it's that the Metallurgy was ****.
You can put 550 -580 through a GOOD cast/nodular crank and it'll hold up.
After that...its like tap dancing in glass shoes.
Scat is quality and so are ohio crankshaft & mopar cast cranks, all known to take abuse.

Not if the damper is junk. A junk damper will kill any crank in short order.
