MSD ignition componants part numbers.

[99Yuk]

Ok, I feel kinda foolish for asking this but.....

If a fella wanted to replace his entire ignition system with MSD parts, what parts would he need?
I've already bought red MSD 9mm plug wires, but what about the rest?

I found a deal on a 6AL box on kijiji, but a google search showed many different versions of this box, and I got confused by the options. I can't even determine if I would need a 6AL.

I would be looking for better performance, don't care about mpg.

What MSD part numbers would be used to replace everything?

This is what I plan on replacing my stock parts, when the funds allow, hah.

6A box (if someone knows of a newer model please inform me, hah)

Hey, thanks for the links! They are getting me started. I hear ya on the funds issue. Thank goodness my credit card statements don't go home. My wife would shoot me!

I made a mistake, my wires are not 9mm, they are 8.5mm. The same ones as these..., just didn't buy them from Jegs. I bought from partssource, who I think got them from Dix Performance from Alberta?

And, which box should I buy?
6A from summit Racing - with no rev limiter?
6AL from Kijiji - with no rev limiter?
6AL-2 from Kijiji - with dialed in rev limiter?
I have no idea what the difference is, other than the 6AL-2 box has higher specs?

And what does this do for me? And is there a MSD equivelent?
VORTEC DYNA-MODULE
Improve the performance of your Vortec by installing our high dwell Dyna-Module!
Dwell within the module controls a coils saturation time, which is the time needed by the
coil to produce a spark. The dwell in our Dyna-Module has been increased electronically
to provide the coil with additional saturation time. The result is a more intense and longer
duration spark in the combustion chamber that will improve throttle response and low end
power! Installation is easy as the Dyna-Module mounts in the original factory location
with no modifications.
Part# 000666 (Vortec Dyna Mod) $95.00


EDIT: Been reading, the MSD 6A boxes would not require the dyna-module. I think...

So, spring is comming. Time to start thinking about upgrading the Yukon some more.
I've spent all winter googling MSD parts, and this is what I've been buying.

I just received the MSD Blaster SS coil. Part# 8207. Link HERE.
And the MSD distributor cap and rotor arrived today. This threw me for a loop and I lost a $20 bet. I couldn't find a MSD cap on the MSD webpages and on Summit Racing, so I said it wasn't to be found. Technically I was right, and so were they. It comes as a cap and rotor kit.
The MSD Vortec cap and rotor kit is Part# 8017. Link HERE.

I've also ordered the new MSD Digital 6AL. Part#6425. Link HERE. It should be here within two weeks.


Hopefully this might help anyone else looking to buy an all MSD ignition.

That is a pretty good setup. I had a very similar setup on my 94 Z28. Made a noticeable difference in that car.

Thanks. I'm hoping that this will make some sort of difference as well.
If I'm very lucky, maybe even better mpg due to the better/longer fuel burn.

 

[BattelWagun]

Please let us know! I was thinking of a new coil and distributor.

 

[99Yuk]

So, I have this setup installed now for a few weeks.
Well worth it!
Kicked my truck in the ass and said 'get up and go!'

BUT, It's developed a bad miss at 1500rpm. Scanner misfire data shows all cyls misfiring. Pretty sure it's electrical.

So far, I've bypassed the MSD 6A box and it got worse. Box is ok then.

I researched spark plugs and found out that the truck likes 0.60" gap, but MSD likes 040" gap and one degree colder. OK. Regular AC delco spark plug part number for our truck is C43T. I ordered up and installed C42T and gapped to 040". Truck runs a bit smoother but still misfires.

Next up is repleacing the brand new MSD cap and rotor with AC Delco to see if the misfire goes away.
I'll keep you all posted on what happens!

I posted in your other thread but forgot to mention that I have never seen or heard of msd recommending a specific gap it has always been .005 to .010 bigger then factory gap but never more then .060 for our given compression ratio. Stick with the msd cap/rotor. And use plain copper core plugs as the box has trouble reading electrical feedback with other types. Any good hellicaly wound wires are good but no solid core wires. The stock gm's can work if you don't msd wires but eventually the wire will break down electrically.

 

[992dr]

Huh, thats wierd you got a miss. Whats funny is when I hooked up my box (6A) it didnt get any spark at all. I bypassed the box and it sparks right up and runs great. Now, the box was modified so you would not have to use a harness. I'm not sure if that has something to do with OR if its the ACDelco Platnium plugs. I never knew platinum plugs could cause issues.
I have the box, coil, wires, cap and rotor. While my Hoe is down, I plan on going over this so everything works together.

 

[SunlitComet]

A complete msd setup will put out enough energy that it will just eat up the platinum plating. Copper cores hold better and allow the box to read the electrical feedback more effectively.

I have the MSD 8.5mm wires.
As for the gap, I just googled MSD 350 gap, and got my first hit from an MSD engineer HERE, and guy talk HERE. They pretty much say to gap at 0.40".
I think I'll take the MSD guys advice about gap and temp range. Anywho, it can't hurt none. And I kept my old plugs just in case these ones didn't work out for me.


As for the miss, the guys at our shop found it. It was the MSD cap and rotor. Bad from the factory. Didn't make it a full month before it burnt up bad. I took pics, but ran out of storage space to put them up. The guys put in new AC Delco and she runs like a top now.

I would like to think that the MSD stuff in general is ok and I just got a bad one, but IDK.

I'm just glad its all worked out! If anyone is on the fence about the MSD box, I say go for it!

 

[SunlitComet]

And both seem to refer to carbed or tbi 350's or more specifically not in reference to vortecs but hey, what floats your boat. Just pick up the msd phoe tell them what you have and what the factory plug specs are and let them speak for their product themselves. Still seem like a fallback in performance for the vortecs when you go from factory .060 to a .040 when more exposed spark contributes to a more complete burn. MSD stuff is always good but will take some tweaking and visual inspection of cap/ rotor and plugs to perfect it performance.

 

[99Yuk]

Meh, we'll see.

The plugs only cost $20. If they foul, then they foul. Can't hurt to try? Then I can post up here the results so others won't make the same mistakes that I do. IDK.

 

[99Yuk]

UPDATE: SunlitComet was right. These plugs are shit. I've been reading up on spark plugs HERE.
Short quote...

A rule of thumb is, one heat range colder per modification or one heat range colder for every 75–100hp you increase.

Well, these colder and smaller gapped plugs have fouled, and it idles rough. I'm not making an extra 75-100hp, so I've got an appointment next Tuesday to get some maintenance done on my truck and it's getting THESE again.

cheap ass NGK coppers gapped out until I got a misfire then back in .005 is what I ran in my toys for years.
ran same plugs till they got some wear on them then filled the ground strap square again, along with squaring up the electrode. and ran them till they corroded up.
then it was time for a change..

 

[SunlitComet]

99YUK since you have the complete msd setup use Autolite 605 copper cores. They wear faster but get the most out of the msd box. They are not colder or hotter. They are just a non-platinum stock plug for us.

 

[99Yuk]

Update: Well the new plugs are in and the truck idles smooth as glass now.

I'm all for science experiments, so I don't consider this one as a failure, as others may learn from it.

 

[SunlitComet]

Which plugs are those?

 

[99Yuk]

THESE...

I know you don't like em, but they are coppercore... And they are AC Delco... And that's what I used for the first 90k kms(56k miles) on the crate motor... And I'm stubborn...
