Fitment and Ordering
This is the standard-size 8B663HN-STD version, not the .001-inch undersize or extra-oil-clearance version. Match the part number to 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.
