The weird mad-scientist side of my brain tells me the bearing failure was due to harmonics traveling through the crank from back-to-front. Old Henry drove with a bad u-joint for some time and on a downhill deceleration, that sends the stresses forward to the end of the line. Case in point: I know a guy who kept having his Toyota front pulley (harmonic type) come loose and ruin the key. No symptoms. Turns out his flywheel was loose. I've seen bearing fatigue like this isolated to one or two bearings but the cause was usually long-term detonation. Old Henry was always careful with his timing and jetting.
