What anti-freeze do you guys use in your LS1s? I yanked the radiator the other day and I'm going to put it back soon. What do y'all recommend using?

Dexcool is the recommended coolant and the one gm uses in all their cars. If your flushing the whole system out you could use any coolant as far as i know, but I usually stick with dexcool. Couple more bucks but I do it for the peace of mind.

by the time you're done paying for the hydrometer and the distilled water, you are at about the same price

Not using distilled water introduces minerals into the coolant. Some places have water that can cause problems, some don't, but any is worse than none. Minerals can precipitate out and cover interior surfaces, which reduces the transfer of heat. They don't do anybody any good.
Dexcool has problems in systems that are not airtight. Even coolant that goes out into the collection bottle and back in when cooling sees interaction with air. This is bad in Dexcool-land. The idea that it's good for 5yrs/100k miles leads people to think they will always get that much protection under all circumstances. Maybe. Maybe not. Failure of Dexcool produces brown gummy goo, and nobody needs that in their cooling system.
Changing over to green coolant is easy. Two-three year changes is no hardship. Peace of mind is good to have. I've never seen green coolant produce gooey and gummy deposits.
Cost? Most of you guys can't seem to spend enough on your cars so what's the problem with perhaps a couple of more bucks on coolant?
