What Distributor

Looking to update my ingnition looking at the pertronixs plug and play. First my motor is a 429scj with dura spark and old Jacobs ingnition box and coil and over the years because of the 11:1 CR it works best with no vacuum adv. hooked up dont if this is because I don't know what I'm doing or what but when you hook vacuum up it Predetonates. My question is if I buy new distributor what to buy they have vacuum with mechanical adv then they have vacuum adv. and the just all mechanical. I call the tech guy at pertronix and he's said my motor didn't come with vacuum adv. just dual points well I searched that and from I could find is it did come with dual points and vacuum adv. he Suggested the all mechanical one I don't care about fule mileage and buy the way I mix 93 octane no Ethanol with 112 octane to get 96 octane. Oh buy the way the I'm looking at is flame thrower 3 and the guy said it fires twice each time to stop Predetonation any help would be great

Looks like your question was answered last year ..Sept 26 2012.

You must be able to see into the future being it is only Aug 22, 2013.  

Time traveling Okie.  

I can't see next week. And it been almost a year ill take last years post it I could find it. I can remember some of it adjustablity of after marker dizy but not the vacuum adv. part or mech.

I'm sure Dave will show his internet prowess, and provide you with a link.  

I'm sure he found out I posted a year ago

Yeah sorry , it was 2012 . I think the self contained unit was recommended .

Yea I just found out about pertronix and they are 100 dollars cheaper than msd and wondered if any one had used them and if they were any good

I would send the dist. to Scotty at RHP and have him set it up for your engine and then throw an MSD box at it if needed. They say the Dura-spark is good for up to 700 hp. FYI your SCJ came with a DUAL diaphragm vacuum advance. It had 2 hoses hooked to it. Never had a problem with mine.

Funny you said that I just talked to him yesterday and that's what I'm doing. And after reading his Article I understand the whole thing but feel better letting him set it up and ill tune it in on the road up hill and under a load thank for the Advice it's what I need and not some 300 dollar bubble gum machine for a distributor

I have seen many people try and save money and go to pertronix and every one has had the same results. junk so they have to either get it fixed or trash it, get an MSD and be done...
