The PS makes it much easier to drive. I learned a lot from the Duster build although I don't fully understand everything I learned. The Duster was easy to drive with a factory 24:1 box. Might have been the weight of the car but it drove nice. My Coronet on the other hand was always a pain to drive with a manual box so now I'm enjoying the PS.

I'm not enjoying the 5 speed in the Coronet. I used to like driving it but now after spending a year with the full manual 727 in the Duster I'm not a fan of using a clutch pedal. I really liked how the Duster drove with the 10 inch converter and the full manual shifting. I don't think I can bring myself to put an automatic in the Coronet since it is a factory 426 4 speed car so I might end up selling it. Pass it on to someone who doesn't mind shifting gears. I've owned the car for 40 years so it might be a tough decision to make. I'll spend some more time driving it this summer and see what I decide.
