yes and no - Case in point - ME! I have a 400 hp 360 3.23 gears and a 3800 stall dynamic 9.5" converter I used to have a mopar 175k converter with the same setup and burned it up with the tranny - Why? It was slipping. The 9.5" dynamic converter lowered my cruising RPM , raised my mileage and lowered my ET at the track. It was more efficient and designed to handle the slip different then the old school mopar unit The pitch of the fins, the stator angle and the case size determines flash stall. I wrote a 2 part article on it a few years ago and went to dynamic converters and watched them assemble one and saw all the differences they had to choose from - neat shit right there! Anyway - the car cruises 3200 @ 75 - so anything under that should be slipping and heating up but the pitch of the blades combined with the smaller case ( 9.5" diameter compared to the 11" stocker ) made the converter slip only when it was overpowered with torque ( when you nail it ) otherwise it acts like a stocker.
