if you are running the stock fuel injection you can't adjust the timing by rotating the distributor. The timing is set by the on board computer. I may be wrong bout this but that's according to my Haynes manual.

If you have an older system with 9:1 compression or less then you can set initial timing for maybe 6 or 7 degrees advanced and it shouldn't detonate.

There is no adjusting the timing on the magnum engines. Like said above, it is all controlled by the computer and rotating the distributor does nothing.

The only thing you want to do with the distributer is make sure the engine is TDC on #1 and the rotor is directly pointing to the #1 cly plug wire. And make sure all the plug wires are in the correct place for the firring order. If you need the firing order or the Cly positions look at the intake manifold it is casted on it.

Alrighty, thanks.

SYMPTOM/CONDITION:
Vehicles may exhibit surging, light bucking, or intermittent engine misfiring. This will most likely occur when the vehicle is at operating temperature, and under a light load at approximately 2000 RPM. This condition may be caused by a mis-indexed distributor. The following procedure is an alternative to the indexing procedure outlined in the service manual.
REPAIR PROCEDURE:
This bulletin outlines an alternative distributor indexing procedure.
1.
Connect a voltmeter to the distributor sensor connector by removing the end seal and carefully back probing the connector. Connect the positive lead to the sensor output pin (pin 3, either a tan wire with a yellow tracer or a gray wire, depending on vehicle application). Connect the negative lead to the sensor ground pin (pin 2, a black wire with a light blue tracer).
2.
Rotate the engine clockwise as viewed from the front, until the number one piston is at Top Dead Center (TDC) of the compression stroke. The timing mark on the vibration damper should line up with the zero degree (TDC) mark on the timing chain case cover.
3.
Continue to rotate the engine slowly clockwise until the V6 or V8 mark (depending on engine type) lines up with the zero degree (TDC) mark on the timing chain case cover. The V8 mark is 17.5°after TDC and the V6 mark is 147°after TDC.

NOTE:
DO NOT ROTATE THE ENGINE COUNTER CLOCKWISE. IF THE ENGINE IS ROTATED BEYOND THE MARK, RETURN TO STEP 2 AND REPEAT THE PROCEDURE.
4.
Loosen the distributor clamp bolt.
5.
With the ignition switch in the ON position, rotate the distributor slightly in either direction until the voltmeter switches between the sensor transition point of 0 and 5 volts.
6.
Adjust the distributor as close as possible to either side of this transition point and tighten the distributor clamp bolt to 170-230 in.lbs. (19-26 N-m).

POLICY:
Reimbursable within the provisions of the warranty.

Good trick is get an old cap and snap off the #1 cyl nipple. set engine on #1TDC and look at the cap to see if its in the #1 position on the distributor.
