2016 6.4 srt in 69 dart

I'm looking at putting a 6.4 in my 69 dart, it's an srt motor with all the stock wiring harness and ecu. I know I'm going to need headers and an oil pan, I plan to run a th400 with a small block 727 bell housing. Besides a tune and probably a programmer, what else will I need? I'm just getting into this and there's so many different things I'm reading in trying to get a handle on what I need, not what everyone else needs.
