a lot of things can "happen" to the car, the motor can blow for all you know. The first signs of detonation (if you don't have a knock sensor) are the marbles in your motor sounds.

what have you done to the car that you think there is a risk of detonation?

make sure you are running proper timing and fuel and you will avoid it

also like I said detonation is like marbles under the valve cover. Get on a hill at 2500 rpm in a high gear and floor it ... listen for those sounds as the engine loads.

no that happens when you have no gas and go extremely lean.

ping is audible, thats about it. then trails of white smoke.
