 3 speed on column and It's color will be Plum Crazy with white interior. The GTX, will also have a color change to Sublime with a 440 & 727. The reason I am changing the color on the GTX is that I do not have the original motor and I already have a Big Orange car with a Flag on top.
