Safe undersized cut for rods and mains.

They make bearings up to .060 that I'm aware of. I'd run them and never think about it. Most crank kits you get come with anything from standard to .030. Cast or forged, I'd run hell out of it.

Consider this. When people turn down the mains on a 440 to go in a 400, that's a .125" cut. I wouldn't sweat it.
