392 Early Hemi CNC Programs Coming Soon
The 392 head has a need to be filled based on all of the phone calls and emails received. I’m in the process of developing two CNC Programs for this head – Street and Race Ports. The Street Port is based around a 2.125 intake valve size and flows 320 cfm @ .650 lift (300 cfm @ .500 lift). For reference this head peak flows around 225cfm in as cast form. This would be a good all around option for Street Rodders looking for a nice power gain while retaining the factory castings or for Blown 392’s built for the street. The Race version is much larger in size and maximized for flow using a 2.200 Intake Valve. This port is currently flowing 365 cfm @ .750 lift which is very strong for a 392 head due to the upward slope of this head design vs a highly sought after 331 head. Two CNC Programs coming very soon that will help round out my entire Early Chrysler Hemi line.
