I second petronix. Just seems like the I is almost bullet proof if you dont need the bells and whistles. The III I do not use due to the plastic plate pivot point cracks. Still works well though. Another big plus is it still retains your original curve in your distributor.
The new Mopar kits are all made overseas and they have a big issue with the orange "relaces xxx" ecu and also a serious fast curve more for the strip. There are other one wires out there really depends what you want to do and the curve needed.
Pertronix I Has worked for me for over 20 years in many cars.
I suggest to read the instructions throughly which ever you choose.
I II III as they require different coils, and depending on model some require ballast by-pass.
Ran the Pertronix I in this Hemi that revs well past 6,000 rpm.Worked flawless.
I had linked the III because it's the most advanced, multi-spark and rev limiter, and that is the "module" the billet aluminum Pertronix distributor I got for my wife's GTO has, although I bought it as a complete system.
I was going to switch from my FBO ignition system to Pertronix, just because I am a strong believer in the importance of the ignition system and I wanted to try something different, but once the Progression Ignition system came to my attention, my ignition system search is over.
