#1 and #5 rod bearing spun for sure. Initially I thought it was likely due to a clog. Now, I'm wondering if it's do to the engine's slant. It is off level with the front higher by about 5 degrees, maybe less. Could this be the reason? I'm thinking that if the oil pump is functioning properly that it should not matter, I'm just wondering.

Nothing to do with slant. Consider oil starvation due to low oil level, high volume pump in stock pan(lack of volume again), too much rpm for old parts, rods out of round or stock bolts relaxed.

How fresh or old was engine?? Stock or rebuilt? What modifications if any?? Mileage??

honestly, I don't know much about the engine. Was told it had 10,000 on last rebuild. I'm not all that broke up about the spun bearings because I was planning on a rebuild anyway. Looks to be mostly stock at anyway, except for the edelbrock intake manifold that I put on.
