Has anyone used the petronox (think it's spelled right) ignition on a 250ci engine? If so what are the pros and cons if any.
Thanks,
Mark

I had one on my 230. Now have an hei. The pertonix was just a points replacement in my old worn out dizzy. Hei is far superior IMHO.

Hy blue67fleetside, I have installed many Pertronix conversions, but none on a 250. As there is a factory H.E.I. available for that engine, that is what I would install, you could probably pick one up at a local wrecking yard for a few dollars, hope that helps.

So the Pertronix just replaces your points. I missunderstood there ad I thought it was an electronic ignition conversion. Guess for now I'll stick with whats there.

The Pertronix unit replaces the points and condenser and might require a different coil (depending on your existing coil's resistance and if you have/need a ballast resistor - I do not know if a standard 250 engine uses one).

The Pertronix is an electronic ignition but it is not a GM H.E.I. unit/clone.

The only reason I thought about switching to it was to get away from the points and condenser.

You can buy a complete Hei from skip white on ebay for 65 bucks. Plus new wires and plugs. The difference between hei and pertronix is like difference between night and day. Best bang for the buck. JMHO
