Fitment and Ordering
This is a standard-journal-size, extra-oil-clearance set, not a crankshaft undersize set. Match 8B663HXN-STD 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.
