I seem to remember that Keith Black Racing Engines can mill a billet block within about 5 hours. I believe they were using a 5 axis CNC with more than a dozen different fittings that auto loaded as they were required. One of the staff was telling us that it was nice to load a healthy sized chunk of billet into the CNC machine, then come back 5 hours later to see a fully machined block that only required finish honing of cylinder and lifter bores.
