Post Ford 300 distributors
http://m.summitracing.com/parts/DUI-39820BK

Are these good distributors? Anyone have any pros and cons for these distributors? What happens if the coil or electronic ignition components fail? Can you buy replacement parts, or do you have to buy a whole new distributor? Is anyone running just regular stock distributors with electronic conversion kits? How reliable are they? Any suggestions are appreciated..thanks guys

It's basically a GM HEI distributor that's been adapted to fit a Ford 300 repair parts are easy to find at most any parts house. You can buy the same (DUI) from this sites sponsor for a better price (below Link).

Many are running stock points distributors and with a Pertronix's electronic or a MSD box and a few other ways it can be done too. Even more use the Dura Spark I or II distributor swap they will all work I like to use a DSII :nod:

Another vote for DSII. I use 4 prong GM module with mine, but the Ford module designed for them is fine. The GM module though lets you use either GM HEI coil or Ford TFI coil. Thats its big advantage. Also easy to wire.

But if you want a point distributor, be aware there are some from 60s with only vacuum advance on them. These require a carburetor with special vacuum port designed to work with them. I think only the 240 had this from factory, but since its same engine family it maybe sold on ebay as fitting 300 or listed in parts catalog as fitting. Just friendly heads up so you dont buy something you cant use. Ford had used this sytem in 40s and 50s on their sixes to save couple bucks I guess and it continued up into mid 60s.

Also just to give you another option a point distributor can be used with HEI/TFI coil by using a TFI ignition module from 80s/early90s Ford. The points then just trigger the TFI module and it fires the coil. Points last much longer just used as trigger, current through them is much less.

I use that distributor on my engine, and have nothing bad to say about it. :thumbup:

only "issue" i had was a simple one, i had to rock the truck in gear (standard) to get it to drop into the oil pump.

Oh and my harmonic balancer was spun i needed a new one but that's not the distributors fault :lol:

When y'all refer to the duraspark II, is that an actual distributor, or just the components to swap out of another distributor? I saw on that classicinlines site that they had a duraspark II distributor for the smaller sixes but not for the 300s...what's a good stock distributor to purchase to install the duraspark into?

Post Re: Ford 300 distributors
Dura Spark I and II (will say it on the control box) is Fords name for their electronic ignition system they made to replace the old point distributors. Starting in about late 1974 to 83 the system is the complete distributor with improved cap and rotor, a control box, wire harness, and coil. If you can find all the org. stock parts with the wire harness it's a very quick and easy bolt on swap. Only needs to have one new wire run to replace or bypass the resistor wire from ignition switch.

I vot for the DSII with or without the GM module and TFI coil.
Either type of DSII will be more ignition than 99% of the 300s out there needs.

AND
$369. and some change?? :shock: :shock: thats about $320 more than what I'd be willing to pay.

Few place to look is a local wrecking yard should have some is a stock part, and or any auto parts store. You could also post your needs in the Sale / Wanted section

I've bought DSII's off ebay, Rock Auto, and any on-line chain store site. Many of them are "Card-One" rebuilts.

The DS2's were sold between about '75 and mid 80's. I usually get about a 1980 unit. Oh, and you might as well get the complete dizzy with base, cap, and rotor. About $50-$60 over the counter. No point in messing with a used, no warranty unit, at these prices. You will need to enter in a vehicle with a 300 engine (truck or van, usually). Make sure you get a single vacuum canister unit.

i think you spelled that wrong, its "car-DONE", cause once you start buying cardone parts, your car is about done for

+1 on a duraspark from a 1980ish truck. they're dead reliable, and provide enough power. in a v6 car i used to have, i did the HEI upgrade (module and coil) and that added a few HP according to my butt-dyno.
on my flatbed, i have a points dizzy triggering a TFI module, and that helped it out a bit.

for all of them, wiring is very simple.

:beer: Hi Element7878.I have used the DS11 ignition system since appx 1994.The first was a FREBE from a friend when he heard that I wanted an eletronic ign.It came out of an 80`s something Lincoln with a 302.It went into my 74 F100 with a 302.I now have an 84 F150 with the 300 I6 with another FREEBE DS11 system.I removed the TFI/electronic controlled carb and computer system.Best upgrade that I think that I have ever made.Both DS11systems were used,and I have never had an ign brain failure.
One thing that will help the security of the system against failure is a little hint that I learned here at Fordsix,is to run an extra ground from one of the brain box mounting screws to the firewall.
Good luck.Have fun.Be safe.
