I know we have to talk non Lock up for a minute but how does the Tork master compare to a factory hi stall? All else being equal except let's say for a minute I found a non Lock up 727 to fit my engine. Is a hi stall for non lockup (factory converter) the same stall as a factory hi stall for a lockup trans?
I'll answer this ... no , I'm 99% sure the spline count is different so you can't put in the wrong convertor.
I drove one of those early lockup convertor cars and my god do it suck.
You should be able to switch your lockup trans over to a non lockup by changing the front pump, assembly and input shaft assembly along with the non lockup valvebody .. The transmission case is the same between the 2.
