Why change the 904? Easy rebuild and you're good to go without having to dick around with changing the yoke and cutting down the driveshaft for the 727.
I had 4:10's in my 727 equipped 440 Dart. Absolutely useless!! Put in a set of 3:23's last year. Best move I ever made, next to ditching my ex girlfriend!!
For my 1972 440 Dart with a reverse manual valve body 727, what floor shifter do you guys like. There are far too many to choose from. The B&M Quicksilver, Hurst Pro-Matic, the Turbo Action Cheetah SCS........etc. Any help?
