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

The answer is YES. But, if the operator isn’t competent then NO.

Thats why God made throttle pedals and shifters. Learn to use them correctly and you can run about any converter you want.

Physics has little to do with it.

yea, I don’t get why anybody would argue about the validity or issue running a high flash vert on the street.
hundreds of guys on drag week and other such tests do it every year.
