not sure how anyone can compare to diff transmissions like that to performance. Its hard to say, which converter is a better match? How can none have two identical converters for two diff transmissions? The PG 1.76 is plenty strong... been 1.0x short times with a stick 1.76 gear set and 2000+ lbs car... Also ran 850HP Mopars behind 90% stock 727 too in heavy cars... 3700+ lbs.... Its not cheap to switch either. Unless your starting from scratch
