Melling Engine Oil Pump P/N:M-84BHV-S
Keep engine oil circulating under steady pressure with the MELLING oil pump M-99HV-S, a high-volume, gear-type replacement that draws oil from the sump and feeds it under pressure through the engine's oiling system. It's a direct-fit replacement for hundreds of Chevrolet applications, including the 1994-1996 Chevrolet Impala [V8-5.7L], 1988-1995 Chevrolet C1500 [V8-5.7L], 1969-1974 Chevrolet Blazer [V8-5.7L], and 1962-1969 Chevrolet Impala [V8-5.3L] — see the Buyer's Guide tab for the full list of 464 applications.
Melling machines its high-volume gears to close tolerances to help support proper oil pressure and efficient pump operation. The design is intended to raise oil pressure at idle and add flow for demanding use. Each pump is individually tested for pressure and flow in conditions that mimic real engine operation. The pickup tube and inlet measure 0.750 in (19 mm), and the housing carries two 0.25 in mounting holes. Made in the United States.

This part cross-references / interchanges with the following part numbers:
What is the MELLING oil pump M-99HV-S?
It's a high-volume, gear-type engine oil pump that draws oil from the sump and delivers it under pressure through the engine's oiling system, supplying roughly 25% more volume than a stock pump.
What's included with this MELLING high volume oil pump?
It ships with the pump cover, gears, intermediate shaft, drive shaft, and pickup screen. Mounting bolts and gaskets or seals are not included.
Does it fit a 5.3L Chevrolet?
This pump is listed for many Chevrolet V8s, including the 1962-1969 Chevrolet Impala [V8-5.3L]. Check the Buyer's Guide tab to confirm your exact year, model, and engine.
Is this a high-pressure oil pump?
No. It's a standard-pressure, high-volume pump with a non-adjustable bypass, so it increases oil volume rather than raising the relief pressure setting.
What is it made of and where?
The housing and cover are cast iron with steel spur gears and a steel drive shaft, finished with a rust-preventative coating. It is made in the United States.
