Cam lobe height only reacts with your opening and closing of the valves. The more lift of the lobes the longer the valves stay open drawing in more fuel for more power, but less engine vacuum causing a loping effect. the speed of the camshaft determines the timing of the valves opening and closing fast or slow.
