Can't tell for sure if it's more powerful since I've never done any timed runs with it. I do know however, that it idles more smoothly. The big difference I've found so far is that the gas mileage over the first 100 miles jumped from the dismal 12 mpg it was getting to 17 mpg--nearly a 50% increase! The old points were not in bad shape but the wiring to the ballast resistor and coil were frayed. I highly recommend the changeover based on my first 100 miles. ---------- Delco - Pertronix Delco window style distributor. Fitted with a Pertronix it's performed admirably but I've never been able to get the centrifugal advance where it is supposed to be. There is enough travel but it didn't come in fast enough. It seemed there was no combination of springs and weights that would give me the total advance needed at the recommended 1600 rpm. I have been getting close but even when I thought I had it right, it would seem to change the next time I checked. Today I decided to try another combination of springs and went to very light tension that would still snap the weights back when I let it go. BUT, when I put the rotor on it wouldn't snap back without help. I loosened the rotor just a little and it would return just fine. At first I thought that somehow tightening the rotor down was causing enough flex the advance plate to cause binding. Realizing that there just isn't enough force to cause the metal plate to bend I looked at the inside of the rotor and could see a little shiny spot on the molded in bracing. 20 seconds of filing and the advance comes in quicker and returns to where it is supposed to be. Ernie ================================================= Just finished installing a Pertronix P/N 1162 breakerless electronic igniton in my 66 Commander Six. This was one of the easiest jobs which I have ever done. Took only about 20 minutes and the distributor does not have to come out. All that you need to do is loosen the two screws that hold the ditributor cap in place and remove the cap and rotor. You then remove the two screws that hold the breaker plate in place (as an assembly with the points in place), and remove the plate. The new Pertronix plate is put in place making sure that the pin on the plate is inserted in the arm on the vaacuum advance. The two original point plate screws are tightened to hold it. You then slip the reluctor over the distributor cam, push the rotor back in place to hold the reluctor and using the enclosed plastic feeler gauge, set the gap between the module and reluctor to about .030" . The nuts holding the module are then tighened and no further adjustment is ever necessary. The electrical hookup is simple: black wire from the module is attached to the coil - (dist terminal) and red wire from the module to the + (Bat/ignition) side of the coil. The only slight mod is that you must file a small slot in the distributor cap where is goes over the new module strain relief bushing which is slightly bigger that the stock one. My Stude started on the first crank and runs fine. You are not supposed to use any primary resistance in the + ign lead but the 1.5 ohms of the resistance wire does not seem sufficient to harm anything. Now I can drive with no worry of point block wear altering the timing and I'm getting better performance and mileage to boot. This is a easy bolt on for those of you thinking about going the electronic ignition route. The Pertronix also does not alter the appearance of the coil or the distributor as the module is completely hidden within the distributor.
