Rod Bearings are Done :(
if you can feel anything on the crank by running your fingernail over the journal... i mean anything you need to have it turned...
remember that every groove has displaced metal around it...
we just had this happen on one of our hemis... a rocker arm tip came off and sent things around the engine... get all new bearings, including cam bearings...
also inspect your oil pump for issues or more junk...
