Will I break this crank?

I'm just going to say this:
for every 500 times i have heard of a crank braking, 499 of then were cast Eagle Cranks. That "one" is just about any other crank out there.

Take all the advice about protecting that stroker crank.......
My self i have a forged everything, 13:1 compression motor that i only twist to a whopping 5800 rpm
