318LA Myth's still being created!

Cast cranks were phased in around 1970/1972. All original 273's and 318's had forged steel cranks till then. You would not put a forged crank in a 273 and cast crank in a 318. I have a basement full of forged steel 273 cranks. Guess how many cast cranks are down there? Chevrolet also made a running change, based on year, from forged cranks to cast cranks. They were cheaper.
