Note 1: Conrod bearings are physically interchangable for 1500, 1600,
1622, Twin Cam, and 1800 (3 bearing) engines.  However, Twin Cam
bearings have a larger bore size for more oil flow.
Note 2: See CSM MG/309 (Main and con-rod bearings). -- Vandervell
bearings were Lead-Indium overlay, while Glacier bearings were
Lead-Tin overlay.
