UNLESS your daily driving it / commuting with it ...... who really cares?? Get the best converter that works at the track , get a decent cooler on it and a trans temp gauge. Street cruise it.... thats what i would do .....  Agree 100%… converter technology has come a long ways. I have never run anything but 8 inch converter suited to best Et at the track, and everything I have had in the last 30 years has been street/ strip. Good cooler, have fun.  Run what the combo needs to go fast. With a decent trans cooler it'll be fine on the street. I've run a couple of different 5000-5200 converters on the street w/ no issues.
