My Fairlane Cobra's hood would lift over 2"s when the speed got over 130mph, all the way to 145, and then when I would slow down, the hood would slowly lower back into position. The first time it happened, it scared me really bad, and I slammed on the brakes thinking it would bend the hood double at the hood pins. Those were the days! Young and foolish, but l loved to push that car to the limit, and it would run for miles at 145, and not miss a beat. Joe-JDC
