Electronic ignition

I am thinking about using a Pertronix Ignitor to replace the points and condensor in my 68 conv. 327/210 hp....what are the pro's and con's of doing this? any thoughts are appreciated......everything else is stock

Re: electronic ignition

I use the Ignitor II. I can't think of any cons. The biggest pro is you don't have to worry about points adjustment any longer and if you get the Ignitor 3 for a little more money it includes multiple spark discharge and a rev limiter. You'd basically have a high output ignition comparable to an HEI in a stock looking package.

Ther is no such thing as drop a new dizzy in plug and play...that is plain simple BS
The chances of getting one out of the box that has THE CENT curve AND VA for your engine as astonomical

If it does idle better or more power it is because it is over advanced

Re: electronic ignition

Steptoe, what you said is true, but Lane and Darrell's ignitions might have been in such bad shape to begin with, that any reasonably functioning replacement ignition would have been an improvement (even one not completely dialed in).

Re: electronic ignition

As a kid, I threw a swap meet Accel dual point distributor into my '69 327/210 and it did feel better. Now I realize it was all because this distributor had a more aggressive advance curve than the stocker. I think this is what most people would feel when swapping distributors but not realize the reason why. But I also agree with Steps, that it was not likely correct for that engine.

The Pertronix kit, at least 6 years ago when I installed mine, came with shims to make sure that the endplay of the distributor shaft was within spec. Just one more thing to be aware of.

Re: electronic ignition

A dizzy is like a scope on a rifle...it bolts straight on, but still needs barrel sighting and range testing.
And timing is like shooting a deer on the run...get the lead time wrong and you either miss (engine doesnt start, or way to rough) or you have a day hike to run the deer down (engine runs ok, but since timing is out, like the deer, it dies a slow death)
Like a deer u have a 10" circle behind the shoulder...timing u need enough advance to get max cyclinder pressure about 15 to 18 degs ATDC by giving enough lead time.
And that lead time varies (hence the cent and VA adcance) as to DCR fuel type etc.
(just as a bullet weight and load varies)

That's popular with Corvette guys with judged cars, as you can't tell it's been changed from the original points due to the single black wire between the distributor and the coil. They're very reliable - have never heard of one failing. They're marketed by Lectric Limited, but they're made by M&H Fabricators.

In spite of the advertising hype, neither the Pertronix nor the Breakerless SE drop-in conversions add any spark energy; they're just electronic switches instead of electro-mechanical (points).

I was bored and took a peek at their website. It was a refreshing change from the usual marketing nonsense that infests most ignition websites. It appears that an actual engineer wrote much of the "FAQ" type descriptions of this product, as there was some reasonably accurate descriptions of what actually happens in an ignition system. The most interesting part (to me) was that this system has dynamic dwell (a key item in any intelligent inductive ignition design, IMO) which helps to prevent excessive coil/module heating at low RPMs, but also bumps up the dwell time/angle at higher RPMs to maintain desired coil energy levels (most systems will lose energy as RPM increases due to the dwell being a fixed angle). An additional item is that the module will automatically shut off the dwell in the event that the engine stalls or the key is left on. Good for safety and battery life.
I don't have any vested interest or connection with this company. I was just impressed that they were confident enough in their product to actually tell the customer what it is, rather than just selling it because of some bling factor.
