My 727 is also very stock. I run a Turbo Action reverse manual valve body and a Dynamic 9.5 converter. I also installed a bolt in sprag (rear overrunning clutch) and eliminated the gov and blocked the accumulator. I use stock Mopar clutches and steels since I have a small supply of them I saved up over 24 years at the Dodge dealer doing auto trans repairs. I even use the stock Mopar seal kit which I also had. I dont race alot as I usually go to the track once or twice a year but I do alot of street driving. Mine has been in my 63 since 2006 and has never had a problem and is still working fine. Ron
