We Designed this Manifold to be a Direct Replacement  for the Stock Manifold.   Allowing additional porting and polishing.  A engine is an air pump any time you can increase flow the better it will run.

This Manifold is Made from Billet aluminum no welds. It has much more volume than the original Manifold, especially number one and number Six cylinders. 

We designed it so the original intake plate or any aftermarket intake plate will go right on the manifold. we have done extensive flow testing and every time we use the grid heater flow is increased on the flow bench, it is only a few CFM, but an increase non the less.

The manifold comes with all the Necessary Stainless Steel hardware for Install. 

Available in many Different Finishes and Custom Engraving upon Request.
