I started seraching summit and found this and was wondering if anyone has tried this, what do you guys think of it over converting to HEI and using Pertronix stuff?

I was thinking of just keeping points and upgrading the coil to a pertronix unit.

I am getting my engine rebuilt and would like to improve power and mpgs wherever possible.

It appears to be netiher HEI nor CDI, both of which being about the only reasons one would drop $400+ into an ignition system, in my opinion. Furthermore, both of those systems are better suited for high-performance and racing vehicles, not to a stock 4cyl LUV. There's no way a more powerful spark is going to make a $400 difference in a low-displacement engine like that - which is not to say that getting rid of your points shouldn't be a priority! I think that switching to a touchless ignition timing platform is hands-down the easiest way to add a few MPG.

The Mallory distributor you linked to seems to be a fancier version of Pertronix's points replacement kit, but not much more. No additional electrical charge provided. It's just an optical solution to the 'points problem'.

To clarify:
Points are a mechanical means of determining when to send the spark. Parts touch, pieces wear out over time, and things fall out of calibration.

Mallory uses optical input, a visual means of determining when to send the spark. An eye is trained on a rotating reference wheel, and it knows precisely when the wheel is at the correct position, similar to ABS systems

Pertronix is magnetic, and has an electromagnetic means of determining when to send the spark. Instead of an eye, it's a little magnetic sensor, and instead of a reference wheel, a magnet. Rotation of the magnet tells the sensor when it is in the correct position. While neither optics or magnetics have parts that touch eachother, a rotating magnetic field is more robust, reliable, and fail-proof any day of the week. Can you imagine trying to figure out why your truck won't start, only to find that your optical sensor is dirty, and hence, blind?

I figured it was something like that, thanks for clarifying.

I searched ignition stuff on summit by make and year and I see they have the cylindrical style coils for the points system and a newer HEI style coils too.

From what I've read on here I would need a distributor out of an 85 pup to use HEI and put the Pertronix D3000 coil onto?

Actually it is better than an HEI...no points.It basically uses a hall effect system.Pretty accurate timing.

So is that all I would need?

The stock 85 pup dist. and the Pertronix D3000 or am I missing something?

You shouldnt even need to get an 83 dizzy, if you do then you wouldnt need the Petronix because the 83 is already without points. Just keep your current dizzy and find the right Petronix kit for your truck. There is a threed here somewhere the spells it all out. After being left on side of the road a few times I tossed the points and threw in the Petronix and life was good. I also added an MSD box to get rid of higher RPM misses. Im over seas right now or id go into garage to get ya more info. Good luck.

to clear up a bit of confusion
i am the one who said use the 85 pup dizzy, but i am using one instead of the pertronix setup not together with one.. either one will work just fine for you see which you can find cheaper and go with it they will both yield similar results. right now i think pertronix is cheaper. i got my pup distributor on a closeout sale from rockauto, search ebay and see what comes up, if you ballin on a tight budget maybe check a nearby junkyard for 1.9l isuzu pups to pull a dizzy from. it looks very similar to the stock one from outside but once you pull the cap the inside looks very different. the center of the distributor has flat sides and round corners that open and close the points in a cam style mechanism, the pup unit is more or less a square with a narrow vertical rectangle on each corner which i am assuming are the magnets for the sensor, no contact is made between the rotating and stationary parts

the pertronix unit will drop into your original distributor in place of its current points system, it should give you a couple mpg as well as a slight boost in power and more consistant spark at higher rpm

if you were to go with the pup distributor it is a drop in unit you pull out the old one, drop in the new one, check and set the timing and go. the only issue i had with mine was the wiring because my dad and i had a disagreement over where the wires went.. long story short i won :lol: its only 2 wires to + and - on coil. i think pertronix is the same way wiring wise

if anyone wants a picture of what the inside of the correct pup dizzy looks like let me know and i will go pop the cap off mine and post a few up. i think i have the original in the garage somewhere for comparison.

Thanks for clearing that up!

I think right now it would be easier to go with Pertronix components and that MSD box, if I could just get the part numbers...

I tried searching for this info on here but just when I thought I found what I needed and started taking down parts numbers I saw the thread was about a SBC and not the stock Isuzu motor lol.

I kept searching and the only part numbers I found here were for 72-75 LUVs, another person said they don't even make them for 76-79?

When I search for the parts on Summit by make and model all I get for Pertronix is HEI components...

Sounds like I need to contact them directly?

I did find this though:

I didn't read all through this, but I had a Mallory dual points dist. that had a Unillite conversion on it. The Unilite utilizes an actual light inside the dist. I found for myself and others told me, that light is unreliable. It burns out, and you are dead on the road.
I have had very good luck with the Pertronix conversion, and newer LUV/Isuzu electronic ignition.

Thanks for the tip rondog, a lot of things sounds really good on paper when you see the technical specs lol.

Ok I found this in the Pertronix 2012 catalog:

1976-80 4 (cylinder) LUV Pickup 79 Nippondenso (distributor type) 1643 (part number for ignitor) 91643 (part number for ignitor II)

So i got one part located, I still need the Flamethrower coil and the MSD module part numbers...

I found the Ignitor I and the coil:

http://pertronix.shptron.com/products/productdetail/Ignitor+kit+for+Chevy+Luv+Pickup+Trucks+with+a++Nippondenso+Dist/part_number=1643/591.0.1.1.26484.26485.0.0.0?pp=8&sort_selection=partnum&

[url]http://pertronix.shptron.com/products/productdetail/45%2C000+VOLT+FLAME-THROWER+II+%280.6+OHM%29+BLACK/part_number=45011/591.0.1.1.0.0.0.0.0?
[/url]

Does anyone know where to get the Ignitor II kit?

As far as the MSD box, do you (or would you) use the one with the rev limiter or without?
