1963-1965 Nissan 411, 1965-1968 Nissan 520, and 1968 Nissan 521 HP-Series Cam Bearings by King Engine Bearings
King AM-Series main bearings are recommended for street or marine applications. These crankshaft bearings have superior embeddability, which provides greater macro-particle to reduce scratching of the crank journals and tearing or weakening of the Babbitt overlays. King AM-Series main bearings feature tolerance control up to plus or minus .0001—and they're lead-free, making them environmentally-friendly and user-safe.
