I have a 2005 Dodge magnum RT rear wheel drive and was told a few months back that I had a crack in my engine block after taking it to dodge and getting a chemical test. Since I've been looking for a motor to drop into it instead of spending 4k on a rebuild. I found a 2013 hemi RT motor with the transmission out of a charger and called around asking if I could drop the newer year motor. So far I've been told no. One of my buddies told me that all I have to do is take the mounts off of my motor and put them on the new one. He also said I would have to switch the harness. Is this possible?
