any advantage to running a gear drive instead of timing chain? i heard the noisy geardrives sound pretty sweet kind of like the whine from a blower. in the summit racing catalog you can buy either "noisy" or "quiet" geardrives. ive only heard one on a car years ago. anyone run one on their boats? do they sound good?
