What are the pros and cons to each system? I want to replace the points and still maintain a stock appearance (so no HEI). The car is a 69 Bird, 400/4 speed. I'm leaning toward the Crane because of the rev limiter and lower cost, but most people seem to have the Pertronix around here. I want to limit it to 5k rpm. Any thoughts? thanks

I'm running a crane xri right now. Rev limiter works. Made in USA. Reliable.

If I had to do it over, I would just get hei.

I dont know if the combo from the other thread needs a rev limiter. And just one more thing to go south out on the road.

Did I mention that it's reliable? Better starting. Smoother idle. If you re not getting hei, get the crane unit.

Do the units above use a variable dwell for more effective coil saturation, build up time.

Good question. The catalog doesn't say, guess I would have to call Crane. That is a good article in Hemmings. I can remember in the good ole pre-internet days trying to troubleshoot a 70s Pontiac with HEI. The car would die randomly (usually in the middle of traffic) and refuse to start for at least 10 minutes. Just long enough to exhaust the full profanity vocabulary of surrounding drivers. HEI was new to me at the time, but looking in my trusty MOTOR manual I though I could easily diagnose the problem. No such luck. My own knowledge of profanity under the hood was quickly exhausted as well as my parts budget. Never did figure it out completely.

I see there is another thread discussing this same topic, but thanks to all, especially the link to Daves small body HEI and the info about the variable dwell.
Crane XR-i is not a variable dwell unit. This unit is back ordered and can't be had for a month (poor inventory control?). However, the price is less than the Pertronix.

Pertronix Ignigtor 2 - the 2 is a variable dwell unit. The 1 is not. These are readily available from many sources.

The HEI will fit the 69 bird but I'm trying to stay with the stock (original) look as much as possible. I suspect that any of the units will work fine, better than points. There is one complaint I read about the Pertronix units - if you leave the key on you will fry the module. Anyone have that happen?

The original Pertronix ignitor was triggered off the existing points cam lobes. I ran it in a 400 many years ago for a few seasons then sold it off to an Olds guy because I had a hankering to try the then new ignitor 2 on my next motor a 455. As I stated before as well as Tom, been working trouble free in all kinds of driving situations for more than 10 years! The igntor 2 has the more reliable magnetic pickup wheel setup.

Thanks for all the feedback. I'm going with the ignitor 2. Looks like the best unit per dollar. The Crane would work too, but I didn't want to wait a month for delivery.

Cort regarding that, I'm not sure. I've never encountered that issue because I wired in a 6AL box with the required diode on the ignition "calling" wire to prevent any kind of backfeed which is highly recommended in the instructions for these ignition parts.
