I think the point is that up to about 500 HP you are fine with Cast. Over that you should spend the extra $500 and get forged. If you are building a 500+hp engine you have the money anyway :)
I guess my point is why risk it. And secondly, few people i know ever stop the quest to go faster.
Building even a truly 500 horse smallblock isnt cheap.
Just saying even at that power level i would go with a forged crank because i dont have the extra money to build another motor if the bottom end lets go. Maybe you do.
Through the school of hard knocks i have learned its typically better to spend the little extra to build in a safety margin and for future upgrades. I know i will never again build a stroker anything with a cast crank. It only took me once to learn that
Your results may vary.
