What are everyone's thoughts on how much power a stock BBC crank can handle 650 - 700? 2 bolt mains

Cast crank= 400
forged steel=750

I ran a stock cast bbc one that was cracked in a blown injected engine that made 1320 on the dyno and it never broke, after a while i finally put a nice forged crank in

Just to clarify in case I misunderstood

You knowingly put a cracked cast iron crank in your engine? :?
