What you are planning will not be an easy task, you will have to fabricate mounts, find an adapter kit for the Ford trans to dodge engine, redo exhaust systems, make up wiring harnesses for the computers, sensors, install a totally new computer control for the Ford transmission, fuel delivery system will also have to be modded for the Hemi engine. I'm sure I missed a bunch of stuff that will also have to be done and if your state requires inspection before it can be licensed it won't pass.

Nope I live in Arkansas I have everything that needs to go with either truck but I didn't know what all I needed to change for conversions
