So some more progress on the engine. I finally got the very stubborn oil pump out and ran into a sketchy fix for one of the pipes. I also got the timing cover off and found that one of the gears looks to have been replaced. They both seem to be in good condition. What worries me is that I noticed number stamps on the caps and connecting rods that didn't seem to match up with each other or the right cylinder. I also see that on part of the crankshaft it says GM 261? Here are some pictures
