2016 Sema Mopar Hemi Swap
Understood entirely, And not knocking it at all. Just pointing out possible hurdles for you, that may end up costing you more $ than the "crate" kits..or even worst...acquiring a pile of parts that requires a bunch of hard parts, or special accommodations to work at all.
Like i said before...(and this is not meant to be directed at you, nor is it an insult) I talk to someone every single day that wants a plug and play, no laptop required, magical ecm/harness kit that will control their hemi, AND their 46rh-w/e, or NAG trans they pulled out of a camper van for $50, AND they want said harness to be $900. And every day i have to burst bubbles that there is no magical ecm/harness kit that grows on tree's. And the "truck" engine" and "camper transmission" they "scored" for $1000 combined is about $5000 away from ever running in a vehicle.
Now, you're being smart and asking questions before hand. So you're chances of getting stuck with a truck engine and a camper trans, and no feasible options, are slim :)
