DieWilde go to this website as they sell the engine mounts and torque rods to put a BB in your Dart. http://www.engine-swaps.com/. They also have the headers. I'm not sure about your power steering if your car was a Duster or Demon I could say but the people at Schmacher can say for sure. Personally, I used a built 727 and 8 3/4" but you'll also need a 3 core rad with shroud and maybe larger torsion bars.
