hey, I got no help to offer, but I'll be eavsdropping. Want to do the same to my '96, but might settle for 5.2L. I like the 3.9 just not a V8, just my opinion... seems almost like waisting money building a 6.

I did it to my 99 dakota, items i know you need are a pcm for a 5.9 for YOUR year truck, wiring harness, i have one for a 97 model, which for me the only one that would work was a 99 model, also a fan shroud for a v8, everything should work including the trans,although it might not last long??? mine lasted for around 9 months but my motor was far from stock!! Hope this helps its a easy swap if your mechanically inclined!! Don't forget about the extra o2 sensor you will need to put in, in the left bank.

I want to do a similar swap... 3.9L to 5.2L/318. Is it the same amount of work or less? Also, I have been told that only a 1997 tranny will fit my 1997 Dodge Dakota 2wd. Any help is useful... aslo, what engine is the best to go with for the optimum gas mileage, horsepower etc. etc.... I want the best bang for my buck.

RE: swapping 3.9 to 5.9 in responce to your question i would put a 5.2 in better gas mileage and just as good power as a 5.9! a 360 will get you maybe13-15mpg but a 318 will get 18+

When I did my swap I put a 5.9 360 out of a 97 ram and dropped it into 99 dakota and kept reverything from my v6, trans, motor mounts, and all acc.. the only thing i need was a pcm for my year truck, wiring harness, and fan shroud, also had to weld in a new bung for o2 sensor thats it pretty simple!!
