Tom Langdon makes a mini HEI that bolts right in makes a good spark, but it is high $$$$!
The pertronix is NOT actualy a electronic ignition it only replaces the points.
There are several modules from Jacobs, Accel and AMD. Some of them will work on the Stovebolts. Some of them are even programmable with a Laptop. All need 12 V. A bit over the top for an old iron.
I bought a electronic SIRIUS ignition here in Germany from a guy who is a retired engeneer for the Porsche Ignitions.
Every box is handmade by this guy, even the copper windings and solid state circiults. Here you se how the ignition box build:
Germany craftmanship at work 
Big difference is:
You keep everything stock.
No whatever modifications - only 2 cables to reconnect.
You keep original points and distributer
B U T: points last forever - because only a minimal current is used there to trigger the ignition box plus you never need to set the dwell again.
Here is some information from his website:
SIRIUS represents the newest state of engineering of electronic ignition devices. Most of the particular facts of SIRIUS exceeds those of the usual thyristor and transistor ignitions at all important and those of the modern electronic ignitions in luxury cars in several points. SIRIUS can fit nearly all motor vehicles with coil and breaker point ignition and 12 or 6 volts battery.
1. Operates from 4,0 up to 18 volts, that means one unit fits 6 and 12 volt vehicles.
2. At 6 volts and 4cyl. engine up to 5000 rpm, at 12 volts up to 10000 rpm with the build-in normal ignition coil.
3. Always the same spark power in the whole voltage range (at 4,0 volts too).
4. No decrease of the ignition power up to the highest rpm with the normal ignition coil.
5. 30% higher ignition power at 20 degrees centigrade, also with the normal coil.
6. Increasing ignition power at decreasing temperature; 100% more that means double ignition power at 20° centigrade below zero. Best start conditions in winter.
7. No current flow through the coil, when ignition is switched on, the breaker point is closed and the engine is not running.
8. Automatic adaption of the spark voltage to the spark plug air gap.
9. Best ignition spark: DC spark with a duration of .5 to 1.5 ms; no AC spark with all ist disadvantages.
10. Durability of the breaker point much more than 100 000 Km (70 000 miles), no contact eroding.
11. No adjusting of the dwell necessary, the opening of the breaker point controls the whole igniting procedure.
12. Build-in indicator lamp, usable for testing contact circuitry and to adjust and test the trigger point of ignition.
13. All build-in ignition parts remain in the car (like ignition coil, breaker point and condenser). Makes installation and rebuild easy.
14. Works together with any breaker point ignition coil you like, as well as the exotic double-coils of Citroën’s 2CV.
15. Easy to install: Mount SIRIUS at a suitable place with screws, connect cables and fix them. Ready, that’s all.
I asked him if I can use it on a 6 Volt system and the inline 6. He says he modifies the box for me for free to run on a 6 cylinder engine.
It is one of the best improvements I ever did for the 41. Starts like a modern car, idles smooth, drives like never bevore, better HP and milage.
Oh boy, I sound like one of those cheesy guys on sales TV...
... and NO! I don`t get any money for that.
I just think this is the best device for our Stovebolts and want to share the information.
Oh, here is the website (english version)
SIRIUS IGNITION Don´t get fooled by the website design, this guy is an engeneer not a website designer. :rolleyes:
