The cam bearing is interesting...

I had a number of shops look at it, and none of them found any issues with the block itself, but they did find issues with our oiling system. We suspected this is why we lost a rod in the first place and repaired said oiling issues. But, time and time again, it was checked and nothing in the block was found, yet we still lost pressure only when hot. After months of getting no where, I finally decided to go and just buy another block and see....We put all the same parts in that block, including our oiling system, and no issues other than my carb went a lot leaner with this one.

It sounds like you found more than we did. I paid a lot of money to different shops to look at it. Not to mention my time putting it in and taking it out of the car probably 10 times. I really wanted to believe we had a bad oiling system or somthing not related to the block, but if you found somthing, that's a good thing...We never found it.
