1971 slant six 225 no spark or weak spark at plugs?

After watching that video, and another, I don't think I want my original radiator to be my guinea pig for figuring out radiator repair.

I called Glen Ray and they are 5 months out. My local shop charges Glen Ray prices but doesn't have the same reputation, so for now I'm gonna try some AC Delco 10-108 coolant system seal tabs. Hopefully they can stop the leak. If not, I will likely be buying a champion radiator cc527 to use until the original is rebuilt.


I need to look into the extended design rotors as well, or possibly shim rotor on the wve set, I think it is sitting too low. I don't want to keep running this old cap and rotor much longer, they are getting pretty burnt up
