I had three ignition modules go out. I decided to try the msd digital ignition and it worked! I almost went old school...switching over to points. I was that close to switching...
You're not alone! The current crop of HEI modules is really disappointing. This represents a good intermediate step between what should be a good replacement and a CD ignition or other similar piece. The biggest advantage here is the simplicity. No extra wiring is required, and it just works.
I was having the issue in my gmc typhoon. I have went through about 10 icm. I'm currently getting a maxxecu conversion on my typhoon and we're going with a holley dual sync distributor to eliminate this issue once and for all. Also getting a complete rewire of the truck
MSD module update. Well it finally happened, the DREAM CRUISE Curse finally got me again. A week or so after the cruise, on and off every few years, something electrical would fail on my car. It's been a while but my MSD module finally quit. I went to start it up no dice. I had a second one in my road kit and I installed it and boom up and running. I purchased both about a year after they were introduced, that had to be mid 90's I think, and many thousands of street, highway, and strip miles. I have built my own engine run stand, and I am going to test the stock type modules, I have, but I am also going to got back to a 6a type of box and move the electronics inside and out of the heat. Thanks for reading.
I have has 2 MSD modules, I purchased them about 1 and 2 years after they were introduced. They both have been in many different engines, with many many miles and passes down the strip. They work with out a hitch. I have done several back to back tests over the years, between stock modules, MSD module, and my MSD-6AL. The MSD module is on average .011 faster than stock, and within .002/.003 of my 6AL. I installed another engine a while back and kept the module, I haven't put the 6AL back in, on my street cars.
Those are the gains I'd expect from the MSD module. I've never tried, mostly because an original would die and get replaced nowhere near a drag strip. They're a good module that has been trouble free in that Monte Carlo.
@@SnowFamilyRacing My MAN...that's the ticket!!! I guess I should look at other Ignition modules, so my spark isn't in one basket. but the spark basket is working. Maybe other will chime in on what works good for them.
Had 1 and will not own another, blew the coil apart during a 4.5hr car drive (i drove locally never had a problem), could never get the rev limiter to work. The coil ordeal cost me a tow bill and issues at 9:00 pm. If you run one, i recommend keeping a coil, a good stock module and harness in the car as back up. I had to round this up on the road next day. Granted this was when msd was msd, maybe things got better
Honestly, this is the first catastrophic failure of this that I've heard. I've had literally hundreds of drag strip passes and many street miles with one of these.
The MSD is made in China. Do what the rest of us old timers do and stick with one authentic original "lead based" GM module for the HEI and one for the glove box. It sucks, I only watched this for info on the rev limiter but I guess that was to much work for this guy...
Not everyone has access to a dwindling stack of NOS original modules. The sad fact is that just about everything, especially electronic in naturen is made overseas. I didn't hook up the Rev limiter for 2 reasons, I was under a time crunch, and it wasn't going to be needed on this car. It's not my car, and it never sees any real RPM unless I'm the one driving it. It's done at around 4500, and it'll hit valve float before it goes high enough to hurt anything. The instructions are pretty clear about how to set it up.
The MSD module has been absolutely trouble-free in that Monte Carlo since I put it in. I'm finding that Napa is a better source for OE style electrical components, but that's no guarantee they'll live long. I've had new Napa components fail far too early. The MSD is a great choice and definitely worth the money and peace of mind to never mess with it again.
Bro I gotta tell ya, so I got an old squarebody Chevy, ‘85, and it’s just missing a little something and I’m not big on understanding the whole thing about what I would call upgraded ignitions so I punched this up and it was great, so I’m gonna try this out, so thanks for doing this
I totally understand! There's a lot of misinformation around upgrades, my intent is to show the best bang for the buck, what can be done, and what makes sense. I've played with stock stuff, through my MSD ignition boxes and there is definitely a place for each one. Quick word of caution, with the '85 you will want to know if you have the computer controlled ignition and carburetor. If you do, this part will not do any good since it's not compatible with the computer controlled stuff. I think '85 may be one of the last years of the non-computer stuff for GM trucks, don't quote me on that year I'm working from memory. Best of luck with the squarebody! I'm a fan of the '80's GM stuff!
My 383 Stroker has a misfire whether on primaries or secondaries that’s really annoying. I’ve eliminated fuel or compression issues and don’t to bother you with everything I’ve done to get me to this point. It has an Accel distributor and brand new HEI rotor, cap and coil, new plugs and plug wires. Is it time to try this MSD module ?
Is it consistent on missing the same cylinder? If it's consistent then it could be something like a mag pick up. There's a chance that the module could be to blame. Realistically, I'd be looking at swapping distributors just to see what happens at this point.
I just purchase an msd 8401 coil cap with the spark plug looking device on it to replace my gm oldsmobile hei distributor's internal coil to an external 12 volt oil filled coil.I got stuck a few times out of no where.One thing about my 1980 oldsmobile delta 88 is, when it runs it runs.But once in a blue moon the car 's engine just quits. I read where 99% of the time the epoxy layered coil gradually from heat dissolves causing the layer of winding separated by the epoxy to touch causing more resistance in the coil slowly killing the ignition module.So if you change the module and not the coil as well , if the coil was what destroyed the module in the first place ,why wouldn't it destroy a new replacement module in minutes.Especially if the coil is at that stage for the module to burn out.Reguardles of any heat sink gel under the module. I heard a lot of people have done this with no problems .So l'm giving it a try.And looking at your modification as perhaps if needed the next step.Damnskippy!
That's probably a cost effective way to get a project running. MSD has their street fire line, which is more budget friendly. I can't speak to the module quality as it's not the module used in this video.
Stock cam - .350 -.400 lift, 200 - 220 duration at .050. 1/2 cam - .400.500, 220 - 230. 3/4 cam - .500 - .600, 230 - 240. Full cam .600+ .240+. It's old school back in the day. Today's cams are way more detailed.@@SnowFamilyRacing
By the way...make sure you use the low resistance rotor button. If your car sees regular street or highway duty, the stock rotor button WILL melt the distributor cap.
Have you seen videos of guys using Progression Ignition? Looks like a cool idea, although I've seen 2 fairly big UA-camrs have the coil fail, but apparently the company sourced them from someone else.
I have heard of them, I've visited their website, but I have not watched any videos on it. It looks like a good idea, I'm genuinely curious about how well they hold up long term. I'm currently in a phase of if it's not broke, I don't need to fix it. My El Camino currently has the timing locked out at 36 degrees, and my everything is running fine, so I don't have a big reason to make a switch.
Before I swapped to a MSD box in my El Camino, I ran the MSD module and it performed great. I won a lot of events and a couple track championships with that ignition. After 2 failures in a week, I put that in that Monte, which belongs to my mom, and it's been solid ever since.
That's one of my goals, to bring this information to you, and to my audience in a way that's easy to understand. I also want to keep this info alive. That way, we can keep these cars alive! I'm 36, I learned from my dad and my Auto Shop teacher, who was a dealer tech in the 80's. I have info and a way to get it out in the world where it can be found.
@@SnowFamilyRacing No luck for me today. Monte still stalls in drive or reverse. Starter makes noise as well. I put a AC delco Hei in there. No dice. Could it be the whole dang shaft being fowled?
Still going and getting driven several times each week. I was confident enough to put it in my mom's car, and it hasn't let her down! It's been perfectly reliable.
You would have gained 12 degrees of timing at 6000 rpm if you didn't reset timing over the old OEM module, (dunno about the 602 module) no latency with the MSD. Wish they would explain that in their sales tech info.
That honestly does not make any sense based on my experience with the MSD module compared to other OE modules. The difference comes in the mechanical advance limitation of the HEI distributor. Some of the MSD HEI distributors allow for more mechanical advance to achieve the 32-ish degree total timing while maintaining a sane initial timing number.
Fun fact... Bruce is a good friend of mine and has appeared on my channel. Now, the module he's testing is not what I went from and did not notice a significant change in total timing from what was there to what is there.
@@SnowFamilyRacing Good to know. I've been looking for a good module, I do like the rev limiter feature on the MSD 83647, but they're expensive down here.
One has retired mechanic cheap or bad spark plug wires for burnout a module. The MSG mop module is a good choice, it has rev limiter adjustments to it.
That MSD module needs some conformal coating, a Common coating to protect from environmental elements, missing that, is is considered sub standard.....Is it there or no ???

Those pickup coil wires were pretty common for breakage from the vacuum advance constantly working the wires back and forth.

Just added the msd coil yesterday to my sbc. I should have swapped the module out while I had it all apart 😂

No need. The module would get removed and the box would use the magnetic pickup in the distributor.

Good point, especially with a higher powered coil. MSD does have some guidance on which button to use in what application.
