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.
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
has extremely accurate port positioning. |

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. We
find any leaks before the manifold
is sold to eliminate installation
hassles for you. Do the installation
once and do it right. |

We
offer a premium hand polished finish
at a price that is dramatically less
than other polished manifold prices. |

|
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, our
52030/52031 manifold outperformed
every other manifold |
