Looks like your oil pump locked up causing the weakest link to break. Replace your oil pump and especially the pickup which allowed something large enough to lock it up but small enough to pass through. Your pickup bypass may be damaged or stuck open. Do not, I repeat, do not reuse your oil pump pickup. Get a non bypass pickup from parts plus. On a 302/289 the pump drive will twist without breaking the distributor gear but on 351s and larger the gear will break. Your oil pump is trash.
