Correct. We can't tell you anything without pictures of at least the bottom end, I.e. bearing caps removed to view mains and rod journals. Also, that length of time running without oil probably fried the valve train so the valve covers have to be pulled as well. You should prepare for the worst. Only time you get away with oil pump busting is when the engine is immediately shut down. But good luck and more pics for solid answers. Temp gauge doesn't move until 240f when coolant is really overheating so that's the good news. But a pan full of oil doesn't help the cyl heads when the pump is non-existent.You must have the oil pan off. I would suggest taking off a main bearing cap and inspecting a bearing.
Any obvious scoring or pits to the crank journals? That's the most important as the crank may have to be machined then obviously bearing sizes change. You should focus your attention here before ordering anything.So here is the front main. I'm assuming I'll need new main bearings and rod bearings. What else do I need? Thanks.
