You can break a crank to pieces running a nitrous system that is not setup properly.
Also high compression engines tend to be better with a forged crank. The tremendous pounding of the piston can do a number on a crank. Also under high RPM's the forged crank will not flex as bad as a cast crank and hold up better. With the rod ratio of Mopar engines this isnt a real big problem compared to Chevy or Ford engines. Thats why there were not many 4 bolt main Mopar engines. They simply didnt need it.
