Putting the motor in isn't to difficult. Its wiring and fuel supply that are the main issues. It would probably be easier to install a fuel injected magnum V8 from another dodge.

It should the 3.9L V6 is based on the V8's. I am pretty sure that they have the same bellhousing.

Need harness, and computer from donor truck. Reason being, you are going to have a couple extra fuel injectors on there, that you need the wiring harness to hook up to, and the computer needs to be aware that they are there.

I don't think you need to change the fuel pump.

A 94 PCM isn't going to work in a 98. You'll need the PCM for a 98 and wire harness(as mentioned) for 98 though. Which btw only uses one temp. sensor (the one under the alternator. So you want a new temp sensor for a 98 also.
