I'd heard about them, now I've seen one.

I'd heard of the half-moon on early 390s, but hadn't had a chance to see one until now.

I wonder if Ford changed the drill-bit angle on later 390 cranks so the flange would no longer need the half-moon (I doubt it). Maybe it took a year or two for the engineers to realize the extra machining step to cut the moon was unnecessary on the new-for-1961 390. I'll have to look into this further.

Thanks for the link.

Shoe.
