That's good advice. I'll top the oil level again once I have 500 or so miles on it. I assume it will take a few drives to dissolve the grease enough to permit oil to flow through the outer and into the inner bearings.

You know the original HO52/72 service manual (circa 1946) simply said to soak the bearings in engine oil before installation. I wonder if the oil level changed over the years?
