That sounds sweet! definintly interested into geting one of those! If design is an issue, perhaps designing it after the LS6 or Fast intake could help with the plenum. I see LS7 are now using rectangular ports for the intake...
Next thing that would be cool if it could happen with the LTx is design a set of LSx style heads for it and allow it to use LSx intakes? I'm just talking out my *** now but would bee could to see something like that.

I'd say you have a pretty good following, and this is just from one forum, and the list of people interested keeps growing.

We saw the bulk of our gains in the mid range. The top end picked up also but only becuase we could finaly flow enough air to feed 400 cubic inch's 
I’m subscribing to this thread.
If hot oil splashing on the underside is a concern, you could hang a shield or plate of some sort? Just a piece of sheet metal with a half inch between it and the bottom of the manifold should protect it from the heat.
I’ll agree with the fuel rail concerns. While I would pay more than $400.00 for this setup and go for a new fuel rail system, some guys would want to keep the stock stuff. Maybe you can make it to accept the stock rails but with a modification (to the rails) that rout the crossover around the manifold instead of through it. This will untie your hands on the crossover point.
With the right tunning length, you should get plenty of power. Be prepared to make five or six of them all different before you figure out what works best. What you calculate on paper may not work in the real world.

Hopefully this can turn into a feasible reality.
Is that a stock intake that's been chopped up?
It would be nice because this

Well, if you could make it with some sort of dual bolt pattern with the option of plumbing for GEN I TPI also you would sell even more of them. I think it would be dumb not to.

Have you ever tooled up a complex molded composite part like a FAST manifold? You are not talking 5 figures, you are talking 6 as in $100,000 and up. That's after your development costs. You can't make changes easily after it's tooled. Now divide those costs by the number of manifolds you can reasonable expect to sell in the first two years and add that to the normal selling price. At just $100,000 tooling, and 200 mainfolds, that's a $500 add-on to each. Personally I think 200 manifolds would be high.
If you are looking at carbon fiber, even hand laid up, you are talking part costs well into 4 figures per each, as well as maybe $5-10K of molds.
There is no where near the demand for LT1 intakes compared to LS engines by a factor of hundreds. That's why we don't see them. Hey, it's a great idea, but when they cost over $1000, you'll be lucky to sell a dozen.
Hey, maybe you are made of money and don't mind losing a ton of it. If that is the case, go for it, and offer the manifolds at the street price of a FAST. You'll lose a lot on each sale...but you can make it up in volume.

Awsome to have new LT1 concepts/parts still coming out. I hope it doesn't become some monster intake that only people turning 6500+ will really enjoy. I think it would be cool if it were to become a standard initial bolt on like CAI, headers, catback... I'm not very knowledgable about the shortcomings of the stock LTx intake but...
- Plenum volume
- changing/altering fuel rail crossover somehow
- composite instead of aluminum
- extra material around the runners for future porting
- keeping the cost at $500 or less
- able to accept the variety of throttle bodies out there (monoblad, 48-58mm)
All sound like good ideas to me.
