Hi David,
There is one version of the MSD coil that is a direct replacement for
the LS1 coil. I'm sort of making an assumption that it is a multiple
spark coil. I can't remember right now if Lynn is using leaded fuel
either, but I think better firing of wet plugs is accurate. That's a
good thing too. :)

Lynn H has provided regular info on MSD ignition systems - am I correct in "remembering" that the MSD coils would be used in place of the GM LS-1 coils? Wasn't there an implication or experience that plugs don't foul as badly with MSD? Or was that an issue only of "starting better" if plugs get wet? Probably two different things - but would be nice to have someone report experience with MSD and 100LL fuel.
