We (NCRS) have documented a number of Flint small-blocks that were cast and assembled on the same day, and MANY that were assembled the day after they were cast. The Saginaw Foundry sent 55,000 iron castings to Flint V-8 every day, and those dedicated GM trucks ran 24/7. Machining at Flint V-8 ran on three shifts, and both assembly lines ran on two shifts (170 per hour on Line 1, 130 per hour on Line 2).
