Stock Crankshaft holds fore ???Hp

[Benjamin]

Most of the tuned GN engine gote stock crank and rods up too 600Hp but dose that work, i heard it was cast dont you nead forged crankshaft when you have up too 150Hp / litre.
I am buying a engine now and wounder if it can be daily driving whit aprox. 600Hp??? And the same question about the engine block. "stupid swede"

If i nead forged crank and beter rods where can i buy them?

I have a stock naturally aspirated 231 crank in mine and it puts down 400hp at the wheels in street trim(500 flywheel) and I have had it up to 22# of boost on race gas too without trouble.Not sure how much its getting to the tires in that setup.Still tuning on race gas but it has taken my 3650# GN with me (150#)in it to 11.69 so far with a conservative tune...lots still in it.I think with a maxed out tune it would be at least close to 600 at the crank.So,I say a stock crank will work fine deep into the 10s even a n/a one.Why spend $300+ for an engineering "theory" about rolled fillets.
