Having the wrist pin intersecting the oil rings has absolutely nothing to do with oil consumption. If it did, then every 347 on the road would be using oil....as well as many other longer stroke engines in other engine families. It's a wives' tale and it's one that gets my goat every time I read it.
Oil consumption can come from several places and it doesn't have to be piston ring issues. Valve seals can wear out, valve guides can wear, PCV valves can go bad, intake manifold gaskets can leak.
Some careful investigating will let you know where it's coming from. I'd start by pulling the carb off and seeing if there's oil laying in the plenum. If so, then it's probably something like a bad PCV valve. If you see oil on the intake valve stems, then it could be valve seals or guide wear.
