Enrique,
 
You are not dreaming, I have to pinch myself sometimes as well.  No, Edelbrock was not interested when we called them so we did a lot of footwork and visited two foundries in LA to settle on Foundry Works Inc.  They designed & cast the original Bob Walker HEMI manifold from which we patterned our New Poly Air Gap 4bbl. (with Bob’s permission and blessings – nice guy!).  This foundry is not just a bunch of guys pouring and making molds; Javier is a lifelong Mopar guy (his company car is a 1969 Super Bee) and engineer.  He also developed and cast the Arias aluminum HEMI heads and has worked with and for some big name racers in R&D.  His expertise at building the "proper” intake manifold by considering the required cross-sectional/taper and runner volume to produce the appropriate intake manifold CFM flow (310-270CFM) for our engines (proper plenum/runner pressure throughout the manifold is also critical) made him the sensible/right choice for this project. 
 
Secondly, upon subsequent phone conversations, he is excited (truly – only a guy with a Mopar heart can get past the “business” end of things...) to cast a set of High Perfomance Poly aluminum heads for us!  Of course we need to sell enough intakes to pay for the sizeable cost of that project before we consider casting New High Performance aluminum Poly heads. 
 
I guess the bottom line is if we can generate enough pre-orders to pay for the Air Gap manifold project then we (or I...somehow) will launch the High Performance aluminum Poly heads project.  Many of us have been “talking” about an aluminum Poly manifold for some time and now the “time” has come.  Roland Osbourne of Chrysler Power Magazine is on the hook for this adventure and I am doing what I can to make sure this manifold project comes to fruition – lots of hours but then again, I work for free.  I don’t see the Poly Air Gap 4bbl. manifold project as some entrepreneurial deal but merely offering a cost-effective alternative to the overpriced E-bay Weiand and to provide a truly superior intake design for all of us “Polyheads.”  Our “better half” may not see it this way, but the joy is in the journey and the fruit of our labor will be smoke pouring from the wheelwells.

WOW Please tell me I'm not dreaming, am I reading this correctly? I'm assuming this is Edelbrock?

> Yes, we will have injector bosses cast into the New Poly manifold. A Supercharger will work with this high flowing Poly intake as we are building sufficient runner length and cross-sectional area to flow approx. 315CFM â€" 270CFM to accommodate High Flowing cast CNC ported Poly heads we have. Additionally, I am working with an engineer to create a set of HP Poly Aluminum heads should we have sufficient orders and success from our New Poly Air Gap intake introduction.
> The prototype HP Poly aluminum head with be totally redesigned for sufficient flow characteristics to sustain 600HP+ with thicker port walls to allow for increased porting of MAX Racing venues, redesigned water jackets will provide the added wall thickness to alleviate the “whoops â€" I ported through it†as well as increased bowl thickness, redesigned dual quench chambers, spark plug relocation...so I hope all the “Polyheads†out there and new enthusiasts will become energized to make all these projects reality.

Valve timing based on port flow. etc. As much as I like the idea of a 392 poly I also like the sound of a 331 so I'll be playing with different bore/stroke combos on my dyno sim. Likely be looking for 3.54 rear end instead of the 3.91, too.
