Rattling down under after rebuild

I just finished going thru my 92 460 and after 100 miles or so I have a rattling in the lower end in fact I can feel it rattle on the rear of the oil pan. The rebuild included a crank grind, new bearings (10 under) rings etc. Motor runs good and oil pressure at idle is at 40 and at cruising is around 70. Obviously I have to drop the pan and outside of making sure the pump and oil sump is on tight what else should I be looking for?

Make sure the flywheel bolts aren't backing out.

Those bearings hopefully are .010 over rather than under.

.010 on the crank would be under bores go over, you are taking metal off so you need smaller bearings.
