You know, I wonder how well one of these would fit in the "Norley" Featherbed-style frames made for Sportster engines.... Hmmmm.
Not sure.But the Vincent engine fit in the regular featherbed frame, with some special engine mounts added. Maybe this one might too.The issue that I see is that this Musket has a wet sump with a prominent sump protrusion downward and toward the timing side. That isn't likely to fit down thru the frame cradle, and so that might cause the whole engine to need to sit higher. That could cause an issue with the fit.
