Yes.
mmmkay, so stroke it out a bit, say to 3.3 or 3.4L (don't know enough about the 3.0L Duratech to know if they could do that or not...), and there is your added torque. Give it a convertor with a bit higher stall speed, and viola!
I must say, the Windstar does have gobs of torque down low. It will spin the tires (stock Generals, 215/70/15's) at only 3/4 throttle on dry pavement from a standing start. Hell, my Contour can't even do that at full throttle. I suppose it could if I had a stick, but the slushbox in the 'Tour will in no way spin those tires off the line unless you brake torque the hell out of it I suppose. Wishing the 'Tour had the 'Star's torque....
