This past spring I installed one on a '73 Ford Ranchero 351c.The improvement in drive ability was astounding.It starts and runs like a modern car for a change.Today I put one on my '63 Ford 2000,converted to 12 volt negative ground by a previous owner,good results were immediate.It started right up and after reaching operating temperature a smooth idle was attained at 500 RPM,down from the 600 required to be smooth before.I ran it for 3 hours box blading and bush hogging,throttle response was ok before but better now.I'd been using name brand ignition parts in both for several years,but they had that "made in china" odor about them.The Ranchero was always out of tune,the tractor less so but enough to be aggravating.It recently sat under cover for a month during an almost biblical drought and it took an emery board on the points to make it run.There must be a downside to using these kits,so I'm in for a surprise down the road or row.

Perhaps we have beaten this horse enough? That said, and as for the Hot Rod ET comparison, back in the day I ran an altered coupe with a full house flathead that just happened to use a Vertex mag. The 4" crank didn't allow the kind of RPM that would float the mag's POINTS, but it was more reliable and let me run without the added weight of a battery.

I"ve had a Pertronix in my "54 TO-30 for three yewars and have had no problem with it. I get instant starts and smooth running. The only thing you have to remember is to not leave the ignition key on. It can cause the unit to overheat and fail IF the distributor shaft is positioned to charge the coil. The instructions From Pertronix warn of the probelm.

Boley,

I have had the same astounding results on every single vehicle that I have converted with a Pertronix kit. In fact, most of them need the belts tightened as they squeal when reving the engine because the engine is accelerating at a much faster rate than before.

For those that don't think there is a change, much less a noticeable one ----> well, we all have our opinions. I got mine by actually doing conversions on about a half dozen of my cars and 2 dozen + cars / trucks for buddies. (The curse of being handy and having a nice work shop!)

Setting a big fat spark off at the right time every time does make a difference. One that can be seen on the dyno, at the track and at the pump. Do a little research and see if I'm right or not.

The original type Pertonix unit simply CAN'T get more spark out of a given coil than a good set of points can.

AND, the original Pertronix Ignitor CAN NOT drive a real "HOT" coil without getting killed trying.

Pertronix now makes the "Ignitor II" (NOT available for many applications) which is said to be capable of driving low impedance HOT coils safely, for a HOT spark.

A little over a year ago, I installed one of those one a Ford truck, and it rewarded me by failing within a day or two, right in the middle of harvest. A standard coil was used, NOT an exotic "HOT" coil.

I had a REAL happy customer, as it would take 10 to 14 days to get a replacment in by special order.

The "smoked" Ignitor II was tossed in the trash, and an alternative EI was installed, which is still functioning.

Outside of eliminating points maintenance, ONE place the Pertronix units DO "shine" is when installed on distributors with some bushing wear (cam wobble). Under this circumstance, they will provide a much more stable spark than points.

I had one fail in a '72 F250 with 390 engine when it quit was in the middle of a major rain storm, it backfired so hard it split the muffler. Had to reinstall the points to get home. The thing I never quite figured out was whether or not to have a resister in series with the Perlux system, the instructions were vague on that. bjr

No downside just money -- you can also retrofit fuelinjection, a mass airflow sensor, crank position sensor and tie it into a computer. I think you would see quite a performance increase. Of course for me the points and such work good enough, I just hate to spend the extra money.

THE downside is that once in a while those things DO fail, and then you're in "tennis shoe mode" until you get a replacement unit, or pop the points back in 'til a replacement EI unit can be ordered in.

There's NO "file the points" to get back to the yard" option here.

Happen to me while speading manure,luckily it was the coil,threw in the old coil and got her back to the house.They replaced the coil for free.

The vastly improved performance claims are good for a laugh.Once the fuel air mix ingites it doesnt matter what was used to set it off.I am having a hard time buying gas for my tractor.No money left for 100.00 ignitions.The oil co. are stealing 200.00 bucks from my SS check every month now.100.00 a month 4 years ago,300.00 now.

The difference is in the physical properties of the spark. You're comparing a kitchen match to a lightning bolt. If you don't believe the difference is relevant, how do you explain the need for High $$$$ ignition systems on race engines?

Once the fuel charge ignites its gonna burn.Early gas engines used a hot wire thrust in to the cylinder to light the charge.You can fire dynamite with a fuse or an electric cap.A racing engine is an entirely different animal.Your tractor does a lot of work at 1000 rpm.Points would suffer at 8 to 10000 rpm.A hot rod magazine ran a 39 mercury thru the quarter mile with stock and then magneto ignition,same elapsed time.

HIGH $$$$ HEI systems throw a HOT spark, that is true.

However,Pertronix Ignitor systems are a different "animal" altogether, and are pretty much limited to what you'd get out of the same igntion system with a good set of points.

There's NOTHING magic in that little module that can coax more spark out of a coil than a good set of points can. Of course, there is not the problem of the points degrading over time, making for a weaker spark.
