Torqueflight 8?

The explosion "problem" stems from a failed Sprag that can happen to either a 904 or a 727. It typically fails from over revving the trans during a water burn out at a drag strip. Are you trying to say that a 727 is not stronger than a 904? I did not argue that a 904 would not work behind a 318. A 727 will live longer behind a 318. I have a 727 behind everything unless it is an A833. There is always a choice and multiple reasons why there is not just one motor or transmission, especially on the street, which negates your "exploding" reason for picking a 904.
