Dura Spark II Upgrade For FE Series Engine

This is a very simple conversion to install the Dura Spark II system, using a “Breakerless” Dura Spark I) FE distributor from a 360/390CID Ford truck on an earlier engine.

1. Reliability. The terminals are farther apart in the large cap
and this helps prevent cross fire in the cap. The larger wires
also conduct better.
2. Performance. The larger separation in the cap will allow the
use of more powerful coils without cross fire.
3. Appearance. The conversion is clean.
You will need to pick up 6 parts:

You will need to pick up 6 parts:

1. Spacer. This is the
adapter that allows the large
cap to be used. The large
cap is actually flat and snaps
onto the spacer. This can be
had at a wrecking yard
cheap.

2. Cap and Rotor
3. 8.5mm Spark Plug Wires
4. Coil from Dura Spark II vehicle
5. Dura Spark II Module
6. Complete wire harness, do not cut harness

You will notice that all parts can be had at a wrecking yard if they
are in good shape. This may not be too far fetched because some
people will give a dying car a tune up to try to keep it running and
when it does die the new parts go to the wrecking yard on the car.
There are tune up kits that include the cap, rotor and wires but
normally the spacer is not included so that is the only one you
should get at the wrecking yard.

1. Note spark plug firing order and write it down! FE Series Firing Order is: 1*5*4*2*6*3*7*8

2. Remove the old distributor cap and rotor.

3. Install the new spacer. There is a rubber plug in the base of the distributor that will cause a little interference. The spacer has a square tab that fits in the cut out that the rubber plug is in. The plug can be compressed by the spacer so it will fit or you could trim the plug. I don't recommend trimming it because you could cut the wires that go to the magnetic pickup.

4. Secure the spacer in place with the snap springs that held the old distributor cap.

5. Install the new rotor.

6. Install the new cap.

7. Install the 8.5mm spark plug wires.

8. Install complete wire harness

9. Mount module to inner fender

10. Step back and enjoy your handy work.
