Stock Electronic Ignition or MSD 6AL ?

I have been using MSD for over 10 years. It has once refused to start, a MSD 6a which was 1 year old. Shipped it back under warranty and MSD said it was just fine ?? Well it worked good for 7 more years. Had no rev. limter thou.

So I got a MSD 7al, its been working even better than the old 6 box. Motor idles good-but rough-when cold, in gear, no choke, Holley 750 with the proform main body, HP metering blocks. With the 6 box it would stall a few times till after it was warmed up-2-3 mins.

As for the spark boxes being for a Ford, Chevy, etc. So what. It could care less. You rewire it to the battery, use the old 12 volt on-off "run, crank" wires and fire it with a Mopar dist, or aftermarket dist. Makes no difference at all what the name on the car is.

Now with MSD stuff, you do need top notch spark plug wires, dist cap-all brass inside and matching rotor. MSD sparks are stronger than stock and will misfire easier, it will leak to ground from a weak spark plug wire or crossfire in the dist cap. I use Accel cap and rotor but others-which have brass inside is good as well.

PS, Mopar even had its name on MSD stuff a few years ago. Summit still has the 6 boxes left, but the 7al have been sold out long ago. They are painted black and say Mopar right on it, for you Mopar freaks :farao:
