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. Bob W.
