Gravity bends a crank?

[rheltzel]

It pales by experience. If you know for a fact, based upon 63 years of building engines, that storage of a flathead Ford V8 crank in a horizontal position results in a bent shaft, I guess that ends the debate. Still, your certainty on the point does beg the issue of how long a Ford flathead V8 crank must lay in a horizontal position before it is ruined by gravity. Are we talking months, or years?
