The thing about it is, even if the life of the pertronix isn't optimal, its still going to be longer than, and require less adjustment than points. It was a drop in modification for my 240, going to and from requires only placing a few screws and wires.

In my case one of the Pertronix on one of the Roadsters didn't last more than a couple of weeks, and even then minimal engine run time, from side yard to garage and back couple of times a week.

The ZX dizzy on the Z, except for one module failure several years ago (after lending it to "check" someone else's installation ... which I heartily opposed but was talked into and now will absolutely NOT lend) has been working for 12+ years without any problems, adjustments or repairs. Oil changes, tune-ups, etc. yes, but nothing to do with the dizzy save cleaning and re-gapping the same spark plugs. I generally take the Z to my mechanic for convenience's sake but he recommended the ZX change over for the other Z's I'm working on in order for me to source them. Sadly, there isn't a direct swap for the Roadsters although there is an individual who re-manufactures dizzies for them.

FWIW
