I assume it is a SGI forged crank, and not a cast. If it was a cast crank I would throw it in with the iron being hauled off.
But if it is a forged, I think even a .010” cut might get enough fillet to look a lot better. Hoosier would certainly know. The 3.25” main is a pretty big diameter to flex and break were the fillet is missing, it should not need a huge fillet. It looked like you have some higher hp build going on, I’d look for a better crank there unless it is fixed. But on something with 500HP or less I’d take your forged SGI crank that is missing that fillet at the thrust bearing over a off shore cast crank.
If it is forged it would be easy for a shop that weld cranks to fix it also. I think you’d end up with the entire crank turned down another .010” from were it is now.
