v-12 firing order


Recommended Posts

the  "motor" manual i have shows the firing order to be 1-4-9-8-5-2-11-10-3-6-7-12, if the wires are placed in the cap terminals  as numbered and the rotor rotated it appears the firing order would be 1-4-3-8-5-2-11-10-9-6-7-12, which one is correct ?

I have the 1941 wiring diagram and the 1946 Service manual and both of them show 1-4-9-8-5-2-11-10-3-6-7-12 firing order. I don't have information for the 1942 distributor, but I believe that it is the same.

Tom is right, but it can be confusing.  The engine is 75 degree, odd fire, the right bank is 15 degrees after the left bank.  Both sides are even fire 6 cylinders.  However, the distributor contacts are offset, so each set of points fires three on one side and then three on the other side, so six plug wires must cross the engine.
