Phil.. A point... I didn't say that 3 ohms was a standard automotive coil.. to be fair.. i did say it was a standard primary resistance value.

I'm trying to locate my GM balalst resistor and coil cross reference chart. All the coils and ballast resistor combo's on that chart range from a total primary resistance value of 2.8 - 3.2 ohms.. with the vast majority of them setting right at 3 ohms.

Are you taking into account duty cycle?

Also.. your remark about jeeps?.. I recall these engines being evaluated for a military jeep evaluation.

As for the thermal advantage.. at what point do you start sacrificing 'reliable' starts and running in adverse conditions.. like lowered voltage due to worn and dirty connections.. etc.

For reference.. that last 12v square coil I gutted was potted solid to the top.. looked like epoxy potting. Note.. this was a plastic encased coil.. not a metal can encased one...
