Ford's River Rouge plant

Notice the RPMs during the dyno run? It was running at 4,500 RPM, that should answer the factory "redline" question.
 
If anything, this should also answer my crank shaft question. If knocking them over to break them from the mold doesn't bend them, not sure what would.

Loved it. Thanks for sharing.
 
Every time I watch this I see something else.
Maybe memory loss has something to do with that.

On the crankshaft casting...here's a detailed patent on the process shown:

There is incredible detailed work in there to get a set of cranks as close as possible to design with a minimum of excess to be machined away. They even cured a warping problem by casting the shafts warped the other way so the natural warp returned it all to straight..
Remember, the whole cast crank thing was a revolution when introduced.
 
Yes, thank you. I've seen this several times, but enjoy it everytime I see it, I too learn something different.
