Can my 08 Charger 3.5 be replaced with a 2005 5.7 hemi
If so what needs to be done.
I was told it would bolt up to the trans. What about mounts? exhaust? suspension? comp?

 

I would imagine stiffer springs? And if your swapping for a Hemi, I would go with a true dual exhaust system. And you will need a new computer I am pretty sure,I'm no mechaninc, but that is a pretty sure thing when switching engines.
