440 steel crank upgrade

Yes, but y
Thanks. I just wanted to know because there are a few 440s with cast cranks close to me but I didn’t want to buy one if it could not fit a steel crank. Are all the steel cranks internally balanced?

Yes, but you'll have to have the assembly re-balanced and change over to a neutral balance damper, flexplate/converter/flywheel, as the steel cranks are generally internally balaced, while the cast are external. Hence the need to change the damper/flexplate etc.
