Anyone got an opinion about Pertronix?

Talked to some dude the other day and during the conversation he suggested I get a Pertronix ignition system for the Points type distributor for my very near stock 69 Firebird. I watched a video about how to install it on youtube and it appears to replace both the points and condenser inside the distributor with what I think is a little computer. Is it a good idea to buy this system or not? Different brand?

I have ran the petronix conversions in 4 or 5 rides and only had trouble one time and it was my bad not the petronix kit.
I really like them easy to install and can be change back to points whenever you want, I would keep the points and things in the console or glove box just in case you ever do need them never know. JMO
I say go for it ex-specially if your trying to keep the original stock look of the engine/bay area.

I agree. I've used their products with no problem. One example is my IH gas backhoe. It was an impossible pain to start until I converted it to Pertronix ign.. Fires off every time now..

I've had very good service out of pertronix products. Sure can't say that about accel.

The latest Street Rodder mag has a DIY write up on doing this conversion. I've never used it so have no personal experience since I always will go with either a full MSD, (dist, coil, box) or at least a box and coil

pertronix

i've used them in my bucket for yrs... untill i changed the coil to a almost zero resistance and smoked the ign sys...
U GOTTA RUN A BALLAST RESISTOR.. i replaced it with a mallory sys (same as pertronix) and working fine.. they both work great .. but make sure u have the resistance.. period !!!!

I bought a crane PS20 not too long ago. It came with a ceramic block thing. Is that a ballast? Right now I am thinking that a ballast creates resistance. Brings down the 12v from the batt to 8v so it doesn't fry the electronic points. Whereas a HEI system would want 12v right? Why does it need resistance anyway, I don't get it.

That should be the "BALLAST RISISTOR" but it's not needed on every application the 3 or 4 times i used it was without the Ballast worked fine for me, but remember some will have to have one but not all if your ride calls for one then i would use one. JMO And the Ballast is for reducing the voltage to the coil. And an ignition system that used a 12v coil with a 12v feed from the battery from the ignition switch don't need or didn't come with a "BALLAST RISISTOR " JMO

Jmo

One more thing what ever you do be sure to run the correct coil with whichever system you go with, they do have Ballast coils out there if needed.
IIRC if you have a 12v with the 12v from the switch when you hook up to the Ballast it should brake it down to a 9v feed. someone elsse might chime in if i left something out.

I've got Pertronix conversion kit in two of my ride. The one in my 427 ha been there for 13 years. I used to carry the points and condensor to change if the Pertronix failed, but I tossed them after 5-6 years with no issues.
Just put another conversion in the 327 in my gasser about a year ago, but it's working great so far.

A lot of cars have a built in resistor and you wont need a ballast resistor ( you have to bypass this wire if you have to use the ballast thats to your new ignition system!) if you use both, your car will still run but your really cutting down saturation and it wont run with the performance it could have and youll never know it! Early GM vehicles have a white wire looks like its wrapped in fiber glass going to the coil that wire is the resistor! Other vehicles have a different size of wire built into the system reducing the output (the smaller the diameter or the different material in the wire the more the resistance) a lot of Chrystlers have a ceramic ballast for their ignitions make sure you dont use the stock one if one is on the car!! (use one with the ohm rating that your ignition calls for). Some coils have the resistor built right into them too.
A resistor cuts down the amperage And just a little to high an amperage is what will fry your system (like a little too much will fry a diod right now)

I see this mistake with the built in resitors done on many cars and by very smart people so its not a hard mistake to make! Some built in resistors are in the harness hid under the dash hard to find!

I didnt answer your question (its already answered) I just thought you may not know this.

Oh by the way if you see a chevy with that little white wire hooked to a ballast resistor dont tell him if your at a track it will give you an edg. Same thing if you see "built in resistor" printed on his coil and hes running a ballast resistor

I've heard that if the resistor is left in ahead of an electronic ignition system like the Pertronix, it can cause a failure from a low voltage condition.
