I think on one level his expert is correct in that “new aftermarket” distributors, carburetors, and manifolds are for the most part junk.
The way to rebuild and keep these workhorses running is not about parts changing with new but about rebuilding original parts and or finding what parts are interchangeable, some rebuild workarounds, and even upgrades to factory parts to achieving that reliable engine.
This website is full of examples, and people, who know how that is done and are willing to share expertise.
