  • INFO
  • A great kit from Orca easily installed with illustrated instructions. Cools block only on Magnums with serpentine belts and outdrives only and center riser exhaust. For dry joint exhaust see MC336-DJE and MC336-DJE05. If you have spacers between your manifold and risers, add $35. Allows your engine to run as GM intended for best performance and economy. A pressurized 50/50 mixture of antifreeze and tap water instead of corrosive water with hot and cold engine areas allows round cylinders and constant temps. Like cancer, it can be slowed down to allow your engine to last years longer. We need photos of your installed engine, which may vary the assembly of your kit from our photo.
