Well, I've been eyeballing that Pertronix Ignitor III unit for months now. It is advertised as having more available spark energy than the regular original Pertronix, or the following Pertronix II, supplies a multiple spark like an MSD, and has a programmable rev limiter.....all fitting inside the factory distributor.
I've been running the original Pertronix Ignitor for something like 20 years now, no problems, so I had to try out the new unit. They recommend purchasing the Ignitor III coil to go with the module, so I did. I had long ago installed the Pertronix relay kit to give the ignition a full 12 volt operating voltage so I was set.
The new III module just bolts right in, the magnet wheel that was slipped over the breaker cam for the original unit is not used, the III triggers off of the breaker cam itself....pretty simple. The Rev limiter is pre-set at 5500 from the manufacturer when you get it. I left it alone. Being a stock 351c, a higher redline isn't reasonable, and I'll likely not even rev to 5000 in normal driving, so instead of re-setting the rev limiter lower, I left it alone.
I re-installed the distributor to the engine in the same position marked when removed, installed the coil, attached the wires, turned the key, she lit immeadiately and idled nicely. ( It did before too ). Its just nice to know some manufacturers stuff actually works as advertised. I'm getting slightly better gas mileage, and acceleration is noticeably snappier. I'd say I'm happy with the addition.
Just to fine tune the car now, I think I'll open my plug gaps and adjust my total advance ( which is a bit high ), looking to run 10 initial, 34 total when all is said and done.
