duraspark or pertronix. it is going on a 69 390 in an f-250.

 

To replace the points I went with Crane XR-i FireBall PS20 and I highly recommend it!! if that is what you are asking

I forgot to add the link of where i got it

IMO, Pertronix .. two-wire hookup. EZ. But if a module goes bad then ya gotta pull the points out of the glove box and reinstall them ..or get towed. All my formerly point-equipped vehicles have Pertronix and have never had one go bad.. the oldest being from 1991.


Duraspark... extra wiring, specific dizzy, replacement modules can be had via a local parts store but a genuine Motorcraft module is preferred.

 

"Better" is a subjective term that has particular meaning to the particular individual and not everybody has the same exact idea as to what "better" is. One man's better is another man's bad.

If you run a Pertronix unit, spring for an additional module and keep it in your glove box. Replacement (if needed) will be direct and you won't have to drag out a points setup to limp you home before you replace the module with another Pertronix unit.

Other than the wiring harness between the ignition module and the distributor (which are just connectors that snap together), the Ford Duraspark II is also a two wire hookup to the vehicles wiring --white wire goes to a switched 12 volts in start (automatically retards the timing to be easier on the starter when cranking) and the red wire goes to a switched 12 volts in run. That's it.

The Duraspark II distributor cap has spark plug type terminals to positively engage the plug wires, as opposed to the older push-in type plug wire terminal distributor cap. DS-II distributor cap also has widely spaced terminals. If you're going with a higher output ignition and a fatter sparkplug gap, having the cap terminals spaced further apart reduces the chances of crossfiring and engine missing compared to the regular, smaller diameter distributor cap.

There are also numerous aftermarket ignition systems that offer various components to go to higher power electronic ignitions. It would probably be best to research the various ignitions systems (stock and aftermarket). From there, you can decide which system you think will be the best for your needs.

 

... or check underneath the dizzy cap of every points-equipped Dent and Bump at the salvage yard and be lucky to find your spare Pertronix module.

 

That's where I found mine,it cost me $7.00.

 

Yea, I found 8 over the yrs and sold 5 on the ebay an just have 3 to a guy who has a 62 f100 with 66 T-bird 390 in it that was running crappy. So when he installed one of the Pertronix units he found the dizzy ground wire broken fix it while doing the Pertronix install. Now runs smoother starts easier he say.

When doing the Pick N Pull walk through, I just look for 2 wires coming out of the dizzy. A red & black wire and , I know it has a Pertronix unit then check with an ohm meter to see if any good.

And as Ultraranger says CYA
One learns to cover is Azz at all time by having a spare dizzy part too a spare tire will always get to home on your own.

I have a Pertronix, MSD blaster coil, Accel Cap and rotor, Autolite AR32 spark plugs and Accel 8MM wires.
This 428 (465) pulls strong to 5500 without a hitch.

The colder plugs allowed me to add about 2 degrees timing which made the FE more responsive.

That is a great idea!

 

I have an electronic ignition called Hot spark. Works the same as Pertronics. Hotspark was recommended by an older gentleman on Fordification. It was cheaper than Pertronics. Easy to install. Has worked great for the 3 years I've had it.

 

I've had a few different set ups, Petronix was trouble free and easy to install. But my favorite ignition is where I use the Duraspark ll distributor with a GM module and the high energy coil from about 1990 pickup. But then I like cheap stuff and junkyard engineering, kinda old school way instead of trotting out the credit card for the latest.
The advantage to the gm module is that it varys the dwell with rpm and can handle the big coil. The blue grommet can't always take the heat from the hot coil

 

If any of you have a dead Duraspark box, how about using a GM HEI module in its place?

Yeah, plenty easy to do. Make sure it's on a good heatsink with the dielectric grease. I modified the remote (think early 90s V8 pickup) TFI heatsinks but have even know guys to use a modified briggs and stratton head to make one. GM module will die quick from heat if you don't mount it right.

 

i know this is a bit late but just found it and it sounds neat,along with the 3g alternator upgrade.

 

Found what?
