Hi George,
what are the pros and cons of EDIS vs Coil near plug ignition for the 351c ?

What is the most straight forward way to make up a coil near plug ignition for Clevelands ?
I hear the GM LS2 truck coils are highly regarded. What simple electronics can be utilized to drive the individual coils without resorting to the use of the GM engine management system ?

I've been keeping my eye on this piece, haven't researched much into what control box to use with it, I'm hoping it might work with the stock ECU from something like a late model Crown Vic. all it needs is a Cleveland dizzy gear swap & to be spliced in as the Crank & Cam Position sensors. just not sure if Ford used 24-1 ?

AEM also had a couple different styles of coils

but I like the idea of using something I can find anywhere, here's a pic of somebody's handy work with Ford COP's

That AEM electronics web site has some interesting items.
It's possible to combine EDIS and an individual coil set-up. In fact, my first EFI installation used an EDIS-8 module from a Crown Vic with 8 Ford COP coils, wired in a waste spark configuration, mounted on the valve covers. I simply replaced the OEM coil boots with some short plug wires.
For a trigger wheel, I bought an entire 5.0 Mustang damper assembly on eBay for $20, removed the trigger wheel and mounted it on my 351C damper, between the damper and the pulley. I used a crank sensor from a Taurus.
I used an Accel DFI GEN 7 ECU to control it all because Accel has EDIS control software. I also used an Accel unit ( http://www.autotrendefi.com/distributor_cap.html ) for the cam sync signal but have a Price Motorsport unit ready to install shortly. The Price unit uses an OEM Ford sensor.
About the AEM sensor you mentioned, I've heard it's notoriously unreliable.

The Ford coils are a bit smaller than the GM coils, I think that helps make a better looking installation.
I would be curious to know how you configured the individual coil wiring to use them in a wasted spark application.
Normal wasted spark coils are configured as in the pic below.

George,
In order to use an EDIS-8 module with 8 individual coils, all you do is "tee" the EDIS-8 module's coil outputs, so they connect to two coils, rather than the intended one side of a four terminal coil pack (if that makes any sense at all!). Specifically, from the EDIS-8 module, connect the first output to the coils on cylinders 1 & 6; the second output to the coils on cylinders 3 & 5, the third to 4 & 7 and the fourth to 2 and 8. You have to run switched power to each coil as well. It's all pretty simple and really just an exercise in harness construction. All of the pigtail connectors are available and I bought mine from Rockauto.com.
I also incorporated an MSD DIS-4 CD unit into my installation, which is designed to be used with a V8 waste spark set-up. I see those on eBay quite frequently for next to nothing.
An EDIS ignition module won't work with any of the GM LS smart coils.
If you have any more questions I'll do my best to answer them for you but because I did this installation about eight years ago, it isn't exactly fresh in my mind!

Do the GM LS smart coils have electronics built in to control the dwell ?
Therefore can they be operated directly from a hall effect sensor without additional electronics ?
The GM LS series smart coils require external coil drivers.

What is the function of the electronics in the smart coils ?
If you Google "LS smart coil" you'll find lots of info on the technology behind these coils.
