It was a relatively economical swap, which was good because I didn't want to spend too much on a 4 door c body:) Besides the wiring, fuel pump and filter, there were only a few things that add up. I think I had about $100 in plumbing the fuel sytem, and another 100 in a pass thru speed sensor so I could keep my speedometer and cruise, but still send a signal to the pcm. I ended up putting a mopar performace pcm in it, but it was a $50 craigslist find. I had to buy a car 360 pan and pickup because the 5.2 magnum has the same pan rails as a 360, not a 318. All of my mounts worked from the 318, and I actually used the y pipe off of the Dakota donor truck because I am cheap:) I need to eventually have an exhaust bent because it hangs low. I purchased the dakota donor with a blown trans for $300 and got my money back when I scrapped the bare shell, so I only have $400-500 invested in the swap. Probably the best bang for the buck mod I have ever done!
