I started on a 292 project which I was planning to turbocharge. I've bought a MegaSquirt for same, and was planning to use multiport fuel injection. Because I haven't found any intakes that meet my needs, I've pretty much resigned myself to fabricating my own intake.

My question is as follows: I've always wondered about constructing the siamese intake port with a full length splitter so that it becomes two individual ports on the manifold side. The port splitter would protrude from the intake, and be shaped to form with the head bolt boss and so provide a properly tapered and smoothed passage at least all the way past the boss.

Even though a 'window' to the other side of the inner port would exist, it seems like a satisfactory enough passage to create some ram effect would result. Has this been tried?
