Since installing the Pertronix unit a couple of weeks ago in my 1969 Dodge Monaco, I've been satisfied with how the car fires up and idles and have no complaints on that system.
I was not able to have the cars timing checked by someone who knows what they're doing, but I did rotate the distributor ever-so-slightly in the clockwise direction. This did seem to improve the cars running.
For the first time since owning the car, I was able to put my foot into it and let the car almost windout in first gear. A turn in the road prohibited my going further into the RPM band, but I was quite pleased with how smooth the operation of the vehicle was.
In addition to installing the pertronix unit, I decreased by 2 or 3 in size the jets in my 670 Street Avenger Holley.
While recently taking the car out for a test drive the car suffered tama just as I was celebrating my mechanical accomplishments. The car experienced a violent event causing the air to be filled with screeching sounds, steam poured forth from under the hood, and coolant went all over the highway overpass. My celebration was quickly dashed by what turned out to be a wrench I left sitting in the engine compartment making its way into the fan, which in turn bent one of the fan blades.
The bent fan blade ripped into the radiator! A colossal mess developed on the overpass, but I did receive a free tow to the nearby garage.
I've obtained a new radiator, but I'm trying to find a new cooling fan. (Not a clutch fan.) The damaged fan has 7 blades. I assume that any replacement must also have 7 blades?
Thanks!
