It would be easy to make long head bolts and then add a bracket to pick up the frame, the 8mm bolts would work the best. Have fun, Dave. bld.
The only problem I can see with a cylinder head mount is the variety of frame geometries. I think it would be hard to make a one-size fits all kit without half of them looking cobbled together. I'm certainly open to suggestions. Once the CNC is set-up for low cost volume production the product must have mass appeal.
The front mount, rear mount, set-up works great provided you have a good set of mounts. The mounts shown in this thread worked exactly as intended. They are too big, and will be streamlined about 50% in the CNC. other than that they offered total isolation. It's really best for the engine to have a little give anyway. When mounted rigid, the engine transmits a high harmonic through the frame and itself...not good...foaming fuel, broken hardware, exhaust pipes that shake loose etc. I know race cars use solid mounts. These engines are also well balanced. This isn't a race car, and it is hardly balanced.
