340 oiling system

I'm not looking to run 7000 RPMs, so from what I'm reading here so far I'll probably be ok to run stock stuff. Moper's advice looks to be good for extra protection, however my short block parts are already machined and parts (including bearings) purchased. They just need checked over and if everything is a-ok, then assembled. But perhaps I will talk to a shop about these mods...

As for the used pick up, I agree common sense says get a new one, but I've seen people selling used ones and wondered if I was missing something.
