Before "Direct Connection", there was "Hustle Stuff", which was about 1965 or so. The orig DC was in about 1967 or 1968. Seems like HS was Plymouth and Dodge had something similar but with a different name? DC replaced them both.
When I started going to Mopar Nats in about 1988, it was a new world for me. Especially being THAT close to the DC main operatives, who had a well-attended seminar/Q&A session of what was is the pipeline for new DC engine stuff, or later repro program items. Plus that, back then, they sought to go back to the orig vendors (who made the items originally) to get the items built, when possible, by the latest versions of the orig blueprints. Great Times!
Certainly, the re-born DC will be the modern version of its prior self. Which might ultimately involve tire-smokin' EVs, as Dodge has already said they will be building in the future (should be a YouTube video of that commercial, somewhere).
Happy Holidays,
