What do we know about the z1 lower intake manifold?

Mysilverz

So today I spoke with Russ at Z1 and placed my order for the z1 power plenum and ported lower intake manifold with a new gasket for the mating surface between the lower intake manifold and the cylinder head. The following Sunday after they come in I will install both and dyno my car at the same dyno I've used in the past so we the 370 community can get a rough idea of the gains with this mod. Now my car already has a fast intentions cat back exhaust and stillen gen 3 intake. I may have a set of fast intentions test pipes on by then as well. I'm trying to get all these bolt on on the car before my ecutek tune on the 18th. I'll keep everyone posted.
