Best coolant to use in an LT1 car
What is considered the best coolant to use in an LT1 car when doing a flush and refill? Original coolant was Dexcool, but I have heard bad things about it. I don't know if the rumors are true or not, but want to refill with something good if Dexcool is not the answer.
