MSD ignition box

Redneck86 · Apr 1, 2008

I was thinkin about addin a MSD ignition box to my truck. MSD says there suppose to improve power, drivability, idle quality and warm up the engine faster. I was wonderin which one would be best for me, i was leanin towards the MSD 5 box. Im gonna run the stock Duraspark distributor, Edelbrock 750 Performer carb, ACCEL plugs and wires, and MSD cap/rotor and MSD Blaster 2 coil and possibly a Edelbrock Performer-Plus cam/lifter set. So i was thinkin the MSD 5 box would be a good choice, but i was wondering if there would be a better one for me. And some you know my plans are to sell the truck, but i still have to hang on to it for about another 6-8 months...so ill get *my* use out of anything i put on it.

i would suggest MSD 6 or MSD 6al (with rev limiter) and rather then running the blaster coil run the e style coil they put our more voltage then the blaster does

6 al box works great for me, it does burn up regular plugs fast, found autolite raceing plugs hold up okay

6A works great for me as well, had them on multiple rides now and had had no issues.

I looked at the MSD 6A box, it cost alot more then the MSD 5 box, i was wondering if the MSD 5 box would work pretty much the same for me, or if yall really know if the 6A is that much better. Also when you hook one up does it replace the stock ingition box, or work off of it?

It is an add on to your existing spark box. Yours should be EFI correct? If so, it uses the TFI style coil and there is a harness that connects it directly into the existing harness. Real simple install. I havent looked at the 5 box so I have no input on it, sorry.

Mine has the 351W which was still carburated for 86. And the MSD 5 box is alot like the 6A box, i think that the 6A is just a newer version. I have seen that the 6A box is a little better but if i can run the 5 box and still have it do pretty much the same...

Heres some links to Summit on the MSD boxes

I have them on all my trucks except the diesel for obvious reasons . They do work very well I use the timing computer as well whick alows you to lock out the rotor advance weights and adjust the timing curve electronically . I would get a 6 box with that you can use anything you want with it . The offroad boxes are nice but what they dont tell you there is that they cannot be repaird because they are encased in epoxy for vibration resistance . I did have one go bad a long time ago and that was the case it was just out of warranty so I thought I was screwed when I found out that they werent repairable but the tech put me through to someone there and they actually sent me a new offroad box so that was cool but Id never spend the money on one again only the 6 or the 6T . You also need to pay attention to the plug wires after install the spark is very strong and if it gets you trust me you will never forget what it feels like . My 2 cents

So if i run the MSD 6A box i dont need my distrubutor vacuum advance any more?

BLADE262US · Apr 3, 2008

No its a seperate unit that lets you lock out the rotor works with the MSD box . The adjustable one is part number 8981 . You can look it up at summit or jegs . Works very well been running one for yrs .

Thats a little steep on price, i wasnt lookin the drop that much in my ignition. Have you ever run or heard anything about the MSD 5 box? Id like to run that one if ill get the same from it with what i plan to run. Everyting i plan to run is up listed in the top post, except the Edelbrock Performer intake i forgot to list.

BLADE262US · Apr 3, 2008

Its up to you what you buy but if it were me I would not buy the 5 box . The 6A is the base for all of the add ons you can add a soft touch rev control , timing computer whatever you want and the price isnt much more than a 5 . Heres a link to the comparison chart just click on the 5 then the 6 its your choice

Thanks man that what i needed, looks like the 6A box. It says thats the one for my application, and is gonna do what i want.

BLADE262US · Apr 4, 2008

Yeah youll be happy with that and if the cost is whats holding you back check ebay . On the home page type in MSD in the search theres always pages of MSD stuff I once bought 2 MSD 6T boxes which have the pigtail for the soft touch rev control built right in and a soft touch for $200 . Ebay is always good for a deal just keep looking .

Nah the price didn bother me, its only an $80 differance. I was just thinkin it would have been nice to save that 80 if i could and buy somethin else with it. But this 6A box is gonna do exactly what im lookin for it to do.

2NDTOUR89 · Apr 7, 2008

If you are interested, I can get you one of these for $10.00 cheaper than Summit through my work. $175.00.

Redneck86 · Apr 7, 2008

When i got the money to buy it ill let you know

2NDTOUR89 · Apr 8, 2008

Let me know. I sell parts for a living and can get good deals on performance parts as well.
