- I do believe the gears are already hardened. You could try the freeze method which is supposed to make parts last longer. Mike /// datsun-roadsters@autox.team.net mailing list

- 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 car
