Good evening, looking at picking up a 2006 5.7 hemi from a dodge charger and looking to see how hard this would be . I understand I need to change the K member to a v8 and then get a conversion, fuel system. I think my biggest thing is how to use the donor cars cpu as it won’t have all the bells and whistles of the 06 car. Basically need it to run. Any help with this would be awesome,
Thanks!

I would spend some time reading over the sub forum link in the last post. Plenty of info there.

I know what I need to make my 5.7 run using a 2010 Ram PCM, but kind of fuzzy on the '06 stuff. I would bet that if you ran the right power and ground wires, it might be enough to make it run. Only tricks I can think of is you will need to wire it up with a ASD, fuel pump and starter relays that the PCM can control. Then run the starter wire from the ignition switch or button to the PCM. The trick there is the PCM wants to control the starter or it won't fire. But I could have that wrong some.

There are other minutia to contend with, so much reading is in your future.
