Technical ELECTRICAL, Adaptin' a MoPar elec ign to the Flatty

Hey Jon,

Thanks for the post - I can tell you, I've been looking forward to this for a long time as well! Killer!!!!

Here is a copy of that wiring diagram...



Danny

 

Im glad to see the Mopar conversion finally taking hold. Ive been doing them for years and as you say; BULLETPROOF!!

I just use the whole boneyard setup. Dizzy, module, resistor, coil and as much wiring attached to the connectors that I can get. Even the resistor relay if you want to bypass the resistor in the key Start position and go thru the resistor on Run.

In the US there are several dizzys for the 318/340/360 so watch what you get. You dont want the later smog crappers that use the double pickups nor the lean burn version.

I have the machine work done in a shop so I dont know the full procedure; gave him Aussie Mike Davidsons book and let him alone.

You might want to include some sketches of what is necessary with dimensions. Im sure there will be lots of Mopars missing their dizzys.

 

286, I just PM'd you.

 

What was the procedure used to lengthen the shaft? Cut and weld with a sleeve? Or did I miss that?

Good information! Thanks!!

 

Excellent info guys.Very well done.

Is that a spare coil,or just testing parts ?
And didn't the Chryslers have a reputation for
Ballast Resistors going bad with no notice ?

 

Guys Ive run these dissys/ignitions on anything from stockers to 9 sec small block MoPars with much success.

Yes, stay away from the ELB and dual pick up versions, thats easy enough to do as the bulk of them were single pickup, pre ELB, at least Down Under.

Ive never had a problem with ballast resisitors, if the box is grounded properly you should be good to go, PERMANENTLY. Ive also never had a box crap out on me either.

Unkl, that silver coil is the original one with the original flatty dissy. Will be removed and will remount the red coil in its place.

Danny,

Great job on the wiring diagram!

Thanks!

 

Hey Mate,

Sorry I really should have explained everything from the start. The machine shop makes up a whole new shaft. The top is machined to accept the mopar pickup and advance plate etc in the housing, and the bottom is machined to accept the gear drive and the new shaft is the overall legnth. Imagine if you got the top half of the mopar shaf and welded it to the bottom half of the flathead, thats what it would look like. You may be able to cut/weld/sleeve but we just asked them to make up a whole new shaft.

It cost stuff all for the shop to machine up a new shaft, turn down the outside of the housing, check and recondition the dizzy pickup etc so we just let the pro's do it. I'm sure you could do it yourself but seeing as I dont have the experience I cant really give you the finer points.

Hi Ian,

The orginal builder mounted one of the coils in a very wierd way which made it hard to remove without removing alot of other parts before it. We were in a hurry to test the install and see how it would go so we just zip tied the replacement coil to the old one. Its not sano but did the job and leaves me to replace the old one when I can.

I've heard the rumours about the old ballast restistors crapping out randomly but I figure I'll just carry a spare! Cant be any worse the SHIT SHIT SHIT stock dizzy with its condensor thats lucky to last 5km or the wierd little wire that sits under the advance plate and will ground out whenever it feels like it. The way we did the wiring and mouted the ballast restistor makes it a 30 second job to replace.

Hey Merc,

I actually (through ignorance) purchased a Autolite dizzy from a 277 or 273? No wonder the guys at the spare parts shop couldnt figure out why a Bosch or Lucas cap wouldnt fit!

Here is another page,doing basicly the same thing:

Hey Ian,

Thanks for posting!

Just for those who may not be aware of the difference, adapting the pickup assembly to a later 8BA style distributer will not solve the problem. One of the real issues with the dizzy is its wierd advance mechanism. You really have to replace the whole dizzy to resolve this issue. The earlier front mount dizzy's do not suffer from this problem so mounting the Mopar pickup gives them a real boost.

That's the one I was thinking of! THANKS! Got it saved now (again?)!
