I have been thinking about getting a msd 6 plus box for the fury is this a lot better then the orange or chrome box?

I'll throw the Pertronix Ignitor III in the mix. 
I have their billet dist., built in rev limiter, multi spark through the entire rpm range........

I will say the MSD is a good ign. Now on my sons car we switched from the orange MP ECU to MSD and it ran the same et as with the MP ign. So if the ign on the car now is working good I dont think you will go faster but you will have the multi-spark ign and it helps keep the plugs clean longer. You cant go wrong with the MSD but as long as you have a good ign now you wont be going faster but may start better with the MSD multi-spark ign. My sons Dart did not as it started and ran the same but his orange box worked good. Ron

What Ron said, are you having a problem now or are you wanting to change something/spend some money (the story of my life). Or are looking for more power. I've considered the "P" III also

The mopar stock electronic ignition is fine for mild performance. I use it on both my muscle cars.
It's when you build a high compression race engine is when you need the MSD, not for a street/strip car. IMO

I can post a dyno comparison tomorrow if that will help you.
A multi spark does almost nothing on a well tuned engine. Its the ignitions other characteristics that make an MSD worth a little power.
The MSD 6 al was designed back when Mopar designed their ignition systems. There are better components available today. The good thing about the MP boxes is its cheap to carry a parts store replacement to get you home if it fails.

Points and condenser would be better than an orange box.
YMMV

I like the MSD myself. Where I noticed the biggest difference on mine was cold weather. Below 40 mine would foul a plug on start-up with an orange box and never pick it back up. With an MSD it started clean at -7.

This reminds of this day, the day of the freezer bowl. My 73 challenger with a 340 700 double pumper and stock mopar ignition was the only car that started on my street this day. It was a rusty, loud header equipped junker that sat out on the street.

i've had an MSD 6 for years which i used to replace the MP electronic upgrade on my 440 RR. keep in mind 25 years ago there were few options back then but i did notice easier starts and maybe better mileage. that said would i go with MSD if i were doing it today? Probably not. most likely choice would be to try that Rev-n-ator. i like what i've read about it, the dyno tests posted and the fact that it's plug and play for piece of mind....

Consider how you will be using the car.
For a "Daily Driver" the stock mopar electronic ignition is best only because most part stores have all you will need in stock in a pinch. IMO.
Most of the other better options don't give you an " OUT" if you should have issues on the drive to or from home. It wouldn't make sense to have a second replacement unit in your trunk and have to change it roadside.
I don't know, maybe have an old points and condenser unit handy? Not me but it IS a doable option.

I have always relied on MSD 6AL boxes because I race a stick car and needed the rev limiter. I will go with the new Firecore50 ignition box if my MSD ever fails.
I always wondered why people would run an ignition in their car that is so prone to failure that they'd never take a trip unless they had a spare box and a ballast resistor in the glove box
Personally I would go Firecore50 if I were starting from scratch

Petronix 3 is a really good unit. It looks like factory built in rev limiter works great. Got it on my 416. And almost forgot you can do away with the ballast resistor.

I have had all kind of different problems with the orange ECU's, but I still run one on my GTX 
On a street car you want vacuum advance, on the strip you don't. That's the base line. I don't think there are any bad brands out there, except maybe for the Chinese MSD copies.
Right now I'm building a crank trigger ignition without mechanical distributor for a 440. I believe there are lots of hidden ponies in the ignition. Think all the way from crank to the plugs... Have you seen a steady timing marker on an old V8?
I will try to run it on a chassis dyno before and after to get proved figures!

i wasn't really thinking i would do it for,More h.p. i was just wondering if they are more reliable i think my 69 super bee clone im gonna build will have a msd.My fury will probably just get another box right now i have a blue one from oreillys.

Yep sure have.... Ever since I put the Firecore distributor in it!!

here is what i am running

a little pricy but it bolts in like a stock unit. plus a rev limiter

The MSD's advantage if there is one will be more pronounced at low engine speed under 3000 rpm because that is the range that it multi strikes. Over 3K it goes to single strike.
At idle speed the multi strike hits it several times over 20 crank degrees so if it doesn't light it the first time it gets a few shots at it. This helps get a cleaner idle on engines that have cams with a lot of overlap.

he is indeed! but i think he fixes them because it's too hard to get stuff in his country. it's easier to fix what you have or found. i also believe when he wrote his thread about doing that that he determined heat was the number one issue with the internal components. now why do they get too hot? you'd have to ask the crowd who runs them with no ballast.

Forgot about that crowd.
I've still yet to have a Mopar ECU crap out on me. I'm patiently waiting and it's getting a bit frustrating to be perfectly frank.

I had a mopar ECU go bad in 1976, my car sat broke down for 4 or more months until my uncle helped me figure it out.
Then I don't remember another going out on me since.
I have like 6 or more ECUs from cars I parted out. I found that a OEM one from the early 70s runs better than the chrome one I bought in the 2000s
