I'm looking to get more power out of my truck that currently has the 5.9 has anyone put a 6.4 into it? Is it an direct fit for the most part. Possibly any ideas that would work?

 

Sounds like it would be a super fun project.
I've never done it, and don't know if anyone has. What transmission would you plan on using behind the 6.4? Also what would you plan on using for operating the engine? Factory MOPAR ecu or stand alone?

 

No. Not a direct swap. Not even close. Mounts are different, electronics are different, and many other things as well.

 

I am doing it just to get the motor in (not running) you are looking at about 5-6K if you get the motor and trans for 2K
