The ignitor ii goes right in a factory dist and is like $160....
So… in 2025, what’s the best electronic ignition conversion?

cost of aftermarket distributors is out of control. Been using factory type magnetic pickup and re-curve them, then a CD ignition box.
Lately been converting to EFI, locking out factory type and re-phasing the reluctor or using the lean burn distributor, the EFI controls the advance and triggers a CD ignition box.

I’ll probably go for a new distributor as it’s the original and the car has 120,000 miles on it. I will shop around though. Thanks!

Other option is have @HALIFAXHOPS setup a dist for you.... that's all he does and seems to live for
He setup mine and sold it to me...

The coolest thing about the Pertronix units is that they look relatively stock.

Pertronix in my car plus their coil. Must bypass the ballast resistor. Been using them over the years and never had any problems.

Pertronix is the way to go.Put it in my 66 big block Dodge, when I had it. Works great easy install,very reasonable price.

I've used the Pertronics kits on my 68 426 Hemi and on my current 67 Satellite 383. Easy to install, and looks fairly stock. To keep the original look, I soldered a wire into the back of the firewall resistor, so you can leave it where it is. It's not required on the Pertronics system. Some models of the Pertronics kits also have a built in rev limiter.

Looking to buy a Ignitor 1 or Ignitor 2 to put in a dual point distributor.
I have an old stock coil. Will they work with Ignitor 1 ??

Did I mention that the Pertronix is also multi spark discharge with a built in rev limiter? No ugly box to mount anywhere.

Aaaaaah, yes. The Pert 4 pin HEI type module that multi sparks to the redline. When I emailed Pert to ask how it works, I got no reply...
I do not believe the Pert claim that it is electrically possible to provide multi spark with ONE coil & 8 cyls in a 4 pin module.
For these reasons:
- it would be the 8th wonder of the world.
- it would be a very desirable ign component
- & as such, you would have something nobody else has & you would patent it [ if it really worked ]
- no other company has it when it would be easy to pull the module apart, see what is in it...& copy it.
I do not see that this device could be capacitor discharge ign system because CD requires a sizeable transformer & large capacitor. MSD boxes such as 6, 7 are CD & require a box to house these large components.
That leaves the inductive ign [ II ]system which has it's own limitations. With II, the coil takes time to fully charge [ saturate ] the coil. With only one coil & lots of cyls such as an 8 cyl engine, you run out of time at higher rpms to fully charge the coil. GM's HEI solved the problem by using variable dwell. But you still have limited time & I can see no way that TWO sparks per cyl could be generated at 7000 rpm.

A new CH-181 Pertronix for my 77 318 arrived yesterday.
I was concerned the stock ignition was quite old, and might be difficult to fix if I got stuck somewhere.
I have Pertronix in my 41 Ford tractor. It has been working well for many years.
Box says made in US.

Oh good we are talking about ignition again. The sun came out today so went for a drive and my HEI module died. I have 1100 miles on the car and this is the fourth module I have put in it. Getting real good at swapping them on the side of the road. It is a stock Chrysler electronic ignition distributor with the module mounted to the bottom on a heat sink. New pickup coil. New high energy coil. Ground wire directly to module mount screw from the same bolt where batt negative is on head. Powered by blue/brown wires from ignition switch wired together- no resistor.
I am now thinking they must be getting fried by too much continuous voltage. I have a small digital volt meter in a USB receptacle that I installed in the cig lighter hole. It reads 14.5 volts while cruising with no lights on.
Is this too much voltage? I have an adjustable voltage regulator, so I think I will try and dial it back a tad and see if that helps.
I can not find a definitive answer on how much is too much voltage for the HEI modules.
