Any of you guys running it, what do you think? Is it worth getting. I got a deal on one from a buddy who used it on his LT1, but recently converted to the LTCC LS1 Coil Pack Concersion, so he no longer need the Digital 6 box. He said he would let it go for like $125. Would it be better to get that as compared to a brand new 6A box?

What were you initial impressions of the Digial 6?

Oh yeah, and hookup wise, did you get the harness from MSD to fit into the stock wiring?

 

i wouldn't use one on a stock or near stock application and i wouldn't buy a used one.

 

My setup sure won't be stock. The setup I am getting ready to throw in is in the sig. 355 w/ 227/233 cam and TFS heads, LT1 intakes... I sure hope it doesn't perform like stock.

 

im running it with the mods in the signature, and i feel a difference, nothing big but u can feel it pull a lil better up top

 

But what is your ignition setup.

 

Stock distributor, and was going w/ a MSD blaster coil and MSD 8.5" wires...

 

What is the difference between the Digital and the MSD 6A box???????

 

MSD 6A, PN 6200
The MSD 6A is the base model of the capacitive discharge multiple spark 6 Series design. Whether you have a powerful street machine, hard working truck or trick street rod, the powerful multiple sparks of the MSD 6A will ensure complete combustion. Benefits such as quicker ET’s, easier starting, reduced plug fouling, more power and even increased fuel economy can be expected with the 6A’s high energy multiple sparks.
Like all of the MSD 6 Series Ignitions, the 6A will work with virtually any vehicle as long as it has a 12-18 volt electrical system. It can be triggered using breaker points, a magnetic pickup or the output of an electronic amplifier. All necessary parts and wiring instructions are included.

Digital-6 Plus Ignition Control,
PN 6520
The all new MSD Digital-6 Plus Ignition Control embraces advanced digital technology to take performance ignitions into the future. No other digital ignition can match the power and efficiency of the all new MSD Digital-6 Plus.

MSD combines race winning experience with cutting edge technology to create the most powerful Digital Ignition available! The Digital-6 Plus is Digital Done Right!

The heart of the Digital-6 Plus Ignition is a 15 Megahertz microcontroller, the fastest of all digital ignitions. What this means is the controller analyzes up to 15,000,000 critical instructions per second! This is over three times the speed of comparable ignitions and produces the most accurate trigger signals, timing and rev limits possible.
MSD engineers have spent an endless amount of time testing the components of the Digital-6 Plus to ensure the most efficient and reliable operation. The 6 Plus produces more power with less current draw (20% less) by incorporating an IGBT coil driver that can be controlled for improved coil saturation. Also, power MOSFET technology and high frequency magnetic converters require less input current while producing more energy and voltage.
Every spark of the Digital-6 Plus ignition is packed with 135 millijoules of spark energy and up to 535 volts. When used with the MSD Blaster HVC Coil, PN 8252, a spark with over 300 milliamps burns across the plug gap for 400 microseconds. Below 3,300 rpm the Digital-6 Plus produces a series of sparks that glows in the cylinder for up to 20° of crankshaft rotation. This incredible heat ensures combustion to produce great power, quick throttle response, smooth idle and quick starts.
To prevent any chance of Electro Magnetic Interference (EMI) a filter circuit is made up of state-of-the-art magnetic suppressor components. This, combined with the more than competent microcontroller, checks and rechecks inputs many times to determine “clean” signals before making any compensations. The magnetic input also features a unique microcontrolled feedback circuit for total EMI-free operation.

That stuff is straight off the MSD website.

 

that sounds kinda high for a used 6a(you can buy a new one for 150), especially if hes a friend


EDIT: Oh yeah to stay on topic it's not a bad buy if youre sure that the box is in good condition IMO.

 

He ran it on his car for about a year w/ no problems, and then tore the car apart about a year ago. It hasn't run since, being he is building a 383 T-76 turbo setup. They retail new for like $250, so I though the half price would be worth it over a 6a.

 

I have a complete MSD setup in my car and I love it. I use the digital 6 with an 8366 dist and 8226 coil with 8.5mm superconducter wires as well. The digital 6 is good if you need to use a rev limiter in the future or plan to run supercharger or nitrous. I think its worth what he's asking. These MSD systems do exactly as they advertise them to do. However, not everyone agrees with that statement. You will find that the majority of people are pleased with MSD. I would still use MSD even if I had a stock setup.

 

I have heard good things about MSD replacing ones when they go bad too, which is making me consider the used piece even more. I know one guy who called them when his 6A went out, they said ship it back, and in 2 weeks he had a brand new one.

Any one else heard of something like this?

 

I've never run the Digital 6, but....

Back in the late 70s/early 80s, when MSD started out, my late little bro worked at RHS's store; I'd go down there sometimes at closing time to visit. They had a little demo unit with a spark gap arrangement that you could screw apart and together, and a switch you could flip to go from a std ignition to a MSD box. At the time, it was utterly amazing how much more spark came from the MSD than the stock ignition of the day; pretty effective demo really. The guys who worked there would use it to light their cigarettes to show customers how powerful it was.

They also carried Vertex magnetos, and their counter was a big all-glass thing with a metal frame. So the hot ticket was that when one of the guys would get to being a little too cool with a female customer, they would wait until he was leaning against the counter; and somebody would lay a mag against the frame and spin it, and knock the guy into the middle of next week. Well after a while everybody knew not to lean against the counter any more.

So I got my little bro to sneak one of the store butthole's cigs out of his pack when he left it laying somwhere, and draw a little pencil line down each one of them; sure enough, while we were all hanging out after the store closed, eventually the guy used the MSD thing to light his cig, and it damn near blew his lips off. The guy was ready to KILL!!!! We all laughed until it hurt.

 

LoL... That guy got

So RB... I guess from that you area saying that a MSD box is good?
