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.

Subject: [FlyRotary] Re: LS1 Coil Failures
This isn't in response to any other comments on the issue, but I wanted
to mention again that there is a replacement LS-1 coil that has a heat
sink fin on the back. This should provide lower internal temperatures
for the electronic module. It is the AC Delco D585 coil, GM p/n
10457730. I have my coils mounted on top of the engine so may have the
same heat problem that Tracy is seeing. I did use the Corvette coils
because I could get connectors for them. If I do have coil failures, I
will try a set of the D585 coils. These coils use the smaller connector
like the truck coils.
Speaking of connectors: After months of grief trying to buy them, I now
have the smaller connectors in stock. I still have to sort out the
costs, but I will be able to sell the connectors as well as make up
cables for the truck LS-1 coils.
After Bob Mears comments on lead fouling I have sort of given up hope
on the LS-2 coils being of any help.
