i am going to convert my slant to electronic ign. using a mopar electronic dizzy, and hei module. i don't have a dizzy yet, and don't want to end up with a lean burn dizzy.
what year, model dizzy should i be looking for.

What year model car or truck do you have?

This is a dizzy that can be used with the electronic ignition cardone 30-3690

Other people on the forum may have other models to recommend...

I just today plugged my lean burn module back in...i have been running the mopar style ECU for about 4 months now and after replacing my distributor about 2 weeks ago that has a working vacuum canister i've had some problems tuning the vacuum advance and decided to give the lean burn a go again. My old distributors vacuum can wasn't pulling any vacuum and i was running it with just mechanical advance and didn't realize it until i tested it with a vacuum pump...

I think the lean burn module may get a bad rap!!!

I converted to ECU because i thought the lean burn may not have been tuning right (because i didn't have a lean burn carb, dizzy, and some of the other pieces) LOL. But the problem ended up being a clogged cat...

Today, i plugged the vacuum can and carb vacuums and disconnected the mopar ECU and connected the lean burn stuff back up and the truck seems to be running good and advancing nicely. I'm going to check with my timing light to see how much advancement i'm getting compared to just the mechanical advance which was about 34 total timing.

So, right now, i'm running the lean burn with a holley 1920 carb, a 30-3690 electronic distributor, no cats, no egr, no smog pump. I modified my the air cleaner so it gets 360 air. I have my truck set up for both lean burn and ECU which gives me a backup ignition system if i need it! And allows me to test between the two and see which one i like better. I do think the lean burn module provides a hotter spark compared to the mopar ECU...The HEI is suppose to have alot hotter spark too

My recommendation is to try them both and see which one you like better. I'm not sure what the difference is between a lean burn dizzy and an ECU dizzy. If one just has a vacuum can and the other doesn't but i wouldn't get rid of your lean burn stuff try them both. If your vehicle isn't running right it may not be the lean burn setup but something else...

i have a 41 plymouth buisness coupe witha a-833 od trans. the engine is a 77 model , extensive head work comp at 10.0:1 howard cam, edelbrock 4 bbl, and dual exhaust. it was, and is currently back to a points dizzy. after two pertronix failures in about 1500 miles. i want to convert to mopar electronic dizzy, and gm hei. , but thinking seriously about staying with points, as i only drive the car about 1500 miles a year, and i can give it a tune every winter. nothing better to do in wisconsin in winter months.

Ok, so your not running a lean burn setup at this time...i figured you might have a 80's era car or truck and wanted to switch to an electronic ignition system to get away from lean burn since a lot of people don't like it.

The cardone 30-3690 is a electronic pickup coil dizzy that you can use to get away from the points dizzy. You can usually tell the lean burn dizzy's because they don't come with a vacuum advance canister.

Outside of the pertronix failures did the motor seem to run and advance good?

Hopefully, some of the more advanced people will chime in and give you advice and tech info about converting from the points, pertronix setup to electronic, HEI

If you have a lot of free time during the winter months you might as well try out a different ignition setup and see if you like it better...

Remember that lean burn systems came in several varieties. There were carb only systems, distributor only systems, and carb and distributor systems.

HEI is superior to the factory Mopar electronic ignition, but if you already have Mopar electronic ignition it probably won't make a noticeable difference to switch to HEI on a street driven car. Points are stone age technology and should be replaced for improved performance, reduced maintenance, and improved fuel economy. Lean burn is a crap shoot. If you have a working system it is only a matter of time unit it fails. It is extremely hard to find replacement parts for the lean burn system, so most people end up dumping it.

You might get just about anything with that Cardone reman. If you can find an early ('78-'80) Super Six distributor in a wrecking yard that hasn't been through the A1 Cardone wringer you'll be better off. Otherwise you may get an earlier distributor with a lot more mechanical advance than you want or need.

no no, i don't want to go to lean burn. i just want an electronic system that i don't have to worry about installing a new module along side of the road!!
it ran great has a advance kit installed, with the pertronix till they failed. one at 800 miles, and another at 500 miles. i have been in contact with patrick from pertronix r&d.
done all the power and ground checks. checked the resistance of all plug wires (they want over 500 ohms)
sooooo, i'm thinking about the mopar-hei set up that seems to be working so well with othere

Thanks for the info...i didn't realize that. I checked my timing and saw that without a lean burn dizzy i'm still just using mechanical advance. It looks like with my setup the lean burn is just acting as an ignitor but i do feel like it does a better job than the mopar style ECU and provides a hotter spark. Just by how the truck starts and runs

Later on, if i find a good deal on a lean burn dizzy i might buy it and put it in just to see how it runs and advances. And do the same with a holley 1945 carb too

Winter's on it's way, so YES, you might as well try the HEI ignition system out...I'm sure if you do it correctly, it will be stable

Uhhhhh, no. If you have a computer controlled ignition then the computer controls the timing. If you are using a standard electronic ignition distributor with a computer that controls the timing, I don't know what the heck your timing is doing. If you have no vacuum hose attached to the vacuum fitting on the lean burn computer, then your computer will go to a default timing map, most likely a static advance setting (this is a pure guess, though). I do know that the timing advance built into the computer will not function correctly if the vacuum is disconnected.

If you are running a distributor that has a mechanical advance mechanism then yes, the timing will also be advance through that mechanism.

The end result is that you will have a very screwey timing advance map that will not be anywhere near optimal. You need to pick an ignition system and go with that complete system. Either all lean burn or all distributor.

Also, seat-of-your-pants is a very very poor way to measure anything. You need to at least keep a log book and measure fuel economy over several tankfuls.

yes, i sgree with reed. you can't mix and match with the lean burn stuff..
i just bought a mopar non lean burn rebuilt dizzy, and have a couplr good hei modules around here. will be going with that setup this winter. apparently gm. had a unit on some trucks? that incorporated the module and coil, and heat sink into one unit. does anybody remember this, and what model and year would i be looking for???

Right now, that's the way i'm running it. Later on i will try out a lean burn distributor and a holley 1945 carb.
I don't have the vacuum transducer connected...i'm going to test it to see if it still holds vacuum. I think your right, based on my computer knowledge i felt like the lean burn would go into a default mode because it doesn't have all of it's sensor gathering info.
My manual says that the vacuum transducer

"signal tells the computer what engine vacuum is. Engine vacuum is one of the factors that will determine how the computer will advance/retard ignition timing and change the air fuel ratio of the carburetor."

I haven't tried connecting the tranducer to vacuum yet but i will and see what happens...
Right now, i'm just experimenting between the two if i do go all distributor i will setup the HEI ignition...in time i will get more of the lean burn pieces to see which one i like better

I will guarantee you that the HEI system will be better, especially if you want to do any sort of modifications to the engine. The lean burn systems are notoriously problem prone and are difficult and expensive to repair. HEI is just a superior system.

I'll take your word for it Reed and in time setup the HEI ignition...keep it simple i plan on keeping the truck so there's plenty of time to make it better. Right now, it's not running too bad and it's a lot better than when i got it. I only put about 400 miles a month on it, so perfect tuning isn't mission critical right now...but it's nice if you can achieve it

Thanks for all the advice and info you've given me so far since i joined the /6 forum
