None of the above. Start with an electronic distributor and do the HEI upgrade.

Too many people who were born on third base actually believe they've hit a triple.

My pertronix ( I'm assuming this is what you mean) went bad in my '72 Valiant not too long ago and I switched back to points.....I never replaced the pertronix and I have been getting Standard brand points from Rock. I eventually will go with Dans advice.

I have on, with a orange Cdi box. I am having a hell of a time wiring it. I have wired per the wire diagram checked my coil replaced my ballasted resister and still don't have spark at the coil. Also my other dizzy as been balanced and reweighted. Any suggestions

My suggestion is to follow Dan's advice & go with the HEI system- it's fairly cheap, effective, & reliable. Hook everything to the car but don't install the distributor yet. Fit a gap-type spark tester to the coil output lead, turn the ign key ON & spin the dist by hand- should have lots of spark. Install the dist, fire it up, set timing, then forget about it.
