Do you know the reason behind the recommendation for the 2000 rpm break-in? I know it has a lot of proponents, but have never heard what its advantages are over the progressively-higher-load approach. Most of my 40s and 50s manuals recommend the latter approach, but admittedly they are all for truck engines with full pressure lubrication like the 270 and 302. Is the higher speed of your method to ensure proper dip-and-spray lubrication, ring seating, or ???
