That is one of the craziest statements I have ever read here. It’s gotta be satire! Otherwise, how do you figure that! The 727 came out a good bit before the 904 and has won awards on a few fronts.
The factory flexplate is fine for most cases of upgraded engines and such. The SFI parts, while much stronger & capable, are really not required on most street driven vehicles. If you don’t have one or it makes you feel safer to use one, then use it. There is no real downside. Except cost.
I normally pick up a B&M flexplate if I don’t have a factory unit.
