The GMC CCKW

Anyone had the electronic ignition conversion on their CCKW, I'm thinking of installing one on mine to save on distributor maintenance.
What do you think??

I have electronic ignition on my 352, although it is not the type you mention.

Overall I think it is a worth while addition, but the purists differ. This topic has been discussed recently, try searching this forum and HMVF.

I don't drive my truck enough to find that the distributor is a real maintance problem. I have to suppose if the truck is driven regularly, then setting the pints and putting in new condensers could run into a bit of a problem.

Hi,

I have an electronic ignition system in my 6 volt CCKW. It works wonderfully. The engine runs better, better fuel mileage (around 8 mph),
more power and runs cleaner. I run a 40,000 volt coil (looks like the originial but much hotter). This hotter coil allows one to increase the spark plug gap to .031 for more power. The distributor is stock with the exception of two wires coming out of it instead of only one.

I would be most interested in your sit up Capt Lee P mine is still 6 volt .Can you give some information on where you get it and how much $$

Thanks for the feedback,whilst on the subject is it worth the change from 6v to 12v or shall I stay 6v.I know 6v will give it that authentic feel but how about reliability??.
Any suggestions?

FYI...

This issue has been discussed in depth on some of the previous board posts.

There is also an extensive tech tip on the main website, written by our own Dr. Deuce, about converting over to 12 Volt. Great info.

I have converted all my driving rigs to 12 volt. They are easier to jump start that way.

.........and finding a 6 volt fridge is Sooo difficult!

I think i missed something

I was endorsing Weasle_Nuts comments. To my mind 12 volt is a Good thing ! AND you can run a ready available camping fridge! so it doubly gooder!

Hi:

I have Petronix Ignitor, part #1167N6, for my electronic ignition and Pertonix Igniter 40,000 volt Coil, part #40011 1.5 ohm, in my 6 volt CCKW. I purchased them through my local NAPA Auto Parts store in Santa Rosa, CA. The wholesale costs were $73 for the ignition and $32 for the coil.

I changed the spark plug gap to .031 and increased the engine's power, its start ability and most of all its fuel economy (from 5.5 to 8 mpg). I have also changed the valve sizes in the head to 350 chevy for both the intake and exhaust, and modifed the air cleaner to a K&N dry filter (removing the interior guts).

Hope this helps.

P.s. My truck is a driver - I have over 15,000 on her in 5 years.

Thanks a lot Capt lee p : I think for now i'm going to look in to getting the coil { i just did a tune up } a hotter spark cant do anything but help, i will definitely keep this information !
