Factory LT1 Intake Manifolds

Before we ever ground the first chip on the LT1 Cylinder Head , the thought process was already in motion on how the manifold had to interact with the head to make this combination make the most available power. Emphasis was placed on having a broad power band, and on making as much torque as possible so these heavy F-Bodies can get down the track . We have come up with a design that does not lose any flow when the when the manifold is bolted to the head. ( most cast manifolds will show a 8-10% loss ). We were able to do this without wrecking the original power curve of the LT1 engine.  These manifolds are the perfect compliment to your newly ported LT1 heads . You can also rest assured knowing the were developed hand in hand with the same heads you just had done. See below for use with other ported heads.
