3rd gen Hemi ETs

I came into possession of a 2012 5.7 from a 1500 ram with a bad #5 exhaust lifter and damaged cam lobe so I was thinking of a 392 cam and springs and keep the rest stock for now. I want to just get it running and sorted with the factory fuel injection and a833 4spd.
I have also considered buying a 6.4 pullout, cam and carb it just to see what kinda et's I could get out of it
