I am gathering parts for the Charity case motor . I Have a nice Two bolt block that will be linehoned with splayed caps , I have a nice set of Crower rods ,My next piece will be the Crank. I am on the look out for a steal crank and i am wondering if there are better castings ( forged ) or better years of forged castings . typicaly the earlier the year the better the metal. What is the optimum crank for a blown alky set up. i want a conservitive motor - so i believe a this will fit the bill . any help or input would be appreciated !
