I just pushed the piston down in the cylinder and pulled the spun bearings out...Here they are:

That looks pretty stepped, have you had a chance to mic it yet? Kind of get some idea of how it is.

No I was just foolin around out there, I'm gonna hit it hard in the AM. When you said stepped, did you mean the first pic? The first pic is with the bearings still on the crank, they just rolled.....so hopefully thats my spun bearing right there.

It's hard to tell from the pics but in this one I think I'm seeing a step in the journal, just after the fillet. It should be a smooth transition from the fillet straight into the journal area, but it looks like a step in it.

EDIT: Here's a quick paint, pointing to the area I was talking about.
