It was Ford's practice in the day to let cast iron parts 'cure' for 30 days prior to machining. Since my early '48 8N engine casting code shows I167, the code breaks down as I = September; 16 = day of the month; and 7 = year/1947. Adding thirty days to the 16th of September puts the date at October 14, 1947, the day that my 8N was more than likely actually manufactured. This date is also an important date in American and World aviation history as it was on this date that Chuck Yeager broke the sound barrier flying the Bell X-1 over Mach I. Interesting fact that I can now brag about...
