Thanks 72 for the reply.
I have read about the 727 mating up and I have access to one if the 300c is out of the question, but if the 300c has a superior trans I wouldn't be against doing a bit of surgery as the car isn't original by any means. Is the rear end useable or even decent in the 300? Or is it better to just use the older style 8 3/4 or something of that nature?
I have also read about the computer, I believe the Mopar Performance one is a AEM unit with a Mopar sticker. That's what I would be looking at, I have seen AEM in action on Turbo Honda's, MR2's and such and they are very nice, can do almost anything you want with them. I also have a Wideband 02 sensor to tweak the tune if need be.
Has anyone tried any other parts from the 300? Brakes? Suspension? Or does nothing even come close to fitting?
