High Volume Adjustable Small Block Chevy SBC Oil Pump, 5/8 Pickup

There are many scenarios where a standard-volume oil pump won't provide the protection your SBC engine needs. Engines with loose clearances (quick rebuilds or high-mileage engines) will need more oil volume to maintain a desired pressure. Engines operating at sustained high RPM (racing) also typically need more oil volume to maintain pressure in all oil galleries. 

These high-volume oil pumps move 25% more oil by utilizing 1.500" long internal gears, which is .300" longer than stock pumps. Another benefit of high volume oil pumps is increased pressure at idle, providing some much needed peace of mind on the street. 

All components are hand-selected for perfect fit and function. The high-nickel body and end plate have been machined to balance the pressure at all RPMs, which reduces cavitation and increases longevity. This adjustable oil pump includes three pressure springs. The general rule of thumb is 10 PSI for every 1,000 RPM, so these springs will allow you to tune the system to your needs.
