The MSD 6A or 6AL are a very good product
MSD stands for multi spark discharge
There are similar products marketed by Jacobs, Crane cams, Holley, Accel and so on
They are all very similar in operation
You will get more power, smother idle, better milage
Only problem......
The boxes as any electronic device, have a limited life span, that means that its very likley that it will leave you in the middle of nowhere with no spark, make sure when you wire it, leave a provision for a quick way to wire it back to stock
If you search in the MSD web site, you will find a setup of 2 boxes with a switch, thats the setup yhat most drag racers run, that way if one box fails, you can manualy switch to the second one, with a flick of a switch.....very handy in a middle of a run, and it happens all the time
Summit or PAW have the best prices on them
Now you going to ask.....
Yossi, do you run one on your truck?
No I dont, I burned about 5-6 of them over the years
I ran MSD 6A and the crane units too
After a while, at $160 a pop.....I got tired of replacing them
on the other hand, many people I know had them on their cars for years with no problems........So maybe its just my luck
Have fun!
