Im currently having the problem of my plugs constantly failling out, or as ive been told,"my spark is being blown out". Its set up on the stock dist w/ stock coil, but i do have a Jacobs ign already hooked up, just need to plug it in....My problem there is Im hearing the Jacobs is crap, ditch it and go with a MSD digital 6........Any input would help....My mods that i know of....are Forged rods, pistons, cam'd, 2000 vortecs, 33lb inj, kb afpr, kb air to air, headers, and a t3/t4 wanting to run 15psi...........thanks guys :)

also, im on the stock 2bar map.....

Stock coil,stock dist,8mm wires with heatshield socks and Autolite 23 plugs..
Seems to work fine for me the last 60k. :dunno:
What gap you running?

Re: What ignition you guys using???

unless you want the revlimiter and 2 step abilities any msd or mallory ignition will work better. something like a 6 al. the reason is that these ignitions spark about 6 times for every once the stock setup does. a blaster coil is fine. some people have preferences on the mallory or mds brand but i think they both will work fine. i've had them both. if you want the options that a digital ignition will give you the digital 6 is a good one. i ran a msd 6 with my stokes at 30 pounds of boost and a 70 and never missed a beat. with the standard you can buy modules to do other things but it gets more expensive to add the features that after and they don't work quite as well

thats what i was leaning towards getting was the msd6.....My current gap is at.020 and im still having this problem.....not right away but after i run it about 3-4 times...schitty....well, i guess ill have a jacobs ignition w/coil for sale soon... :tup:

Re: What ignition you guys using???

If your running SRP's instead of JE's then you probably are having the same problems that I had. I couldn't keep the plugs lit after several runs when using 20-22 # boost and above. Tried about every plug out there and even had NGK and the JE techs talking together to find a reason. JE's weak answer was that the SRP's weren't made for that kind of boost and that the piston design should have cut differently if they had know that we were going to run higher boost in order to fire easiler under high boost. It sounded like a standard excuse...always the customer's fault for not using them for want they never told us in the first. They did say that the JE racing piston that Les and alot of other run (versa SRP's) is designed for the higher compression (higher boost) thus easier to lite under high compression.

I was ready to go the coil per plug route when a serious drag racer/builder friend of mine suggested to do what the big compression boys do...use a hotter tourch. I ditched my msd 6 and went with a msd 7. End of story for my misses and fouled plugs. I now run .035 gaps instead of .025 and .028 gaps to try to keep them from fouling with my msd 6 box. I also can run a colder plug so I run more timing and not deto. I run cheap 103 autolite @ less than $2 per plug.

A couple of things when going this route is the you have to run the big coil that matches up with the msd 7 and you have to run the biggest, baddest wires you can find. I went through 2 sets of msd 8.5 wires in a month...actually they lasted about a weekend each. then tried a set of 11mm moroso's and they lasted about a mouth. I then took my time and made a set using moroso's 9mm ultra's and put on their sleeve system, and used heat socks (used the heat socks on the msd wires also). I now have had those wires on for 1.5 years and no more ign problems. I have been running running 28 - 30 # for most of last year and was running 30-32 # boost the last couple of weekends. I couldn't be happer with the outcome of the msd 7 box. I still run the stock dist... and timing?...I was running 28* @ 30-32# of boost, wot, yesterday on 114 octane. (I normally run 26* with 110 octane).

With a nice tail wind (20mph) I ran a 10.61 @ 132 mph on plugs that have been in most of the summer. I know it's not as fast as Maxtor's (Les's previous stroker sy) and all those 9 sec sy's, but hey, it's gett'n it for a 4,000# brick.

I did run again this weekend (slight head wind this time) and ran 10.70 at 131mph. Goes to prove that keeping all the holes lit at high boost (and sometimes a nice tail wind) will keep you mov'n!

Nothing to do with ing issues...but I did improve my 60" to 1.46 on a 50 degree day track...It felt like something had to give somewhere... and actually have some footage of my front wheels off the ground ( very slightly) and bouncing a couple of times. Did it on several runs. Nothing broke...

Nice write up :tup: ...Sounds like you are running a similar setup, I know im running Lunatti rods and im pretty sure they are JE pistons....Before i bought this Ty, ( Ry) guy was running 25lbs all day.....im thinking with going with at least the msd6, but now i might look into the msd7...... :)

Re: What ignition you guys using???

i have had two msd boxes go bad, and know a lot of other people who have had the same problem. ive got a msd dist, fresh msd cap and rotor, i made my own wires from a roll of 8.5mm msd (cheapest route and nices fit) and a msd coil. it worked fine as long as my plug gap was around twenty thousanths. I just recently bought the accell 300+ kit and put that in. thats the box and coil. that made a noticable improvement over no box and the msd box both. It is super easy to install because of the nice plug n play harness, and it is half the size of the msd or crane box. it has the rev limiter if you want it, it has the least amp draw of any of the boxes, and makes a very nice spark. Its not too expensive and i immediatly noticed a difference in throttle response and the motor was much crisper all through the revs. I would recommend it for sure...
 
Re: What ignition you guys using???

Well i jqave always ran the MSD stuff and been very happy, but only with N20 and NA motors never on a turbo or s/c set up, but the hotrer you can get the spark and a good multi spark is always a good thinkg the better off youll be.

And just in casr your interested, i have a slightly used MSD Digitial 6 for sale that has the adaptor harness for a plug and play deal on your truck. I had it installed on my Sonoma GT and a 2001 Blazer X before that. Works great and nothing wrong with it, i have an ad in the for sale section. Im asking 250 shipped for it. LMK.

Good luck with your truck. Sounds like it should be good for some low times at the track.

Re: What ignition you guys using???

what john is telling you is all true. i remember cause we all did that stuff when we were together at bowling green and i was along when we went to the speed shop and bought the wires and we helped him. the wires are about as big as my thumb and also used the sleeves. the digital 7 puts out so much spark that you need to do big wires like that. i think they could use johns ignition system to supply an electric chair for executions.. damn that thing is hot. but it solved his problems

the only problem we had that weekend is we kept getting thrown out of japanese restaurants and gettin beat in street races with his denali with 6 of us in it trying to streetrace the local guys. too much weight (mostly me... :(..) and i slowed him down. so we went and got my sy and his ty and it was funny how results changed REAL FAST in that town... :) after we brought out the toys... the only good street races we could find were between john and us. i had a great time. john took my one son in his ty. my other son took john's friend in my sy. and i got to try to keep up and watch out for cops in my fantastically fast big denali that runs 0-60 in about 12 seconds. yea right... i kept up really well...:( but my a/c worked better... shit man... i bet the locals are still talkin about the sy and ty... they got WHACKED... BAD...

hey john... how you doin? you still runnin around with that guy who we always had to drag out of the bars so we didn't get in trouble... glad to hear your ty is runnin good now. i wanna know when the pro street ty is gonna hit the roads?

Re: What ignition you guys using???

MSD digital 6, MSD billet distributor, NGK iridiums gapped at .025, 11mm moroso wires, stock coil. The NGK iridiums are the ticket!

Like Phillip said, minus the MSD distributor and 11mm moroso wires. And using a MSD 6A, NGK UR6IX Part #7348

Re: What ignition you guys using???

Would an MSD 6 be ok for a stock motor? I see that most of you have built motors I just dont want to go with something thats too big or advanced for the motor. I just bought ATR Black Beauties but havent put them in yet. anybody ever use 'em??
 
Re: What ignition you guys using???

Yes the MSD 6a or 6al or even the digitial 6 will work fine on the stock engine and will work great with the stock coil and the ATR wires.

Id go with the digital box myself, as it has alot of built in features that are real nice and it can grow with you down the road as your mods grow.

Re: What ignition you guys using???

I upgraded my MSD 6a to a digital 6 late this summer to get the 2-step feature built in but otherwise I have the stock distributor, brass cap/rotor, stock coil, and Taylor wires with Autolite 103's gapped at 0.030". I've never had a spark issue up to (and occasionally slightly past) 30psi with 24-26 deg. of timing and 112 octane.

You mentioned that you stayed witht he stock distributor? Did you stay with the stock distributor gear? Or did you upgrade it? I'm just wondering if my stock distributor and gear would be fine with my build.(See my Sig)
