Looks like a basket case and here is why


With a dual overhead setup like that the last gear to be driven will wear with uncontrollable wear causing a timing issue with the valves. the sealing which they have cleverly done on the sides using a electron discharge machining center
(or cnc grinder)will cause massive coking of the exhaust and teh rotating valve will become fill of black carbon. The unit bearings are open and are also a innefficient design that will lead to short bearing life. Not too many engines use ball bearings. It also looks like a solid piece but with a solid piece comes thermal expansion warpage and cracks from small pressure differences in the metals...

I give it 3 out of 10 for ingenuity :sa:

the system might work but not in a jeep. still looks neat!
