is there any chance of unit construction being implemented in Automation? (no separate cylinder head)
I know this has been mainly used in bikes, but there have been a few instances where it has been used in car engines, most notably in the Offenhauser engines that dominated open wheel racing in the 50s and 60s in America.
While it would probably double or triple the man-hours number for any engine, it does allow for higher compressions and provide better reliability.
