Help me pick a distributor
 

I don't know which one I need. I am going with MSD but wasn't sure if I should get mechanical advance or vacuum.

I am building a 468 ci motor for my truck. This truck is going to just be a weekend type toy. Not a daily driver. I am going with a Comp Cams XE274H cam. If is fairly choppy so I didn't know if a vacuum advance would be right for me.

I found a 6AL Ignition box and an MSD pro-billet distributor with mech advance for a pretty good price. I started to jump on them but I thought I better ask you guys first. Thanks for the help guys!!!

Imho this is all I would use no spark boxes needed.

Pertronix igniter III has the Rev limiter and the multi spark (through the entire RPM range) built into the distributor cap all for about $230. I love mine.

So should I stick with vacuum advance for something I am driving on the street?

Re: Help me pick a distributor
 

The distributor will have both vacuum and mechanical advance . You need mechanical advance unless you plan on running a retard box and a bunch of other electronics. Any distributor will have mechanical advance.

OK, then should I run a mech/vacuum advance or mechanical only.

Run both the vac advance will help clean things up at cruise rpm

Anyone else know anything about these. They look pretty good.

I'm probably not much help but I went with a msd 6al box and msd pro billet distributor on my mild 496. I havn't ran this set-up yet as I am still in the build process.

Wanted to bump this again to see if anyone had any experience with the street/strip version of this DUI distributor.

Re: Help me pick a distributor
 

I have not read anything bad about DUI dist. In fact, i have seen them used by a lot of Engine builders, David Vizzard as one. He swares by them. But, no rev limiter or multi spark, just a bigger spark.

Re: Help me pick a distributor
 

You can order a built in rev limiter for them. What is multispark?

Built in as in non adjustable? Its fine. A multi spark means you have up to 3 sparks on each cylinder per stroke. The MSD series has 3 up to 3000rpm's. The Pertronix has 2-3 depending on rpm through the entire rpm range. This creates a much better/efficient burn which in turn makes more power.

Is this the one you have?

I am assuming it has a place to hook up a tach? How do you adjust the rev-limiter? Any special plug wires or plugs I should run with it? What is a Hall Effect trigger style as oppose to magnetic?

Re: Help me pick a distributor
 

I did not get the HEI one. I got the one with the points box. It does have a tach hook up. Adjusting it is easy. Go to Pertronix.com and watch their video on the Igniter III. Hall Effect Trigger/sensor is a different way of the spark being ignited or for the spark to be sent because the rotation of the crank.

Thanks for the advice Ripdog28, I think I will give the Pertronix a try. It sound pretty good to me and I like the price. I just read through your build thread. I like your truck man. I hope mine is making somewhere close to as much power as yours when I get it together.

Thanks for the compliment, Good luck with the rest of your build. Hope your not disappointed in the dist.
