Of course, the
Ford Essex 3 litre V6 in my Scimitar solves the problem
by having no belts or chains at all - just two big gears. The large
gear uses fibre teeth which wear after a few hundred thousand miles, but
that's another story....
That seems like a sensible way of doing it. I take it the Essex is quite
a flat vee design? (just thinking about the Stag engine which is 90
degrees and there's a hell of a distance between crank and cams)
It's 60 degree IIRC. The camshaft sits in the middle of the cylinder
banks at the top, with pushrods running up between the inlet ports.
