Chevy Oil Pump Block-Off

The Chevy Oil Pump Block-Off from MOROSO is a precision-engineered aluminum plate designed for high-performance Chevy V6 and V8 engine builds where belt-driven accessories are eliminated or relocated. Whether you're building a dedicated track engine, converting to external serpentine systems, or optimizing underhood real estate for custom fabrication, this block-off plate seals the factory oil pump mounting location with a clean, professional finish. It's an essential solution for engine builders and performance enthusiasts who need to eliminate unused factory components without compromising structural integrity or oil system reliability.

Machined from aircraft-grade aluminum and finished in black anodized coating, the Chevy Oil Pump Block-Off provides corrosion resistance and a refined appearance that matches modern engine bay aesthetics. The anodized surface protects against oxidation in high-heat environments while the precision fit ensures proper sealing without modification to factory bolt patterns. This block-off plate maintains the structural load path of the engine block while cleanly concealing the factory oil pump cavity, eliminating the need for temporary plates or improvised solutions that can leak or loosen under vibration and thermal cycling.

Installation is straightforward for anyone with basic mechanical knowledge and standard hand tools—simply remove the factory oil pump assembly, clean the mounting surface, and bolt the block-off plate in place using existing factory fastener locations. Serious engine builders, street rod fabricators, and competition mechanics rely on MOROSO block-off plates to achieve clean engine bay presentations and ensure system integrity on LS conversions, custom fuel system installations, and stripped-down track builds. This compact, lightweight solution (0.15 lbs) fits within standard underhood dimensions (3.75 x 1 x 5 in) and is compatible with both small-block and big-block Chevy applications across multiple generations.
