So I am putting my motor to gather and I want to know has anyone here ever broken a stock crankshaft in a 4.6 2v/4v? And if so at what HP where you at?

I was wondering the exact same thing a while ago and could not find anyone that broke a stock cast crank. I think because many people just swap it out to the forged crank once they are building the engine.
However, you can do a budget build now with the oem coyote rods and a decent forged piston. My plan is to use the stock cast crank with these parts and push to around 600rwhp. I think if the rpms are held down to a reasonable level (6,500), the engine should live.
