Well, the patent search is turning up little information. At least on the US side. I don't klnow where to check out Japanese patents. So far the automotive stuffI have seen from Yamaha is pretty neat. They even have a patent on an intake system where the runners slide in and out to make them longer and shorter. Like a slide whistle. I will continue to look though.

In other news, the freeze plug finding is going to make things much easier. It should be easily undone if it doesn't work.
Anybody with their intake already off that wants to mess with this? I might mess with it next week sometime. From what I am seeing and guessing on the SHO, LS, and Jag engines, there just needs to be a passage between the banks. Nothing special on the hole or passage diameter.
