A 4K stall CAN be fine on the street, if it is a modern converter made for the street. It has to be built so that it achieves enough lockup to keep heat down and not ruin mileage all to hell, plus flash on demand when you stab it. Old, obsolete converters cannot do that. That's why you need to spend good money with a reputable company for a converter, not some POS B&M Holeshot.
