I never had a trans explode either, but when I built the new 500" Stroker I decided to make upgrades to the transmission.
It gets expensive pretty fast. Got the A&A Super Sprag, Billet steel front drum, and after noticing splines in the front planetary were cracked and a few fell out, got the steel front planetary gear too. Then the pump with modified stator support. That is in addition to replacing all the servos with dual ring billet versions, the Cope manual reverse valve body, and a bunch of other stuff like light weight sun shell and aluminum rear drum. Pretty easy to have $4K or more into a built 727.
