Best Electronic Ignition upgrade
I know the Pertronix (sp) is a popular, easy, cheap upgrade. And I'm not ruling that option out. But I was wondering if there was a better option, even if more expensive or a little more work. I'm not cutting any corners on this truck as I intend to drive it forever and want it to perform as such. Any thoughts appreciated.
Truck Specs: 1967 Ford F100 Ranger, SWB, 390, mild cam, 4bl carb, aluminum intake, 428 scj heads, headers, backed by a C6 with shift kit.

Look into Crane's XR 3000 inductive ignition system with their LX 91 coil.
This system allows full 12 volts to the coil so your not limited by a ballast or the original resistor ignition wire. One step lower is Crane's XR 700 but requires a ballast. XR 700 was made by Allison, been running one over 20 happy years. Many others on this forum besides myself have had MSD's with failures.

I prefer the Ford Duraspark II system, myself. Easy to obtain and harvest from a donor truck, easy to install in a points truck but make it look factory, reliable, and easy to repair with Ford parts.

That's the words "easy to repair" that I want to avoid all together hence Crane's optical trigger system. Stock dizzy with the control box mounted on inner fender liner. I go for function not 100 point show, if then a Crane XRI install.

I had the Pertronixs Ignitor system and had no problems with it. However I felt like I needed a rev limiter on the truck and switched to the Crane XRi ign. system. Now that I have 2k+ miles on the Crane XRi system I prefer it over the Pertronixs. I have been listening to Beemer Nut tell how good his Crane system has been for him for over a year and his opinion and recommendation influenced my decision as much as Crane's good name for fine, trouble free products. jmo, Charles

I really like the DUI system. It's a GM HEI distributor, 1 wire hookup, and custom curved to your specs. It runs a full 12v, puts out up to 60,000v, and I ran mine with a .060" gap.
I tried DSII on that engine, it wouldn't reliably light off the mix at the compression I was running, even setup to run 12v through a later style e-coil.
Parts are cheap, and at every parts store.

charles jones; with the XRI as well XR 700 Crane ignition your coil current is limited by having to run a ballast resistor or Ford's resistor ignition wire plus the higher resistance can type coils. The XR 3000 run straight 12 volts without a ballast or Ford's resistor wire for to the coil for a higher current system plus the more efficient E-coil with a lower primary resistance. Higher current means hotter spark. As I said many times in the past, buy the best once, granted XRI is a improvement over points.
XRI yields a spark duration of 2,100 microseconds, XR 3000 of 2,800 microseconds. All three above inductive are a lot longer in spark duration vs a CD system which is what you want on a street motor.

The Ford system on the 75 and 76 360/390s works fine and is easy and cheap to install, you only need a few small wiring mods and it looks almost stock!
I used it on our 68 Mercury with a 360 and it has worked fine for 4 yrs now with no problems except for replacement of the original coil. (oops) I even used the heads of the 76 390.

I'm not too much concerned about looking factory or stock. No plans on an original restoration truck. I just want the best performance, reliablity and quality I can get.
Any ideas on coil, plug wires and even distributor cap to go with?
Thanks for all the info.

Looking for "the best" or a practical ignition system?
Without going overboard with a race only system that will cause high plug erosion on a street motor, no ballast or resistor wire to limit primary current which results in higher secondary current. Within a reason on price and quality a Crane XR 3000 system with a LX 91 "E-coil". I have seen a XR 3000 work without any problems on a Vortech boosted FE at 6 psi.

I am also running the crane XR1 system and am very pleased, I am also running a flamethrower 2 coil with no external resistor. Main reason I went with the XR1 was because it has the built in rev limiter.
