Motor swap help

[Georgia boy]

I have a 2002 Dodge ram 1500 with a blown 4.7 and I have a 6.2 with trans, computer and wire harness. Would I need to change out my motor mounts? What else would I need to swap out to make the 6.2 set up work?

Uh boy lol....honestly most of the truck. How much harness do you have?

Edit: let's go a few steps further. The engine itself will be a physical bolt in. Trans you may need to fab a bit on the mount/crossmember (8HP90 was never available in a 3rd gen Ram). This is where the easy part ends. 2002 Ram is first year for that style PCI bus system in the trucks. Your hellcat combo is out of a 2nd or 3rd gen CAN bus vehicle. Existing PCM/harness obviously won't do the trick, hell even a 1st gen CAN bus won't do it (6.2 is a VVT engine). You would have to figure out how to interface the control section (PCM for engine, internal TCM in trans) with the rest of the vehicle. After that would be support systems. That 9.25 rear probably won't last long, requiring an upgrade (easiest being D60 from a Viper truck). Gonna twist up some leaf springs with 650ft/lbs lol. Exhaust: D port headers were never an availability for the 3rd gen, best fit possibility MIGHT (and that's a slim might) be Grand Cherokee SRT manifolds, otherwise you're dealing with port mismatch (or getting a custom set of headers built). Cooling will require a custom radiator to cool that thing as well as completely reconfiguring how everything routes to the accessory drive (alt, A/C, PS, etc). Did you get the intercooler tank and piping as well? The whole thing snowballs quickly. Obviously you have disposable income if you got your hands on an entire 6.2 setup, but unless you're able to do this whole mess yourself, the labor bill will rack up very quickly.

Not to be discouraging, but the engine mounts are the least of your worries. The electronics is the problem as mentioned. If you are serious I would recommend having a notebook and list what you have and then do the reseach on how to make it all work. Using stand alone systems most likely would be the most expensive and simplest.

I have a complete donor vehicle.

Throughly document and tag your harness. Research how to integrate it into your truck. Maybe talk to Hotwire to see if they have a ready solution. Good luck... it'll be a great swap when completed..
