I’m thinking of swapping the 4.7 out of my 2002 ram 1500 for a 360 does anybody know if I will have to move the motor mounts?

 

Wiring harness, computers, and transmission controls are completely different. (unless you have a manual) The older PCM won't run the newer trans. It would be easier to drop in a 5.7, just get the PCM, and harness for it.

 

The motor and tranny is out of a 2nd gen and I’m getting a new harness do you think it would work then?

 

Not easily. And maybe not at all, depending on the year of the donor. Lots of things changed in the electronics, and how gauges and such work over the years. You will likely have to re-pin the connectors for the body side of the harness........ That will be an exercise.

Still and all, replacing with another 4.7 would be easiest, and even if you have to pay more for the motor, it will likely still end up being cheaper. Going to a 5.7 wouldn't be too much more difficult, as all factory parts are available for that swap. Going to the 360/46R? trans, on the other hand, is going to be a major undertaking, and will most likely require some fabrication work as well. (the trans mount isn't going to be in the same place......)

Unless you are getting the 360 and such for free, it just isn't worth it. (and even then, I wouldn't wanna do it........)
