3 ohm vs 1.5 ohm ignition coil

OK, so let's just go with that logic...it suggests that I'm OK with the 3 ohm resistor coil with the v8. It could be that Pertronix's guidance applies to their particular other peripherals, at least it seems to read that way.

Where did you read this? Please share...
I don't recall where I read it.....Unfortunately. I think it was another car forum. I was trying to figure out how to match one of my coils to the 1.5 ohm resister that I happened to have....I ended up using the coil that totalled between 2.3 and 3 ohms. This is on my run stand.
