5.9L/360 Magnum - 1965 Plymouth Barracuda - Stock Fuel Injection

Hey fellow Moparians, just got a 5.9L Magnum recently from a '99 Dodge Ram 1500. I want to go with stock fuel injection on it for my 1965 Plymouth Barracuda, got all the wiring + injectors and such to do so. I do not want to retro fit a 46re automatic in there, but would rather use either my 904 or 727 automatic. I thought in the past I stumbled on a thread on here about someone pursuing the same thing, but ended up having issues with the ECM trying to figure out what to do to the motor as the older transmission made shifts.

Has anyone done this conversion out there w/stock fuel injection on their early/later A body? Thinking of getting a gear vendors later in life too.

I've also done a 318 Magnum swap into my brothers 1965 Plymouth Valiant 200, carbureted it.
