I agree Bob - I said that it was difficult ( as reinforced by the small number of instances that it happened) but not impossible. There were two Saginaw Foundries producing iron castings (one gray and the other ductile). Saginaw gray only ran two shifts and V8 blocks only ran at a rate of about 2500 molds per shift. The technical point is that you can tell by the casting clock if it was even possible for a specific case to make it to Flint in time for machining on the same day. For example, there's no way that an 11:00pm casting could get through processing and down to Flint for complete machining in one hour! I worked at Tonawanda, but traveled to our sister plants in St. Catherines and Saginaw quite a lot.
