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

Nitrid won't work on these cranks anyways. Thanks for the info but yes I will still try tho.
