looking for input on the benefits of converting to electronic.
the slant in 40 project is on the road, but they are never done.
i have considered changing to electronic, but find myself asking why?
this is a summer cruiser, and will take to events 400-500 miles at times. not going to the track with it, probably won't see over 5,000 rpm, as a little stoplight racing at times, and an occasional burnout.
i know the benefits of electronic, but am wondering if it is worth it for my application.
i don't mind changing points once in a while,and the points dizzys are more dependable in my opinion. don't need to carry p[arts incase a module od ballast resistor craps out as they are known for.
whats your thoughts??
Chuck

If you don't mind adjusting/replacing points once a year or so, then the benefits of electronic are really not much.

HEI or Pertronix are best simple conversions, IMHO.

Yes pertertronics is great. But a little pricey. And you need two. One as a spare in the trunk!!!_

You get a slight bump in power and fuel economy with HEI. It'll probably cost you between $100-200 to set up (if you get known good parts). If you really don't mind changing points then I don't see the need to make the swap.

All I can say is what I've done in the past an I've had all three.
i've been told that I am nuts for doing it this way but it always works.
1) Always with my fresh engines to run them before putting them into the car what I always use is Points. With points one always knows what is going on and if there is an ignition problem one can see it and best of all they are simple and cheap.
2) When I've used Pertronix I always buy their kit and coil if there is a problem the will replace them. (I've never had a problem) They are inexpensive and easy to install and if something goes wrong with their system just keep a set of points in the glove box problem solved.
3) I am now using the fancy MoPar performance kit works very well, costs more but works well I am told it is great, I have no complaints, nothing wrong with it I cannot if it works any better than the Pertronix units that I have used in the past or not.
4) If I was building another street engine I would most likely go with the Pertronix it is simple and inexpensive
On the street engines that I've put together after they have been running in the car I've had an ignition curve built. These are driven cars only, nothing fancy but they have always started and run without problems just set it and forget it.

I will stay away from the Pertronix as to many friends say "its great but if you are running one get a spare for trips" I have used the Mopar Hp electronic Ignition for 20 plus years in my 64 slant six with no problems. If it should go bad It can use any of the stand alone Mopar ECU's from the 70's. Most part houses carry them.

Who has seen failures with Pertronix? I don't recall hearing about common failures. You could also just carry a set of points as your spare.

We all generally carry spare parts anyways, heck I've got a spare alternator in the trunk! So to me, its not what spares you want to carry its more like:

What system do you feel like trouble shooting?
And
How much will it cost to replace the spare?

Points are cheap, MoPar EI is cheap, hand built HEI is cheap-ish, and pertronix is most expensive give or take.

I factor in conversions on ignition systems as if I were converting 2 cars, and purchase appropriately.

I really don't see any advantage to keeping points except short term costs savings. I think the cost to convert to Pertronix EI is the same or even less than converting to HEI. You can still find all the parts you need to convert to HEI in a junkyard (HEI module and slant six electronic ignition distributor) for cheap. Points may be cheaper to keep right now, but you have to replace them unlike electronic ignition. Electronic ignition is set and forget. The points distributors are basically identical to the electronic ignition distributors save for the electronics on top of the governor. HEI doesn't use a ballast resistor and the HEI modules are plentiful and cheap. Add to the the improved performance and fuel economy from HEI and I think this is a no -brainer. Switch to HEI and don't look back.

Reed's onto it.

Have a good look through the above discussion on HEI to see why it's a highly recommended mod.

Why are people scared of the pertronix failing, and having to have a backup pertronix................

The pertronix replaces the points and condenser in your existing distributor. You don't have to get the electronic distributor that you would need if you go with the Mopar or HEI conversion.


And all you do for BACKUP is put the existing points and condenser that you removed in the trunk..............

I'm not scared of Pertronix. heck, I used it in two cars i used to own. It is a great simple little system.. My hesitation at recommending pertronix is that for less money you can install the HEI system, which is a better system. So, less money and better product gets my vote.
