What wears or stretches more on dbl roller timing chains? Top cog? Lower sprocket? I just got a more " economy " timing set and wondering if i should advance the cam a little to compensate for wear ?


Don`t know what these guys are joking about but a few builders I know advance it for that reason to compensate for chain stretch. At Pettis we`d boil the chains in motor oil to impregnate the hot oil into em and lessen the stretching that takes place on a running engine.
