Mopar A Body Overdrive Conversion
A 200R4 can take a LOT of hp when built right. You can install a 200R4 with no floor cutting but do have to make a small cut to get it to fit. Just look up the thread by Mopar To Ya. He installed on in his Dart Sport. Also with the 200R4 its all HYD which is big plus over the 700R4.
