Pointless distributor conversion
Although the underlying science concerning reliability is universal the aircraft industry parameters applied (largely due to safety), based on the science, are not.
Which is why aircraft engines are overhauled after several hundred hours and the systems have so much redundancy. When I worked as an engineer on Navy/Marine aircraft every part I touched had my personal "artisan's stamp" on the permanent paperwork (# 4AC97) - I remember the number 35 years later! If one of my components failed (and God forbid a life lost) I was directly responsible.
The consequences of being stranded roadside are considerably less than a system failure at 35,000 feet and 500 MPH....so we should be careful with such comparisons. The science is relevant but its application is vastly different.
When our C1s and C2s break the sound barrier (see pic) I'll be a little more concerned about breaking down !!

But we have drifted far from the topic - it appears that the OP has 4 options:
1) Stay with points
2) Install a points 'under the cap' electronic conversion.
3) Install a complete electronic ignition control system (e.g. an MSD with advanced tuning capability)
4) Install a hybrid (with an electronic box controlled by the factory points acting only as a switch)
Discussions have been presented pros/cons (largely anecdotal) for each option and so he must decide which approach he wants to tackle.

Modern cars have all sorts of warning lights to advise when the vehicle is operating in an abnormal state and have a multitude of back up systems to get you home. The flow down of technology from space-> aviation-> automotive applications is nothing new. I once came across some drawings for the brakes on a mid 50s Fokker aircraft. Guess what showed up on Corvettes less than 10 years later? Almost a spitting image.
My experience (I received my 30 year service pin at work yesterday) is in the design manufacturing and reliability engineering end in the civilian sector. I work at world's largest gas turbine engine manufacturer. The word 'dependable' is in our logo.
But as you said, we digress.
There are several other point elimination units on the market, but after my experience with the Ignitor II I'm hesitant to experiment. Removing and reinstalling a distributor is NOT my idea of a pleasant way to spend a few hours.
Does anyone have any experience and recomendations on which conversion unit to use?
I've been following this post for some time and I agree with Tom and Frank regarding the conversion kits. I've personally been using the Lectric Limited Breakerless unit for years in my '62 and it's performed flawlessly. The main reason that I went to the conversion unit was to eliminate "spark scatter". I was having trouble with spark knock and the associated difficulties. I rebuilt the distributor with the conversion unit, new advance springs and weights, vacuum canister, etc, etc, etc,. Installed new plugs and wires. Had Bob Kunz rebuild the carb and she's been running like a dream ever since. Take the time to do it right and you should have no problems! My $.02 worth.
Sounds like you got plenty of opinions on what to do or not to do.
Many years ago (to many to remember) I installed a new product ( back then)
Mallory uni-lite point replacement and a higher voltage coil. I always kept a set of points
in the glove box (just in case) Well after a dozen years @50,000 miles and several eng. rebuilds the points are still in the glove box. Its on all my older cars, never had one fail.
Hummm... I did buy a spare module years ago also. I guess I should put that in the glove box also, according so some posts it must be pure dang luck it's lasted so dang long?

Hmm. 64 threads. Apparently this is a hot button subject.

I don't think an automobile 'brake warning light' quite compares to a 'Master Caution' light on an aircraft instrument panel.
Congrats on your 30-year pin (seriously)...but I earned my spurs in the aviation industry and the comparisons pale pretty quickly between those requirements and nearly anything else except space flight.
