I installed the FBO complete system with Don's distributor tailored for my 64 Belvedere's stock 330 horse 383. The ignition system works great & rev limiter is a nice feature. I hid the box & his voltage reg & distributor looks stock. Only issue I've had is trying to get the dizzy timing right to stop detonation under load & I think its a carb/vacuum issue. Don's customer service is great & so is the system's quality.
If you're using your own dizzy, check his site to make sure its compatible with his system.

Thanks Charger727 and Triggerfish for the feedback. I've been running an MSD 6AL, but it feels kind of cluttered under the hood of my 70 Dart and I've spliced into the original loom so many times I can't remember whats what anymore. Thinking of going to the FBO and replacing the underhood loom to sort of start over and clean things up. I'm running a stock MP stock replacement electronic ignition distributor, but I'll double check the website.

The FBO control box uses a board by Daytona Sensors. DS makes very nice stuff. I wouldn't hesitate to use it. The FBO box is an electronic switch and not a capacitive discharge ignition. There is nothing wrong with that, as the inductive ignition gives a long spark compared to a CD unit which substitutes a series of shorter sparks until 3000rpm or so.
Both the FBO box and the Rev-N-nator claim to improve upon the stock Chrysler box. This is probably done by both: (a) turning on and off more quickly, giving coil longer time to charge between sparks, and, (b) being able to switch larger currents.
The gain is by charging the coil better, making a better spark and carrying this higher in the rpm range. The transistors used in the Mopar and aftermarket stock type boxes are relatively slow to switch. The typical can-type coil isn't terribly efficient, meaning that quite a bit of the energy with which it is charged is lost. The E-core coil is a more efficient design and will result in better sparks. My favorite OEM E-core coil was used with Ford's TFI ignition and is on millions of Tauruses, mustangs, etc.
The MSD6 shouldn't require a complicated wiring setup. Big red and black wires to battery, small red wire connected to the input side of the ballast resistor, two wires to the coil and a twisted pair to the electronic ignition output, using a 2-pin trailer connector to mate. It looked a lot better when I took the orange box and associated harness off the firewall.

R. good stuff right here. i read this article about the differences quite awhile ago. pretty interesting http://www.onallcylinders.com/2014/11/07...ctive-ignition/

I've been reading Jeff Smith for years. He's usually pretty close in his descriptions. He botched a couple of major points, though.
1. The coil is an inductor. While the coil is charging, a magnetic field is created. It is the collapse of that magnetic field that forces the power out to the plugs.
2. The CD ignition receives voltage and stores it in a capacitor. When the capacitor discharges into the coil, it sends most of its stored energy. As the resistance of the coil is very low to begin with, the capacitor voltage flashes high, which means it can charge the coil much more quickly than 12 VDC. The resultant circuit is an RLC circuit and I have not done the math. But believe me, some people have.
3. The coil-on-plug or coil-near-plug system was invented by Electromotive in the early '80s. The major auto manufacturers have licensed Electromotive technology to create their own systems. Through the years Electromotive has been the leader in precision ignition systems. The spark their equipment produces is a higher voltage long duration spark. This is better than CD and probably better than a multiple spark.
I nearly bought a second generation Electromotive system back in the mid '90s. But someone had more money than I.

The first line of my first post, "The FBO control box uses a board by Daytona Sensors. DS makes very nice stuff. I wouldn't hesitate to use it." says everything the OP needed to know. In my humble opinion, at least.
The description of the box as induction and not CDI is because some coils work better with inductive and some work better with CDI. With that box I'd use an FD478 replacement Ford TFI coil. I have been pushing since there are some on ebay for less than $10.00.
I agree that the rest of my stuff didn't really make any difference to the OP's question.
Yes, this IS Moparts. At least it was a fresh post and not old enough to vote!

very interesting and we have totally hijacked the OP's thread! ah well, this IS Moparts after all  As the OP I have no objection. The information is interesting, valuable and much appreciated.
