Bluebuckmobile 1.1

I added configs for all three of the skins, added a 440 cui engine (with a louder variant), 3 speed TorqueFlite transmission, 3.21:1 rear differential, and hollowed out exhaust pipes for the louder engine. The new engine I added has a rating of 280 hp since during the early to mid 70s Chrysler had to de-tune their engines in order to follow the gas and emission regulations.
