Castings that are cast iron will be a bronze or copper nickel, I hope. No aluminum casting. Crankshaft will be cast. Heads, water pumps and oil pump also cast. Steel stamping oil pan can be cast since the First Flathead Ford V8 had a cast pan.
I figure to farm out threading bolt and stud holes to a CNC shop. I understand they can thread mill as small as 1 millimeter. There are over 70 threaded holes, many blind, smallest 5/16-18 in real life.
Ford connecting rods had integral studs, no bolts. I figure to get them investment cast with pre-threaded studs cast in place.
Have to find the time to eat yesterday's breakfast.
