retro fitting Magnum F.I.

If you are staying close to stock specs i would say it would be a good way to go especially if you can get an installation harness from someone like Painless. The engine in the picture appears to be to radical to work with the stock PCM. For a F.I. engine like that you would need an after market PCM from the likes of FAST, Accel or Holley and there wouldn't be much from the stock magnum system that would be very useful.
