MSD Stacker Ignition #7020...
Has anyone ever installed and used the newest MSD ignition for cars with individual coils? Summit has it for $369.00. I believe it has CARB exemption.

MSD boxes are multiple spark. Hence the name Multiple Spark Discharge.
My understanding of this is that for 20 degrees of crank rotation after the main spark multiple sparks are fired. This allows for any fuel that is not combusted from the initial spark to be burned. This in combination with the higher power spark may net a more complete burn. Will it net any real world power? Maybe not. Will it have a more effiecient burn? Maybe. Is it more powerful than the stock ignition? I don't know. It is probably more useful on a car with a truely weak ignition system.

Then I guess I just don't understand your original question.

Does the stock ignition have multiple sparks? Please enlighten me, that's what we're all here for.
