If you aren't aware, there are just a few things to be aware of when installing a 5.9 magnum... it really helps if you get the flexplate with it. You can buy one, but saves money. Then you can run the neutral balanced converter. Also, you'll need a car 360 oil pan and pickup. You can run either LA front or Magnum front. If going LA, you can get a damper for the 5.9 magnum. If you are going to run a mechanical fuel pump, you can get the kit from Hughes for about 30 bucks to work on the magnum cam. If you change the cam, you can get a long snout cam so running a mechanical fuel pump is no issue. It's really not much to all of it, pretty simple swap.
