I have talked with Mike (KLZE Porsche) a lot about this build and he has helped me a lot with some of the detail stuff. I actually just spoke with him last night about the ITB setup. His application is very different from mine.
I am wanting to keep this under the hood without the huge bulge in the hood. He figures in his he is going to have to do something pretty wild with his hood. He is also doing his for a F.I. setup and using a different transmission (where he has to move the motor and such around anyways). Doing the cross ram would be nice, but one..its very complicated, two I do not have room under the hood for something like that. The issue is the height at the front head deck..the stock manifold slopes back away from the hood and is only marginally taller that the valve cover..so I run out of room quickly.
I like the putty/clay idea though..might have to give that a shot!
Why don't you start a build thread and take some photos

we'd all love to see this thing "in the build".
