if the tolerances end up being too loose in a new pump, the edges that ride in the bore are too rough, I wouldnt want to put it into a good pump with a known good bore like your incoming one because its all bured up and scratched and those metal bits probbaly scored the pump itself in my situation here. but a good example ofwhat you hope NOT to find lol

And this is a rod cap. I don't have a clue what any of these mean and google hasn't helped me yet.

Generally if the crank has been turned it will be marked on usually the first counterweight with how much it has been ground. example there will be like M .010 R .010 stamped (denoting how much the journals have been ground) into it somewhere. Bearings that are oversized (for an undersized/ground crank journal) will be marked as such with a corresponding .010/.020/etc. There's a good chance those are the factory bearings you're holding. The only way to know for sure, if you have any doubts, is to mic the journals for a measurement so you can order the appropriate bearings. More pics are better if you have any more questions.

I created a thread so I guess I should send folks to the link instead of having two places I asked the question. I posted a pic of the crank where it was stamped. Follow it over there and I will have more pics there. https://www.gmsquarebody.com/threads/help-identify-these-bearings.35305/

Installed a new electric fuel pump relay with a key-on 3 second prime. Whoever installed the engine had the fuel pump wired direct to ignition source. No bueno setup. Not safe.
It works as intended. It’s similar to this one.
