Dragsix you bring up good info for me to research on the dizzy. When I got the truck my research pointed me to determining the motor is a 56'. The rest of the truck as far as I know was original as far as tranny. The dizzy has been replaced with a rebuilt so I will gather the number. As far as the response about Pertronix. I did read the old post and they seem to all be talking about the original units that required the drop on ring around the lobe shaft. I don't believe that is in production anymore. Mine does not have that. It's a screw on plate that takes the place of the points/condensor and picks up from the shaft lobes directly. Do I carry an extra unit in the glove box? You bet. But I also carried a spare points/condensor set when I was almost left stranded on the way to a car show when the points burned up due to the condensor failing and I just barely limped back home. Point is anything can fail and points/condensor do not grant you immunity from failure anymore than a Pertronix. And I can swap the Pertronix along the side of the road quicker than a points/condensor change out. I've been running Pertronix in my 49', my 70 GMC, and a 65 Olds 442 for years. Not a hiccup.
