EFI Selection and planning.
The path of least resistance:

Comes with everything you need out of the box, PCM is unlocked and it doesn't care what transmission you mate it with. Can be programmed via HP Tuners. Would require you to wire some items to a relay board, which is not a bad idea in itself if you are planning your own switches and toggles. Works well out of the box and if you are going with a fore drop in in tank, this will support the LV kits from HHP.

If you were doing a 6.4 or 5.7 build and wanted to boost it, this would be it. Would have everything you need. Hidden magic, getting it to play nice with the Hellcat S/C bypass, maybe
@Marc W can spill the magic beans on that, not even the Holley forums delve into it. For the money it's not a bad start if I had a 6.4 block or was going to turbo charge the 6.2
The journey begins here:
https://documents.holley.com/efi_selection_chart62914.pdf As configured I wound up here:
Some differences from the DragPak edition. There is no throttle body on the DragPak, so no dual throttle body cable is required. Comes with two widebands as well, as I have it configured I plan on only using one (and guess what, tuning with one is perfectly fine).
So I am torn between Hellcrate and wiring everything else up manually to a switch panel (would be a fun project and save a ton of money), or get a Dominator and take the hit on cost up front.
My only issue with Holley at this point is that the price for plastics and connectors is astronomical. Not to mention there is no eta on backordered ignition harnesses so I could be in limbo well into 2024...
