Have been unable to locate what sort of steel that the 327 steel crankshaft has. (small journal) I have one that I  might chop up and  throw in the :devil10:forge. 

 

Read somewhere the 427 had around 1053 or 1055 ish??    many  of the newer ones are listed as 4340 nickel chromium molybdenum alloy.

 

So anyone ??

They are a 1010 alloy. All SJ 327 cranks are forged, and were the preferred crank by many racers back in the day.
