The 6.4 Hemi has 16 spark plugs and requires special 5w40 synthetic oil that can be hard to find.

If your looking for simplicity I would stick with GM's 6.0.

Hard to find? Special?
The oil is common in modern cars and is available at every Orielly's. The spark plugs last a long time and are not the expensive variety. Infact, they are quite cheap compared to many of the exotic plugs used in some toher engine makes.

OP, I have a 6.4 in my Challenger SRT and while it is a different tune, it's a beast of a motor.

The oil that the 6.4 Hemi requires that carries Chryslers rating is only made by Pennzoil the last time I looked, and not every parts store carriers this oil. Even Mobil 1 oils don't carry Chryslers oil rating.

Also if you idle these trucks a lot the plugs don't last 100k miles and if misfires start to occur you can kiss your cats good bye.

You need to read the manual for the 6.4.
The oils that Orielly's carries Does carry FCA rating along with several other brands of vehicles and engines. That aort of thing is just not a big deal anymore. Ford and GM have the same stipulations. It's very common and not a big deal anymore. Every Oriellys has it. I've persoanlly bought it at several of them.
To clarify; One does NOT have to buy oil from FCA to maintain warranty and that is per the manual.
Plugs dont last and kill converters? Where are you getting this nonsense? That was possible in the earlier days of cats but it's rediculously improbable in a new engine.
No, a misfire or lean condition in these sophisticated engines results in power derating, messages on the dash and nothing more.
Spark plugs go for $3 to $6 - not a big deal. All easy to get to as well.

I looked on OReillys web site and their in house brand does not include a 0W40 oil. Again the only oil that meets the MS-12633 Chrysler spec is Pennzoil and maybe Scamz oil if you can believe their marketing hype.

This guy knows

Misfires are more common on trucks that are worked hard and idled a lot which sounds like what the OP does with his truck.
