John, I think something else is the issue here. There is NO dwell setting with the Pertronix upgrade. It is the absolute definition of plug and play. I added this to the white G last year. I had accidentally pulled some of the wires loose from the points while attempting a re-detail of the distributor. Rather than screw with setting the points back up, I called John Lazenby and ordered the Pertronix. The hardest part of the install was finding a good non-obvious power source. I suspect this is where the problem at hand lies. I no longer have the instructions, but it is very specific the power requirements. I spliced in around the ballast resistor, I'd have to look at which side, I can't remember right now. Once I had it installed, I was amazed as my car was no longer a turd, it performed great! The car had always run o.k., it just never had any balls. I feel it now has the power it should have had all along now. I do not mean to imply that this improvement is strictly because of the Pertronix (I think something was set incorrectly with the points), but I am very happy with it and have no interest in switching back to points as I plan to continue driving it a lot.

For the rest of the group, Victor owns a 300F hardtop restored by Tom Cox and then owned for a bit by Thomas Powers. Very nice black hardtop. Now on to your question - and a good question it is! I noticed the same dwell readings (I kind of tend to remember a lower number, though - like 18 degrees) when I installed a Pertronix on one or two of my 413 ram cars. And all I can say is that the car(s) never ran quite right with Pertronix. I ended up removing them, reinstalling the factory dual points, and everything was much better again. Also, what brand and model plug are you using? Comments, anyone? Vic, you may want to talk to Don Verity, at d.verity@xxxxxxx ; he's got a Sun distributor machine all set up and could fix up your distributor to spec. and bench- test it ...

I haven't had it long enough to experience that problem, but with the plugs so hard to remove etc. I don't want go through it. I did replace the plugs when I got the car because it wouldn't run. The car has a pertronix replacement of the dual points with a regular coil. I took a dwell reading & it was 22 degrees. Single points should read 27to34 degrees. Could this cause the fouling do to low saturation time ? Should I put in a pertronix high voltage coil ? ------------------------ Yahoo!
