I'd be willing to bet that the ATX cars are far below MTX's in failure rates.
agree but this is simply because ATX cars spend much less time at high RPM. Higher RPM = much worse crank whip. Non SVTs with MTX also probably less than SVT because peak power at lower RPM + slower reving = less time in the fun zone. Personally, Im not sure if DMD is needed with ATX (unless it has 200 HP and level 10 treatment...Ford has not installed DMD except on new MTX cars (I think).
