Like I stated before, I'm not saying you are wrong, just pointing out that this story has been told for years like the Loch Ness Monster story. I would think that a person publishing a book should know their stuff. ...
Keith - never took it as a 'right' or 'wrong' thing
Just after a few years of saying that the 'ol 010 "story" is a bunch of bunk I thought I might take the opportunity to elaborate a little
As far as the "would think that a person publishing a book should know their stuff"
Have you read some of the Camaro books written by some 'experts
Certain authors are better than others - but let's just say that some of them don't let facts
get in the way of getting their book out to unsuspecting subjects on schedule
Even guys like Jerry have made mistaken assumptions in their publications - but
, he also makes every attempt to publish corrections in newer printings of each book
- some others haven't ...
I issued a challenge (quite a while back) to some questioning this information to find anything
in print (or published information) issued by the any of the GREAT Chevrolet engine guru's - like Bill Jenkins, Smokey Yunic, Rick Voegelin, et-all - or anything from GMP/Chevrolet Racing - that gives this explanation of the casting identifiers. No one has come through with anything I've seen
I never even heard anyone state that the markings meant something about the metallurgy until the late 90's or early 2000's - I have no idea (well, I have some
) who even started espousing it - must be one of the "Inter-Nets" thingys
If you just think about the process flow - After the cores are assembled and banked for iron pouring the line workers can not see into the mold to check for identifications internally - so they just pour the materials furnished through the mold line supply system into the scheduled part number molds on the line, they didn't know the final assembly state-of-tune at all, just the production part number for that casting ...
I was told that there were actually 'special' metallurgical blends at times - but all of these were very early production castings (pre-70~71) when the '010' started to show up in castings ...
And none of these 'special' irons were ever intended for production casting use - they were test alloys for engineering purposes and were used in assembles that were carefully tracked by GM for decisions in production.
I received a PM years ago saying there was a good posting on NastyZ (I think?) from a GM guy also stating the magical 010 info is bunk - but truthfully I never did search it out
I was already convinced this 'common-knowledge' was wrong way before I heard about that thread ...
I am a firefighter ...
I always wanted to be a Fireman - maybe when I finally grow up
