Melling’s new oil pump for small-block Chevys, dubbed the Shark, features asymmetrical, helical-cut gears for smoother output than a traditional spur-gear oil pump, along with reduced power requirements and higher volume output. The new gear design provides the engine with an improved flow of oil without the usual pulsing found in traditional gear pumps. The reduction in the pressure ripple from the pump can also provide benefits to the distributor and camshaft drive.
