yes, that should be correct, the 2:1 ratio (36:18) for the 2 gears, as
the cam runs at 1/2 crank speed.
The timing chain can still be the same, even if the gears are different
diameters for the 2 cars - just would mean that the cam and crank are
spaced differently.
So, anyone with cam gear handy to count teeth?
