Perfect example here:
"Very rare & Hard to find 440-mag Engine with a steel crank, out of an 1969 camper bus.
It still has the heads, valve covers,water pump, carb, exhaust pipe that I cut at the back of the block,
oil pan still on it, the freeze plugs are still in it!!
It was in a fire. but the engine block is good. this block is worth about $800 dollars!
so make me an offer, these blocks with the steel crank are VERY,VERY! RARE
I live 5 miles s/w of richmond mo. I could bring it to you, if you are not to far away
