need advice: 440 in a Duster

Start off by talking to these guys http://www.engine-swaps.com/. They make the mounts and headers to do the job. Starting from the front you'll need a minimum 3 core rad and try to get one with a fan shroud, may need thicker torsion bars depending on what you've got now, no power brakes but power steering with Schmacher header, disc brakes up front and at least 10" drums out back, new drive shaft, at least a 8 3/4 rear, sub frame connectors, 2 1/2" to 3" exhaust. I'm sure I forgot something but this will get you started.
