Will I break this crank?

I'm doing the same thing with my 408. 475 to 500hp and a 100 shot. I have a controller so I can ramp it in. I researched it a lot. Many sbc and sbf claiming running 300 shots on the scat 9000 cranks without a problem. Some going over 700 hp. Some big blocks over 800. I think a mopar crank should be stronger because of more overlap. I figure the crank is stronger than the stock block.
