Gose counterclockwise on 302-360-390 and 460.
Rtr. turning clockwise. Rotate distributor counter clockwise to advance timing, clockwise to retard.
Counter clockwise to advance.......clockwise to retard
Loosen the distributor, bring the #1 piston to Top Dead Center (TDC), connect the timing light, and rotate the distributor clockwise or counterclockwise to advance or retard the timing until the timing light indicates that it's set properly.
counter clockwise
counter clockwise
Turn it to the left which will be counterclockwise.
Yes it does. Clockwise retards it. Counter clockwise advances it.
To advance ignition timing, loosen the distributor clamp and in very small increments turn the distributor body in the OPPOSITE direction of the rotor's normal rotation. If you don't know which way the rotor turns, you can find out easily by removing the distributor cap and having a helper turn the engine over with the ignition key switch. To advance the timing turn the distributor counter clockwise.
Loosen the bolt holding the distributor in place, and turn the distributor counter clockwise. If it bucks the starter, it is too far advanced.
The way the rotor rotates retards. If the distributor turns clockwise, then turning the distributor clockwise retards the timing.
Loosen the distributor hold-down bolt. Standing in front of the vehicle looking at the engine turning the distributor clockwise advances the timing. Turning the distributor counter-clockwise is retarding the timing. Hold the distributor steady while tightening the hold-down bolt. Factory hold-down bolt needs a 1/2 inch wrench.
