How many grounds do you have from the block to firewall/frame, and how good are they?
If you ever find yourself in a fair fight, your tactics suck.

What resistance does your new coil have/what resistance were you using? IIRC, there are 3 specs available.

sounds like you're hooking the coil up, with no resistor, to a full 12v.  The pertronix ignition unit needs a full 12v. The coil needs to be on a resisted circut. the best way to go with a pertronix ignition is to go from the high side of the resistor to the module, and from the low side of the resistor, to the coil. A full 12v hot lead will burn a coil up in.... well, apparently about 500 miles.

The pertronix coil wants a full 12V.. At least the newer ones do.....

Correct; 8v-12v to be exact. I suspect a compatibility issue somewhere in the circuit, or too much resistance.

I may be wrong (it happens), but I think you guys are enterpreting something wrong. Its the "PERTRONIX IGNITION SYSTEM" that needs full 12v. Any coil should not be hooked to a non-resisted source, from a non-regulated alternator. What we're talking about really doesn't have as much to do with the coil, as it does the charging system. If its an older car, with an older non-regulated alternator (is it?), then it needs a resistor before the coil. period. I've used pertronix flamethrower, and flamethrower II systems. I am confident that the FT-2 coil wants a resisted or regulated lead. Now, if its a FT-3 coil, I'm willing to listen, but we're still talking charging system more than we are coil. Chase it around if you like, but I'd try re-installing the resistor before I added another new coil, and see if that doesn't work just fine.

So, in essence, we were both somewhat correct, because if he's NOT using an ignitor II, or CD type ignition, then he does need the resistor. He makes no mention of the ignition system. (???) but look again at what you wrote.... it never said they want a full 12v. It says the resistor MAY be removed if using the optimum ignition system.
We need to know what ignition he's using.

Very true, based on memory I would have sworn the instructions said to bypass the ballast resistor... I do believe full 12 volts will let the system work better.....

Well! I contacted Petronix today and they tell me that they have been having problems with the epoxy filled coil (made in china...) and said they'd send me a new oil filled one which "should correct the problem"
HMM, I wonder If I should contact them and get an oil filled one before I get left stranded??

I had a simular problem with my ignitor II soo I called the pertronix tech line.. The module went bad me after less then 3wks.. Aint after market parts fun glad you got it going

I had a Petronix setup that worked great until the underhood temps settled in after awhile.
Turned out that my 12 volt source wasn't after the temps went up. I found a better source for the keyd 12 and never had a problem after that.
That was years ago before this China thing got rolling big.
I want my fair share
