Ensure Your Small Block Chevy Has Adequate Oil Pressure and Volume with Our Direct Replacement SBC High Volume Oil Pump

There are many scenarios where a stock-volume oil pump won't provide the protection your engine needs. Engines with loose clearances (budget rebuilds or high-mileage engines) will need more oil volume to maintain a desired pressure. Engines operating at sustained high RPM (racing applications) also typically need more oil volume to maintain pressure in all oil galleries. This SBC high volume pump works with the stock SBC oil pump shaft bushing, but we recommend an aftermarket .

This high volume oil pump moves 25 percent more oil by utilizing 1.500-inch long internal gears, which is .300-inch longer than stock pumps. Another benefit of a high volume oil pump is increased pressure at idle, providing some much needed peace of mind on the street. This SBC oil pump is preset to 55-65 psi to satisfy most mild-mannered SBC engines. If additional oil pressure is needed, you can always change to one of the included higher pressure springs for a quick boost in oil pressure in your SBC oil pump if needed. Combine this small block Chevy oil pump with a new 5/8-inch to fit your stock-style oil pan.

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

• Comes with three (3) pressure relief springs:
  • 55 psi (preinstalled in pump)
  • 65-70 psi (orange spring in the box)
  • 80-90 psi (yellow spring in the box)
• This pump is the same depth as a typical SBC high volume pump and the cover has been modified to avoid cavitation of the oil.
• Installation of your oil pump pickup tube will require the proper tool or equivalent shop made tool using notched steel tubing or 5/8 open end wrench after checking and setting installation height with your oil pan.
• Recommend brazing or TIG welding pickup to oil pump body for installation security.
• Replacement and kit sold separately if needed.
