440 steel crank upgrade

Hello Cuda1979 How Much horse power & torque are you trying to get out of your build and what kind of driving will you be doing ? all street ? all track ? if your building a street car with some track use, then your cast crank Will Suet you just fine,

I'm pushing well over 600 HP & 600TQ on a Cast Crank with LY Rods, going on 3 years racing this Bad Boy on a Trans Brake Leaving at 3000 RPM shifting at 5000~5200 RPM Running 10.36 @ 129MPH Yup Cast Crank Baby !!! Oh and forgot to mention, including a 250 shot of nitrous with a Progresser.
Are you still externally balanced or did you (can you even) concert the cast to internal balanced?
