Good old MSD. Some people love them, some don't. What is your concern? What are you putting it in?
 
Better than the chrome box ? Running on a mild 440 Ran a 6al on my 500 stroker and was awsome
 
I think that is the same as a 6 al without the rev limiter. 6a
 
They are good until they aren't. The older models seem to last longer compared to the newer models. Nothing new there!
 
I had a 6C on my Duster for many years. Put it on back in the late 70's and used it for almost 15 years with no issue. Later on I found a 7C and used that too.
 
Better than the new ones IMO. I have an NIB 5C somewhere I should sell. It's just a cool piece though.
 
Knock on wood..still running 6AL's after 30+ years of use.
Imho..The old MSD analog ones are probably one of the most dependable parts you can put on your car.
They start slightly better then a mopar unit..but I have done back to back runs at the strip..no performance gain.
 
Put me on the list of those who love them..
Put me on the list that despise or don't believe in all their hype for them. When I first aquired the '70 GTX RS23V0A******, 34+ yesrs ago, it had the MSD "C" style with the MOPAR 5 prong plug on one end, directly powered from the battery circuit, triggered by the MOPAR electronic distributor and the control unit mounted UNDER the battery tray. It worked OK. I inquired to MSD about replacement parts for the ECU (should it have crapped out in service). I was told, "send it back to us for repairs, we'll fix it and return it for a nominal charge plus shipping, .....Repairs were estimated at 2-3 weeks". My fix was to REMOVE ALL THE MSD STUFF and wiring including the MOPAR electronic distributor and install an origional (numbers matching) Prestolite dual point distributor (recurved), MOPAR coil and ballast resistor. All the MSD stuff was deposited in the round file, and i gave the MOPAR electronic distributor to a friend for his Chrysler 300 Hurst. The original Prestolite dual point distributor (recurved) is still in the car and performs just as well, or better the all the MSD claims....then and now......

On the RoadRunner I had the MSD box with the Mopar connector on my built wedge motor....
Re-timed it, engine ran fine but was harder to start and didn't run as well as it did with the Chrome box.
Took it off, gave to another Mopar friend and re-installed the Chrome box..

Just my $0.02.... :thumbsup:

You prefer stock... That's fine... I've run plenty of stock stuff, it's fine.. But if you like running a nasty cam that barely idles the MSD can light mixtures that are far from ideal... Stock doesn't do that very well..

As I've mentioned b4, my cam is a Crane equilivant to the MOPAR 292° w/ 0.509" lift and 1.6:1 Crane roller tipped rocker arms. The engine idles @ ~ 1200 RPM hot. I cannot remember the exact cam number but it was installed at 2° retarded. The torque range is ~ 2200 RPM to ~ 5000 RPM. I fo not race the car......just my thoughts.....

Running mine for years. All good.
 
As others have said above, I much prefer the old analog units to the current digital stuff. I've got a msd so old (from El Paso, Texas, if I remember right), it doesn't have a model number, and the serial number is etched by hand. Still works.
 
Everyone I know reports better starting with the MSD. That's going back to the "old days" units. They are all still running, I don't know of anyone running a newer one.

:lol: ....I'm in the category - tried that, didn't like it, went back to stock.
 
I'll be using a 30 year old oval track analog MSD in my Coronet just because I have it...actually I have two.

Should work fine with my points dizzy...
