I have a 2007 Grand Marquis and I am wondering if one I can use mustang parts on the 4.6 liter engine and secondly how hard is it to turn my beast into a Marauder(as far as I can see other than finding the parts themselves the interior looks to be the hardest). I actually bought the car in a pinch from an older gentleman with every intention of trading it in for another mustang to replace the one that I used to have. But after driving it for awhile I kind of feel in love with it and I won"t go back to a little car. Now I just have to make her a badass LOL.
