Having used quite a few 440 source cranks I have never had any failures making up to over 800 hp in a few. The problem is the machining. having to send them out to get skinned to get bearing clearances corrected and snout clearanced so dampner had correct press fit is the issue. so you take what you spend to fix you could buy a better machined crank . Never had any issues with a molnar.
Yup, about the same cost after paying for "adjustments"
