  • Conversion kits for older Ford V8 'log style. Exhaust bellows, risers, elbows and engine gaskets.
  • We ships to United States, Canada, Australia and International. Standard OEM manufactured castings can have uneven internal wall thickness due to their casting processes.
  • GLM Marine uses a ‘lost foam casting ’ process, allows for more accurate casting of the wall between the water-jacket and gas area.
  • This prevents thin spots in the wall which lead to premature failure. The GLM Marine brand is also designed with a larger water cooling area, up to 40% more compared to original OEM models.
  • This can help reduce the overall temperature, leading to longer gasket life. The internal area has also been designed to prevent back pressure or excessive turbulence.
