The 3.8L isn't OHC, it's your standard 12 valve pushrod engine, although it does incorporate a balance shaft over the camshaft.
I'm sure the cam profiles could be adapted to get the low end torque out of the 3.0L Duratech that my heavy Windstar (near 5000 lbs!) needs to get moving. If they can make a 2.5L SVT run 200 hp/170 ft lbs, I see no reason why a 3.0L can't hit 200 hp/212 ft lbs. Hell, they could probably make 220 hp/245 ft lbs easy, with a rather flat torque curve. The engine would be a hell of a lot smoother too.
