Duraspark or Pertronix
So I finally set the timing on my 390 in my '69 f250 camper special ranger. That was a task in itself considering the distributor wouldn't budge. After putting the new vacuum advance on the distributor and resetting the points I took it for a spin. The problem seems to be every time I step on it the points lose their gap. Im somewhat familiar with Duraspark I used to drive a '83 f150 302. That seems to be the question Duraspark or Pertronix. I don't mind doing the work to assemble the Duraspark but would I gain much over Pertronix? The points are goin away. Thanks, Corey.

The advantage with a DS system is parts availability in the event a component goes out. Pertonix is supposed to be bulletproof (other opinions may vary but I've run one since 1990 n my 65 'Stang) but you do have the option of keeping the points/parts in a baggie in the glovebox.
Either way going electronic with a simplified system results in a smoother starts, idle, and ignition timing.

Just wondering, when did you install it? I've wanted to try one, but I've been afraid to as you hear all kinds of horror stories about their stuff....the only thing I've ever used of theirs' is the set of solid flat tappet lifters in my cleveland, and that's only because I really trust the individual who suggested them to me.

Ditch the points! I got my HEI dizzy off of eBay for around $139 WITH already cut to length 8mm wires. Just pull out your old dizzy, slid the HEI in and find a switchable 12V source. Regap plugs to .045, then put on your new wires. Reset timing and your done. Mine is right at a year old now and no problems. Start right up as soon as I turn the key.

You don't need your factory coil.....everything is built into the dizzy under the cap, so you will also end up with a clean look as well. All you have to do is find the wire that supplies 12V as soon as you turn the key on the back of your ignition switch. You then run a wire from that 12V wire you just found to the back of the HEI dizzy cap. Its labeled battery I think???? the other is labeled tach. Simple.
The only downfall is you can't use a factory air cleaner unless you install a 2 inch spacer under the carb because the dizzy cap is a lot bigger than a stock Ford cap. I would install a spacer under the carb on all these trucks anyway....

I've had mine just over a year too . $140 off ebay with wires
for the 12v i removed my instrument cluster and found the PINK resistor wire .
i found were it ended and went to a regular wire . i tapped in the other ignition controlled wire ( red /green i think) ran a wire from there to were pink ends . 12v to coil.
