450 to 500 hp 4 speed crank choice

I would like seasoned opinions on crankshaft material choice for a 450-500 hp 4 speed. Big clutch and 275 drag radials am considering a 3.58 stroke 340 . My question is would you feel good with a high-end cast crank like a 900 series scat or would you just bite the bullet for forged and never look back.
