Crank breakers wanted

I had a '73 400 cast crank I had taken out of an engine that had spun the rod bearing and was grooved out beyond repair. I had some use out of it as a "hammer" while playing a game of Chrysler Vs. GM and Ford by throwing it at other pieces of junk cast iron from a height of six feet. It broke everything I threw it at without itself breaking and left some pretty good chips in the cement, too. The '73 360 crank I have right now sounds like a forged steel crank when tapped with a hammer. I wish I had crack checked the B crank before hauling it away to see how much damage I may have done to it. But after that, I believe the early seventies cast cranks they produced could withstand anything this side of nitro if used with aluminum rods.
