Sorry to re-open this thread, but besides this part number you mention, there was also one that said 14044807, which may or may not have applied to the 1999-2001 7400MD "Vortec" version. Both variations also have a forged steel crankshaft to distinguish them from the lighter-duty 454s in the pickup trucks.
