petronix ignition coil
I have a 1970 302 with the petronix igniter with the petronix flame thrower coil. the coil part number is 40011, 40,000 volts, 1.5 ohms resistance. this coil does not have a ballest resistor built in. I have been running this set-up for approx. 8 years. My question is should I have a ballest resistor with this coil and should I use the 1.5 ohm or 3.0 ohm coil?

From Pertronix instructions for 12v neg ground
4. Four and six cylinder engines require a minimum of 3.0 ohms of primary resistance and eight cylinder engines require a minimum of 1.5 ohms of primary resistance. Do not remove resistors if the coil primary resistance is less than specified.
5. If your Ignition coil has the recommended primary resistance, remove or bypass all external resistors.

From that I would say you are good.
