But its okay to grind a GM crank as much as 30/30 or even 40/40 without needing to be re harden?

this has much to do with how and who made the crank some are not threw case hardening if was done and if just gased nitrided some cranks just grind it only 010 you are past it. so after you have to make your mined up to regas the crank or run it with a soft journal or put it back the way it came cutting any thing past 030 on a cased hard crank your going to want to check it
