Certainly a light rotating assembly is a help. We did this out of necessity and budget. No aftermarket forgings were available, only an old 990 crank if you could find one. Billet crankshafts were not an option for us in those early days. We ran what we had and we had 3-4 N cranks. With all the options we have today, I would never run a cast N crank to 1000 HP. But I wouldn't be at all concerned running one to 600-650 HP with nice steel rods and modern pistons.
