it looks to me like an attempt to balance??
the grinding is on #2 web

That minor amount of grinding wouldn't hurt anything in my opinion I would use it!!!

yeah, the owner wants to use it. all the bearing surfaces are perfect. it magnafluxed good. i think it will be ok.

Ford, many times cast the components like that in multiples to save time. They had to be broken apart out of the mold and then they ground off the rough broken and sharp edges like sprues and casting flash. I don't know if that's what it is but it could be. Ford didn't try to make them pretty when they did that but at least they were presentable and still worked OK.

Find a Sunstrand balancer & have it checked.

Is it possible that that was done to balance the crank? That’s what it looks like to me.

 

[stevests]

Sure was, most likely !

Looks like the guy who was cleaning off the flash on the forging got a little heavy handed with the grinder.

When they balanced them at the factory i think they drilled them and weighed the shavings. As said it may be from cleaning up the raw crank.
