      I know the VVT engines have different water pumps, and the L92 has the huge intake.

      If it has not been modified, it should look like the first pic.

      LS3



      L92 (Should be the easiest to spot with the intake and VVT truck water pump)


      L99 (underneath should be the same looking intake as the LS3)

      Cheers for the info, looks like i have an L99. Might have to take advantage of the vvt.
