Where to buy a 727 transmission

#1 Stop buying crap off the shelf converters..

#2 Get a quality 9.5" unit from PTC, Dynamic, Turbo action etc. Made to YOUR specs. $475-625.

I don't understand why people spend thousands on engines then refuse get THE most important piece of the drive train quality measured.. It's a HUGE deal to get the most from your combination..

You shoot yourself in the foot every time you don't.
