There are four things to consider when looking at cranks. Power level, RPM, and time spent at high rpm, and any potential shock loads such as a manual trans car, or nitrous. Cast cranks will stand up to high power levels and high rpms. Do it for any length of time and the crank will want to bend and eventually break. Shock loads on a cast crank can actually bend it, leading to failure.
