74 Dart 360 Sport

8HP70 is looking like a possibility on the transmission choice. Turns out JVX makes an adapter plate and I can balance it accordingly. I can also get a transmission controller for use with it and the la 360. Will have to use HP tuner to get shifter points changed out a bit and enable the paddle shifter or floor version.

Pretty sure you will need an aftermarket controller from Sound German Automotive. HPTuner makes it sound like you are going to try and use the OEM stuff and as far as I know that isn't possible without the G3 PCM to go with it, if at all.
