lol.. thats waaaayyyyy to expensive for a factory crank.. k1 or bpe has forged cranks for i believe 699.. that are 4340 rather than the old forging they used to have 40 years ago..
Well said - so why ask if a stock one can do it?...lol
Turbos are not as hard as blowers are on cranks, but it's still going to twist. Get a good aftermarket one and don't look back.
