I have a 67 440 that I was told had a forged crank, it has a forged crank dampner on it ( thin round dampner ) but this crank looks like a cast crank to me. It's been a while since I've seen a factory forged crank so I'm not sure if it is or not. Does anybody have a picture of a forged 440 crank? or know of an easy was to tell?
