The car should perform slightly better with a cast crank because it has less inertia will reduce front end weight. The OEM or SCAT/MOPAR cranks will withstand some severe abuse.
not if it's cast steel...density is the same...a nodular (ductile) iron crank will be about 10% lighter, so you're saving about 4 lbs....which won't make much difference...
for that stroke, unless he's planning on making like 700HP, stock will be plenty durable.
