Product Information

We offer 2 stages of porting, each with its own level of modification.  Before we go into detail, it is easier to explain the applications first.  Stage 1 is best for a Stage 1 3400 or 3500 upper.  If you have a 3500 upper, going Stage 2 makes the most sense, even if you use a stock 3500 upper as a short term budget restriction.  Stage 1 is based off a 3400 plenum gasket, and Stage 2 is based on a 3500 plenum gasket.  The lower to head gasket is the same for both (more on this below).  We do not gasket match to these plenum gaskets, as the shape is not optimal for flow.  We use the gasket as a limit to the port size and make them the best shape for performance.

Sportsman series lower intakes are sized where we want them and then blended to the rest of the runner.  Competition series are fully ported from both ends for the most flow possible from this intake manifold.  

Powder Coating is available in many colors.  Please use the additional info field to tell us what color or contact us first to discuss your needs.
