The st200 along with most of the v6 from ford of the same duratec family , had a second set of butterflies, low down in the intake manifold. These in effect blocked off one of the intake valve to increase low rpm air speed., They then open up at higher rpm which gives that surge feeling you describe.
The later 3.0 engines and the Jag derivatives didn't have these secondary butterflies.
