How many using an A500 overdrive ?

I just spoke to precision torque converters https://gopnh.com/ They will build a lockup converter for an A-500 or A-518 to just about any spec you want. They said the can give up to in the area of 5500rpm stall and with a triple disc converter clutch and a billet cover.
this is interesting that they say they can build them with triple discs. I inquired with John Cope about WOT lockup function when I purchased my valve body from him and he stated that the single disk converter would slip (obviously) but he didn't state that triple disc options were available (maybe his converter supplier doesnt offer triple disc converters) if precision can indeed offer triple discs and fit in a stock bellhousing with say a 9.5" that would be HUGE. I've even contemplated adding a spacer between block and trans then running a billet cover to allow the extra clutches, kinda like the 2 and 3spd lockup 400s that are out there now for all the fast blower and turbo combos.
