Separate issue: I started this thread, and asked for expressions of interest in this engine. I believe we have our answer: almost NONE when you come right down to it.
While we may love the concept, the vast majority of Stovebolters evidently do not share our enthusiasm.
I know when to quit. I'm buying an LS series V8, and wait until you hear what IT can do with very little money, and a carburetor versus EFI setup.
