  STEEL MOLDS

   

   

  All of our manifolds are cast of aluminum in heat treated steel molds, not sand. This type of tooling is over three times as expensive as conventional sand casting tools as used by all other performance manifold companies. But permanent molds produce a far superior part with a smoother finish and less porosity.

  DEAD ACCURATE PORT POSITIONING

  Permanent molds provide dead accurate port positioning. There is no core shift with permanent molds tooling. Extremely accurate port positioning.

  100 % PRESSURE TESTED

   

  Every manifold is 100% pressure tested. That means the water jackets are pressure tested for leaks, the plenum and port runners are tested for leaks, and the exhaust gas crossover (when utilized) is tested for leaks. This is an extremely time consuming process which is why it is not used by other manifold manufacturers. We find any leaks before the manifold is sold to eliminate installation hassles for you. Do the installation once and do it right.

   

  OUTSTANDING PERFORMANCE

   

  Due to the fact that our ports are typically larger than those found in competitive manifolds, our manifolds usually produce more power and torque than others. In fact, in head to head dyno tests with every other similar dual plane manifold for small block Chevy, this manifold outperformed every other manifold.
