ITB's for LS engines

Initially, I will literally be riding the coat tails of the LS platform to get my feet wet. From there I would like to make them work with endless other options. My roots will stay with GM.
I have the manufacturing facility and the initial run would only be to incorporate investment cast base plates to keep the cost down on making the port shapes so we don't have to CNC machine every port. The only one that should require the costly and time consuming machining will be the prototype.
With these, I would like to use them as a tool to create exotic and high end automotive performance parts that perform with the best at a price that the average Joe can afford.

Here's a neet idea, a shared plenum built into the botton of a ITB setup so you will have a nice vaccum reference for brakes and MAP sensor...

I want there to be a simple base plate design with adjustable throttle linkage to bridge the gap between heads. Doing this will allow me to be able to accept as many engine platforms as possible.

Progress Note:
I NEED cylinder heads and even possibly a busted block to mock up with and get measurements from.
I am about to make a trip to Jamison's Corvettes but I highly doubt Mr. Jamison will let me have even a busted engine for free.
The cheaper my design costs are now, the cheaper the parts are later.

The one thing that kind of stuck out to me was the throttle body size. I was looking into building a set a while ago and and found that the 48 / tapered GSXR throttle bodies I was going to use would prove to be too small by other's math. Harrop offers a minimum of 52 with the option of 55. Someone should be willing to give you a set of messed up heads for the price of shipping.

I can pay for any shipping. Just get my phone number and go to a UPS Store and I will pay all shipping costs.
The design I have is set up for a vertical setup. The diameters will be VERY easy to change and adjust on my end and I can make a 6 foot long trumpet if you wanted it
Once people see how easy this design is, there will be people out there going "Why didn't I think of that!". The largest difference is the fact that I am a manager of a machine shop and I know how to use the machinery to put my ideas into fruition. It also helps when the owner of said machine shop is family and is also on board with getting these done. He is in fact making me take time every week in dedication to getting these made. It is always nice when you have someone there to help push you along.

"I was looking into building a set a while ago and and found that the 48 / tapered GSXR throttle bodies I was going to use would prove to be too small by other's math."
A 48mm Weber for example is actually less than that when you count for the venturi and the throttle blade and shaft. So I can see where they say to use a 52mm.

I can't wait to see pics of this setup. Most of the affordable manifolds available to the LS market are still holding us back. We need to let these engine breath in order for them to shine. This product might just be the key if priced right.

Interesting thought. So do you think an ITB would be maybe the best solution with of course the proper diameter and length?

that looks like an ls7 unit.
kinsler does not make any units that work drive by wire, so all newer gen guys are sort of screwed.
there ls1 ls2 cathdral port unit costs about 4900 with a ability to setup the dbw motor.
according to a fellow at kinsler.
the actual unit costs about 2800-2900 but its all the options that you have to purchase that adds up.
ie : $510 for billet fuel rails LOL.
jenvey sells a unit that apparently is out the door at 3500 with shipping.
they were also gonna give me a 10 percent discount on the unit, but i dont have cable throttle, dbw ls2 gto here.
apparently they are working on a dbw unit.
so i will wait for them.
and harrop?
who the hell knows, ive sent a few emails to them with no luck,
i have contacted va speed with no luck also.
probably should call them
but i guess if harrop makes the most complete kit, and supposedly the only dbw kit they will probably charge alot more then id be willing to spend.
