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.
