Absolutely 3.0 ohms.  The 1.5 ohms is for the cars that have a ballast resister built in

 

Pertronix makes a flame thrower coil which is excellent.

 

Also, btw, Pertronix tech support is really wonderful.  I had ordered the wrong part on an igniter set which previously had failed but out of warranty.  I called tech support and they sent me the correct part free!

The instruction sheet I found has this:

Q. What type of coil do I need?
A. The ignitor is compatible only with a “points type” coil. Eight cylinder engines require a minimum of 1.5 Ohms of resistance in the primary circuit. Four & six cylinder engines require a minimum of 3.0 Ohms of primary resistance 

So, it sounds like the 3.0 Ohm.

Anyone know if we should be using a 1.5 ohm or 3.0 ohm flame thrower coil
