Hi all I'm in need of a new motor for my 2014 ram 1500 4x4 I found a motor for sale its a 5.7 hemi out of a 2012 chrysler 300. Motor has been completely redone bearings, lifters, cam valve springs etc. My question is what's the difference in engine and what do I have to modify to make it work in my ram 1500? If any knows thanks in advance.

 

Same basic engine except the truck cam is different and you will be down on power (about 20 hp). Otherwise swap your oil pan, front timing cover for the accessory drive and your intake manifold.

 

As well as ALL the sensors.

 

Likely, though 12-14 is within the same CAN generation and may actually be using the same ones.
