I'll let you know, i haven't broke any of them, or had any issues with either of them and i have broken many many 727s from every builder in my area and quite a few beyond, but MS is the TC man and the go to diesel trans man.
I have the 1st externally adjustable A&A/Dynamic trans, so for those that know that is a old 1st Rick did with the 727 and that trans is just fine to this day behind 780/1400 hp
The next A&A/MS is behind 700/1200hp
MS 46e is behind 600/900hp MS 47e is behind 1100 ft cummins
Eventually i'd like to get the new cummins to increased levels.
