Default 428 Flywheel Issue, internally or externally balanced??

Hello guys, happy holidays! I'm half way thru a Factory Five build and plan to install a motor that I bought on craigslist a year ago. As advertised, rebuilt 428 with receipts and paperwork. It does not have a flywheel or clutch and pressure plate so that's where I'm stuck.

The question, this motor was balanced during the rebuild, but I understand that "all" 428 are externally balanced, which flywheel? I'm stuck! I don't know which crank, etc, this motor has so the next step is tough. Pictures attached......and thanks in advance for any help.
