Cylinder Head
Camshaft
The camshaft is a cast piece. By improving dimensional accuracy, it became possible to achieve minimum space be-
tween cams, thus allowing a more compact cylinder head. Each camshaft is supported on four bearing journals with forc-
ed lubrication. On the right end of each camshaft is a driven pulley. The exhaust and intake cycles require a total of 36
cam lobes to open and close the valves.
