The questions that arise from your questions are: Who's doing the install? How much are you willing to spend?
My first recommendation is to get a used 3.0 from a 2001 Taurus, add the DMD, a light porting of heads, add the SVT cams. With all that you should be at or around the price of a new engine and have a little left over to offset the install.
If you want new then get one of the LS engines that Terry is selling with the DMD and an electric water pump.
Both would offer the enhanced power your looking for and handle a Turbo later with some extra work(Forged Rods, Trimetal Bearings, Port matched exhaust and intake).
I'm not the most knowledgeable about all this so if I'm wrong. Let me know.
