Now THAT is pretty cool. I was wondering how it held up under that type of driving. I wonder if the Edelbrock A-B stuff is the same, Advance Auto has it for about the same price as the Moroso stuff. It is just a really small spot, I will try to get a pic tomorrow. I didn't actually make a hole, it just got thin enough to push the metal out and put a crack down the middle of the bubble. Hmmm....
