Stealth HEI and Ford eCore upgrade

As the weather is starting to get colder I'm limited as to what I can get done. One of the things I want to do is Stealth HEI and Ford eCore upgrade.

I have the write-up and diagrams from JeepHammer and they seem really easy to follow

I have some questions on the what other vehicle I can get the parts from.

JeepHammer suggests:
79 Impala V8 for the ICM
89 Escort for eCore and Plug
Capacitor --- I have no ideas were to look for that. Can't find locally since I don't really know what to ask for.

What other years and models can I get these parts from?


Wanted: I'm looking for an old ICM that has good connectors. It does not have to work and can be melted, that will fit an 84 CJ. I want the case and plugs for this project. I will pay shipping.

Any Ford from about '86 to late 90's will have the E-core coil you are looking for,
Raise the hood, find the coil wire, follow it back to the coil,
Take the coil, connector with as much of the small wires as you can get,
There might be a 'Boot' over the coil connector, if you get that, it's a bonus,
And most of them have a 'Condenser' bolted to the coil or right near it, little rectangle looking thing.

So you're looking for a junkard ignition module? Why? A new one can be had for $20. Just about any '76-80 Chevy V8 will have the ignition module you're looking for.

Good point. I was just thinking if I was there, I would look for it.

If you really wanted the used module. They're under the dizzy cap. On any HEI distributor. Heck, if your there and can get one for a $1, use it as a spare. I wouldn't make a special trip for one.
On the condenser, haha, went to O'reillys they didn't have a clue. Went to Car Quest told the guy I tuning up my car. I need plugs, points and condenser for a "69" Chevy. He looked it up. I told him I just need the condenser.

FORD MODULE & HOUSING/CONNECTORS
Any Ford Vehicle from '75 to about '83 should have the module housing you are looking for, you *Might* find one with good connectors in the junk yard, but I wouldn't hold my breath...

HEI MODULE FOR THE CONVERSION TO E-CORE COIL IGNITION...
You can pick up a module in about any parts store for around $20-$25, anything GM with a V-8 and HEI distributor, they are all the same.
There was only one module difference, Corvette and Police Cars, and they aren't made any more, so you get what the parts store has.

DIODE IN 'CRANKING' CIRCUIT TO HEI MODULE.
The diode DOES NOT build heat in this situation, does NOT need a heat sink, but the Ignition Module DOES need a heat sink and proper heat transfer paste. (Radio Shack or any computer supply store)

DO NOT use the clear dielectric grease supplied with the module in most cases! It's not designed to take the heat the module will produce, doesn't transfer heat well and generally is setting you up for a failure.

HEAT SHRINK.
If you intended to say 'Heat SHRINK' over the diode, then it's your call, do what you want.
I insulate the terminals with heat shrink a lot of the time, and I've encased the diode in heat shrink too with no problems.

'CONDENSER'
I wouldn't worry about a 'Condenser' unless you get ignition noise in the radio.
If you use a good set of plug wires like the recommended MSD set,
Then it's very unlikely you are going to get much noise in the radio.
Cheap wires make noise, not good ones.

If you do have noise, a condenser is available from every parts stores for a few bucks,
You can mount it at the module, or at the ignition coil, doesn't matter as long as it has access to positive side of the coil positive wire.

Is this the page you are working from?

I'm going to look at a family bar and figured I would walk around and look.

Again thanks for the info. I was asking about heat shrink. I was concerned with it hitting ground.

The condenser I figured I would put it in just incase. Figured better safe then sorry.

Yes that is the site I'm woking from.

Yes, if you actually need one. As said, it's job is to prevent RF noise from finding its way into your radio. With good plug wires you don't need one. You won't find many GM vehicles with HEI or Fords with Durapark II, III, or IV that use condensors.

Thank you. I figured if I'm going to do it, I only want to do it once. So fr the 2-3 dollars I would put it in, same with the Diode.

I don't know for sure. That being said,I can't imagine there would be any difference, they all do the same thing.
If you think about it, your using a Ford cap and rotor, a GM Ign module, and a Ford coil, a stock or MSD one, on a AMC engine. Personally I'd use the GM.
