Timing is set using a scan tool and watching the cam offset in the parameters. The crank sensor is fixed-that sets timing and the distributor is only a distribution point and a place for the cam sensor. When the crank marks lines up,the rotor points to the arrow on the distributor base.Not to burn up the contacts in the cap,the cam off set is then set to within 2 degress of zero with a scanner.
