A performance package would be a AWD 3.5 Ecoboost..Could it be done?.Sure can. The Ford Taurus SHO has been running this for quiet some time now. More power less weight. GT 350 anyone..
Ahhh. My choice would be like the truck line up. Base v6 or I4 ecoboost/5.0.
V6 Ecoboost and a short deck aluminum 6.2 based for a Mach1? Shelby? Something, to compete with the general.
