LA - Cast cranks ( Dont throw away )

Oh, it has to specifically be a 318 crank? Not just any LA crank like for 360? I have a 360 crank.
Im sure any crank made by Chrysler !!!!
Not Daimler Chrysler is top quality
I seem to remember a man named
Joe Sherman who used to turn some Chebby 400 cast cranks well over 8000 rpm .
