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.
