I saw this thing at my buddy’s place, and I haven’t been able to find much information about it.  It’s a shovelhead – or pan I guess – case with cast cylinders… as you can see, the cases split top to bottom, which means the flywheel assembly would have to be build, along with pistons, and the whole thing fished up from the bottom.  It actually belonged to a former employee of mine, a fairly decent mechanic, and he was never able to get the assembly installed.  Anyhoo, any information you’ve got on it would be kick ass.
