Not possible. All wiring for entire truck including dash and all the way too tails has to be swapped from the 1500 and would not work in a dak. You can figure a way but good luck maybe best 5.7 hemi to target would be the 2003 only.

DON'T YELL AT US!!!
It is possible and has been done. It is NOT easy and just grabbing things from the Ram to shove in the Dakota and **** it all works. That engine wasn't even made to sit where you're wanting to stick it. You literally have to marry two different sets of electronics together and hope it works because if they don't it won't even run. If you don't have the technical expertise to fab things and screw with electronics or the bottomless wallet to pay someone else to figure it out for you...then this is not something you want to tackle.
