I've been told that they put an adapter to go from the SAE to the ford
pattern to use the ford transmission on the *older* trucks (6.9-7.3) and
that at the powerstroke phase they simply use a ford pattern.  Second hand

Is it possible that they just were giving you bad motors?   Or that the 446
might be a better motor than the 404?
