Your money so you will do what you think is best , heat treating a cast Iron crankshaft only buts a surface hardening on and and wont make you crank any stronger or last any longer , its the flex in the crank that brakes them and the only way to remove most of the flex is going to a stronger metal like steel cast or from billet , this doesnt mean they still dont bend and flex they just do it less and can take more to a point , they can still brake

With building dozens of race engine a year for over 20 years I have tried heat treating , nitrided , cryo etc etc , they dont work but thats your call to find out just trying to pass on information from something I have had customers try many times and it failed
