455 nodular crank
#3
Really?!? I thought only a small percentage were nodular... or is that just for small blocks? I also didn't know an iron crank could be both "cast" and "nodular" at the same time. Guess I've still got some homework to do...

Yes. Really.
Common misconception. Don't believe everything you read on the internet.
Wouldn't all, include 260, 307, 350, and 403?
Nodular iron is the material that was used in all 260 to 455 Olds V8 cast cranks, just as steel was used in all forged cranks.
The legend of the "N" crank, came from the same source that bought us the solid main web 403.

Vito, to add to Norm's info I found this link for you from Wikipedia which explains nodular iron. I would add, if they can afford to use it in construction applications like plumbing, it probably isn't too expensive to use in automotive applications as well. As Norm commented, it is just another one of those modern myths.
