My Sheriff cruiser is the 2008 Taurus with the 3.5 ltr V6, 265hp, 6 speed automatic. It flys. Coming up to 25,000 miles of lots of city stop and go driving and a few miles of top end "cruising". Hasn't had any problems with oil changes and tire rotations every 5K.
I can't imagine what another 100hp would do to it. Torque steer is evident with mine when you punch it. The old SHO was only available with an automatic if I remember correctly.
