Fitment and Ordering
This is the .001-inch undersize version, not an extra-oil-clearance bearing set. Confirm 8B663HN-001 against your specific Chevrolet crankshaft and connecting rods rather than selecting by engine family alone.
Verify journal dimensions, rod housing dimensions, bearing width, and assembled oil clearance during assembly. Contact 3V Performance for help confirming application and sizing before ordering.
