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
