FAQ
What engine does the Melling 10778 fit?
The 10778 is a replacement oil pump for the Big Block Chevy. Confirm your engine family and pickup configuration before ordering.
Is this a standard, high-volume, or high-pressure pump?
Melling classifies the 10778 as High Volume and Standard Pressure, rated at 70 PSI (pink spring).
Do I need a high-volume oil pump?
High-volume pumps move more oil per revolution than a stock pump, which helps engines with added bearing clearance, remote coolers, or high-rpm use. Pair it with a windage-controlled, properly baffled pan and adequate oil capacity.
Does this pump include a pickup tube?
Melling lists this pump without a pickup in the box unless otherwise noted. Confirm you have the correct pickup for your pan and block, and check pickup-to-pan clearance during assembly.
