Pieces of steel in cylinder??

send pics of cut open oil filter
just for giggles send the oil for analysis
lucky you did not loose the block, the crank, the heads
I would not reuse the cam without a touch up
I guess you could reface the lifters and take them apart and check
timing chain is toast, no way to really clean and may have rotated with crud
time for a new set of long brushes
I' redrill the block mains to 9/32 or a little under then I ream
(I've found broken factory drill bits in high mileage 440's- oil going around the flutes)
(I've found passages that were not drilled all the way through- factory resharpened the bits once too many times making too short)
