>> Jim,
>>
>> Did you know that there are Three Crankshafts for 455?
>> There is Cast Iron, used in most passcar applications.
>> Then there were Nodular Iron used in many performance cars and in some
>> marine and apparently some motorhomes.
>> There are also some Forged Steel cranks that were supposed to go to the
>> industrial and some went to motorhomes.
>>
>> When I got my coach's engine open, it had a nodular crank, and of the two
>> salvage engines, one was noodle (an engine builder joke) and the other was a
>> cast.
>>
>> The Iron and Noodle can only be differentiated by an N on the front throw.
>>
>> Matt - whose recent rebuild survived the incident.
