		| All FE cast cranks are made of high nodular iron. |

		If you've got a 390 crank, it's just as strong as any other 390/406/427 cast crank.  Ford only used pearlitic nodular iron with an 80,000 PSI tensile strength in all cast iron cranks.  It's a standard "crankshaft grade" of cast iron.
  Nobody makes gray iron crankshafts for use in engines, as they are not durable enough.
  If the crank magnafluxes OK, then you've got a solid crank to play with.
