Is there such a thing as a 5000 stall converter that is streetable ?

FWIW, I had my extra converters matched after i found performance that I liked. The original converter "rating" was "4400", but they actually flash to 4,900 - 5,400 in my 360 Dart Sport combo, mostly depending on heat and humidity. On the line my footbrake held to around 3,000, but that depends on different factors too. I've always wondered how converter companies rate them and if they do it the same way. One different brand converter had a similar rating but it never felt as "crisp" until I had it rebuilt & "matched". There's more science & engineering in converters than many people realize or know about, including me. I never drove it on the street but pit and return road response seemed good.
