Dirt cheap Ignition

If I'm reading that right, doesn't that eliminate the ballast resistor and the big ford ignition module?

Is this a good way to go?

If it is a good way to go, I could possibly be able to take back a $30+ ignition module and a $17 ballast resistor to advance auto lol

 

What engine are we asking about? I certainly don't remember where an ignition module came on the vintage engines that were stock in this vintage trucks. There are add in electronic ignitions that take place of the points in this vintage truck.

 

I used the Dura Spark II on my 71 302, I used the ignition module & ballast resistor; as mentioned above it gets rid of the points. You will also need another distributor. Also the second sentence in the article you reference states "This requires pulling out the TFI distributor and coil and replacing them with the Duraspark distributor, coil, module, starter solenoid, and ballast resistor". There is a better article for doing this conversion on this site, you should be able to conduct a search for dura spark II ignition conversion.

 

He's asking if this would work in his 302.

 

Yeah its for my my 302. I have a 85 mustang distributor with a steel gear for the roller cam plus the rest of the stuff for the Duraspark II. I was looking at this website and saw that using the chevy HEI module would eliminate having to use the ford module and ballast resistor and thought that was a neat idea. I was wandering if anyone has had experience with doing this OR thought it was a good idea.

 

Look up Davis Unified Ignition. or D.U.I. AFAIK, this is what they do, and sell it as a unit.

Personally, I like the duraspark II the best. I even removed the TFI from my 300 6, and replaced it with a DSII, and the only cost was dist., and a pigtail to join the tfi coil to the DSII red and green wires.

 

Ooops! my bad...I didn'tsee the Duraspark II with HEI module part.

 

The problem I've seen with the HEI module with the DSII distributor is they are quite prone to failure. They need to mounted on some kind of heat sink or they fail a lot quicker.

Personally my feelings are to just run the stock DSII stuff or go with an aftermarket box ( LIke Mallory, MSD, etc. ) .

If you are looking for something else besides the DSII. I've seen somewhere that some guys were running the old Chrysler ignition modules.

 

I've read pros and cons on the HEI module setup. I upgraded my 68 302 points to a later DSII & mounted the module on the inner fender in front of the radiator for better cooling. Seems that heat contributes to TFI and DSII module failures. I also have an HEI module & computer heat sink that I'm tinkering with & plan to install it in a similar location on the passenger fender as a redundant system in case the DSII module dies. My first thought was to just mount a second DSII module next to the current one so I would only need to swap connectors if the main one failed -- but that would be too easy (& sensible). I think the DSII module retards timing by 2 degrees during cranking (if wired correctly) to aid starting. The HEI system wouldn't do that, but I'm not running so much initial timing that it should make a difference. I had an 84 Mustang GT Turbo with a habit of eating TFI modules. I fixed the problem by relocating the module from the distributor to a heat sink on the fender (but still carried a spare in the glove box). That's why I'm so paranoid...
