I thought the LS3 and L99 shared the same spacing? I only see one water pump part number for all 6.2L Camaros.

EDIT: GM only lists one water pump, same with RockAuto. This leads me to believe that the L99 and LS3 pump are, in fact, the same pump, with truck spacing.

ACDelco 251734 / GM 19207665


I can definitely confirm the mechanical fan would most likely hit the outlet:
