dura spark dizzy
Hey Gents,
I've been searching the classifieds for a mid 70's dura spark dizzy fitting a 390, no luck. Does anyone know of one available, I'm dropping the points and the worthless pertronix units, had two of them leave me switching back to points on the road in the last 3 yrs. just tired of them I don't think they were ment for everyday drivers.
Thanks for any help

If you don't like Petronix, you won't like DuraSpark...either.There were sooo many problems with DuraSpark ignition modules in the 1970's, that Ford techs referred to it as NeverSpark!
1974/76 F100/350 360/390 use the same DuraSpark dizzy, but even though DuraSpark was introduced in 1974, not all 1974/75 FoMoCo vehicles came with it.
DuraSpark ignition modules and stator:
1974/79: The size of the engine makes no difference, the same modules were used with I-4, I-6, V6 & V8 engines, in everything: Passenger Cars, Trucks, Bronco's and Econolines.
The module used in 1974 is one year only / The module used in 1975 is one year only.
1976/79: There were three modules, two were only used in some sold new in CA vehicles.
Above where the wires feed out is a colored plastic square. The following is what you want:
1U2Z-12A199-AA (replaced D9VZ-12A199-A, D8VZ-12A199-A, D6AZ-12A199-A) .. Ignition Module - BLUE plastic square (Motorcraft DY-893).
Applications: Millions of 1976/96 FoMoCo vehicles (excepting some sold new in CA vehicles).
D4PZ-12A112-A .. Stator aka Magnetic Pickup Coil (Motorcraft DU-1A).
Applications: ALL 1974/79 V8 engines, except 1979 LTD/Grand Marquis 351W w/EEC.

They were installed correctly my friend! one went south when the coil died, would start cold but not fire on a hot start. plugged in a new unit and it fired right away and lasted 2 years. Then it to would fail only on hot starts, let it set dead cold and it will fire...did all the voltage checks and amps, resistance ect. even put on another coil, on a hot start, like when getting gas, it would fail till cold....and nothing wrong with the truck! As for not liking the dura spark or dura II, I only had one go bad it would kick back on some damp starts, which is the start circuit failing and only when you turn off the key when it would not fire while turning over. Had them in amc cars and fords with no problems till my 83 van.

Any parts store has rebuilt units for you! Just ask for one for a 1975 or 1976 truck. Should be under 50.00! Then just give them yours as a core (wait a few days they will not know the difference between a duraspark dizzy and points)

Hey Cracker,
I did just that! cked the pros and cons of dura vs the hei conversion and went with the hei on ebay. GM has had that going for a long time and with good success.
I see you have mustang projects, some time I'll have to shoot you a line on what I did with a mustang II 2.8 v6. Thanks ALL for the help, it's good to be able to pick up ideas on a great forum.

Keep us posted on the HEI unit! There was a discussion on this topic about a month or so ago. Looking at info on the unit it came to our attention that the HEI units are made in China and are problem ****. The OP ended up going with a duraspark and is very happy with it. Most guys go with an MSD module.

Yup says right on the carton made in china. I still put it in and so far (30miles on it) things are going fine. I looked on line and the problems seemed to be with Jeeps and billit cams wearing out the cam gears. We have steel cams, I did ck the gear fit for over size dizzy gear, had up and down movement on the rotor so the gears seem to be fitting ok. I haven't regapped the plugs to .045 yet but with .030 it fired with out setting the choke this is a good thing, never fired like that before. I hope it continues along this line and no problems pop up.
