Features Unique to All Models for Continental Engines


       Improved Casting Integrity

  • Castings meet stringent porosity and shrinkage requirements.
  • Promotes a longer-life cylinder head, less prone to cracking. 
  • Computer Generated Cylinder Head Fin Configuration .
  • More consistent fin thickness and spacing.
  • Means more uniform heat transfer and fewer "hot spots", compared to standard factory cylinders. 


      New Materials

  • Advanced alloys yield 20% greater strength than aerospace industry standards for air-cooled cylinder heads.
  • Increases cylinder longevity.


      Through hardened 6382 Steel Cylinder Barrel

  • Through hardened 6382 Steel Cylinder Barrel. These barrels may be ground oversize and fitted with oversized pistons.


       Choked barrel

  • Optimal barrel choke allows rings and pistons to work properly at normal operating .
  • Improves performance and reduces ring and piston wear.


       Features Unique to Continental 470/520/550 Engines  

      New and Improved Rosan Inserts for Exhaust Studs (520 & 550 models)

  • Improves exhaust union reliability. 
  • Stronger Injector Boss. Increased thickness has been added to the injector boss area. Helps reduce cracking. 
  • Strengthened Rocker Boss Area. Thickened web size reduces cracking.  
  • Increased Port Wall Thickness and Enlarged Spark Plug Boss .
  • Exhaust wall thickness has been increased to reduce premature warping and resist cracking.
    Improved Port Design
  • 7% better volumetric efficiency
  • Smoother port walls reduce drag
