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.
Permanent molds provide dead accurate port positioning. We do not need to make our ports and runners undersized to allow for core shift. There is no core shift with permanent molds tooling. Every manifold we make 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. Do the installation once and do it right. 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 single plane manifold for small block Chevy, this manifold outperformed every other manifold. Powered by SixBit's eCommerce Solution.
