727 Torqueflite SFI Case
I have been running 904s for over 40 years and only broke one ( my fault due to shifter out of adjustment ) The one in my Dart now has been in there since 2017 , I don't make big power either in mid 500 h.p range. I have a really good trans builder , he rollererizes them and as well as a few other tricks . He built me a complete ready to go spare a few years ago ... I haven't needed it ! I have a CSR shield I installed years ago and having it adds another hour to a trans or motor swap . It is out of certification but Its not required for my class and e.t. but I leave it in for safety.
