So I did some figuring and some testing, and the old coil was getting 6V. Ford used a resistor wire on my vehicle to keep the voltage supply to the coil at 6 instead of 12. A little more research and some advise from another forum revealed that anytime you replace the points with Pertronix it is recommended that you send 12V to the coil. I had the Pertronix put in about 10 years ago, and never knew I was running 6V all this time. So i replaced the resistor wire from the ignition switch with a 12ga normal wire so my coil would get 12V, and folks let me tell ya. I rebuilt the motor last year, many of you will remember giving me advice, and I was pretty disappointed with my power given the upgrades I did. Ran her tonight and laughed running down the road! What a difference! I don't know how much is from upgrading to a Flamethrower and how much is from providing the Pertronix with the voltage it was supposed to have all along, but this little 170 is a beast! I could probably break the tires loose if I wanted to (I don't). The fun factor of driving this old truck just increased big time. Thanks all!
