Let's Talk

Specifications

Summary:

  • Airflow: over 500 cfm
  • Weight: 82 lbs
  • Injector Location: Inside Valve Cover
  • Material: Billet (solid block) of Aircraft grade Aluminum
  • Oiling system: built in to the valve cover

Full Specifications:

  • Port design by Dave Bamber. High airflow combined with high swirl has produced very impressive performance!  Customers have been impressed with the performance over a wide rpm range.
  • Designed for maximum reliability, and light weight.  The aluminum alloy and heat treat have been carefully selected for maximum heat transfer, strength, and crack resistance.  In addition, the design has been optimized to eliminate hot spots which eventually lead to soft spots and/or cracking.
  • The injector is inside the valve cover for optimum location, and a very clean look.  Bulkhead connections are made in the side of the head, so the valve cover is easily removed.
  • The oiling system built into the billet valve cover is simply connected by an o-ringed connection when the valve cover is bolted down!  No need to disconnect / re-connect oil lines.  In addition, the perimeter of the valve cover is sealed with an o-ring rather than a gasket.  Similarly, the intake flanges are sealed to the cylinder head with o-rings.
