Just check with your dealer they have an installation guide for
retrofitting Hemi into older cars. BUT it's not going to be cheap.You will
have to deal with enging computers BCM & trans computers TCM. You will need
a wiring genuis to redo the complete wiring. If you can get a copy of
Mopar Action they did a swap into
a GTX although they used a 5 speed at Street & Performance in Mena Ark.
They make custom wiring harnesses for the new Hemi's too...
