Will I break this crank?

All of the cast crank issues I have seen over the years revolved around the a few years of the Eagle 4" cast crank. Scat didn't have the same issues. With that said, I have run both an Eagle 4" forged crank and a Scat 4" forged crank with no issues....my current low 10 second engine uses the Scat forged crank.

My point being, if you are throwing big money at your engine, why not spend a few hundred more for piece of mind....and, as my dad used to say "If you can't afford to build it right the first time, how are you going to afford to rebuild it when it breaks?".
