Jeff, I'm going to respond here just so nobody thinks I've been sitting around
I've been working on getting the crossram intake ready for dyno testing, but I keep getting stopped for various reasons, not the least of which is getting the cylinder head package into production. Currently I'm waiting for a throttle position sensor so I can run the crossram setup; I couldn't make the TPS sensor that I had work. Once I get that intake tested it's back to the RE heads, where I'll be testing all the intakes again, with the updated cam. I love testing intakes
I've also been working on the design of a few other intakes, to try to improve the performance of the 8V intake, and also to make a lower 4V intake. I'd really like to be able to run the cylinder head package on my Mach 1 with the shaker hood scoop, but the current "Tall and Terrible" Rasputin intake (Royce B's words, not mine) just would never fit under the shaker. So I'm working on a lower 4V intake that might work.
My rationale on this is that with a little time, and some plastic, I can 3D print plastic versions of these manifolds and test them. I tried to do this once before, but I did it with a multi-piece intake, and when I bolted it down it wouldn't hold together. Lesson learned, the ones I'm working on now are printed as a single piece. Here's some pictures of the first one, which just came off the printer today. It is more like a traditional sheet metal or billet intake. I plan to use the aluminum top shown in the pictures, but that is set up for 4150 carbs, so I may 3D print a top just for the Dominators so I have an apples to apples comparison with the testing already completed. I also have another version of this manifold with significantly shorter runners, that may prove to be better at the higher engine speeds. When that one is finished I'll print the lower version of the 4V intake. These should all be very interesting tests, and help me zero in on the best intake designs for production.
