FWIW, I run 25° timing at idle

I've got 28* at idle programmed into my LT1. That timing gives about the lowest injector pulse width. It could idle forever on the hottest day without overheating only using a 16" electric fan strapped to the radiator. And that fan doesn't even have to cycle on that much.
