How can you tell if a crankshaft is forged?

How much power can a scat 9000 crank handle?

The scat 9000 cranks are supposedly good to 500 hp but theres likely to be a significant margin of safety in there. I think the more likely place for failure is with the high piston speed on a stroker… the piston or rod is more likely to come apart above 6500 than the crank!

What is the highest hp on a SBC nodular crankshaft?
