February 25, 2010I would like to know how hard it is to swap a 318 V-8 from a 95 Dakota into my 93 Dakota that has a 3.9 V-6 ? I bought a 95 Dakota 2wd (body is very rough) with a great 318, I want to swap the 318 into my 93 Dakota 4x4, It should be a fairly simple swap? Any information would be a great help.....
February 25, 2010I did the same swap! I had a 93 4x4 with a 3.9 v6, and put a 5.2 v8 in it! It was a bug change! When you pull the motor, leave the engine wireing harness on the motor!!! It will bolt right up to your v-6 tranny. They should both have the same tranny. The y pipe will also line up to the manifolds of the v-8 or you can get shorty headers like i did and they will match the y-pipe also! Once motor is in, drop the engine harness in the stock place across the firewall and use the ECM for the
v-8 in place of the v-6 ECM and you will be ready to run. It is like a plug and play installation1 I done mine in a week by myself just in the evenings after work, and part of weekend. Could of done it quicker if I would of stayed on it....

February 26, 2010Hey thanks so much for the great info, I feel better about the project already!
April 6, 2010Sweet, that truck is awesome. I`m looking to do the same. I have a 92 sport ext cab 4x4 v-6 w/5 speed tranny. I want to put a 5.2, will I be able to use the stock 5 speed with the 318 or do I have to change to an automatic? thx.
Also, I don`t understand what your saying about the wiring harness to leave it on the motor...do you unplug it at the firewall and pull it all out with the v-6 but I guess ya need to have the harness with the donor?
April 6, 2010thats a sweet little truck!!!!!!!!!!!!!!!!!
July 24, 2010does the donor v8 need to be of the same year as the truck youwant to put it in ? I have an o3
July 25, 2010If you are doing a swap to a v8, try to get the donor motor with the engine harness left on the engine. all you have to do is disconnect it from the ecm and toss the plug up on top out of the way. Make sure you get the ecm for that engine. It will be cheaper to get it all at the same time and less headaches trying to run the wires again. This way you can bolt it in place, hook up the fuel lines, exhaust, hoses, and put the ecm on the passenger fender where the old one was and plug it in. It is as easy as that! Now I did have an issue with the pan hitting my bottom radiator hose connection, but that was because I had a body lift on it. Was an easy fix though. I just bought an electric fan setup and removed it!! Wish i still had the truck. It was fun...
July 25, 2010That works great when swapping to a similar year engine... but when swapping to something a little older or newer the harness may be different, in which case you need to use your factory harness and any sensors that are different as well. But you will need the PCM from the year of your truck and for the engine and driveline that your swapping in
July 25, 2010thanks for the quick replys. and the info .
now all I have to do is make some phone calls to the local junk yards and see what I can find.
