Well I hope they have gotten lots better over the years. The American Powertrain OD units I’ve use back in the mid to late 90s couldn’t handle 400 hp/tq in a 68 440 auto Charger. After the second 1 killed the tranny we sent it to the place that sold us the OD units. 3rd time wasn’t the charm. It went back to the regular 727. Kim
