I don't have LS1 coils so I can't contribute much here. But I was wondering if anyone with a desire to test this duty cycle theory could simply hook up two coils instead of 4 to a 13B (1 for leading plugs and 1 for trailing) or if you really want to stress it one coil for all four plugs. If the failure is due to duty cycle that would show it pretty quickly. Not sure if doing that is feasible though – don't know what the charge time requirement is for these coils.

FWIW, I have the LS1 coils with over 200 hrs on them now. They are one of the few things that have not given my any problem. My under cowl temps are relatively low because the air does not pass through the radiator until it is on the way out of the cowl. That's one indication that heat is probably Tracy's culprit.
