7qt Oil Pan Kit RR Sump SBF 351W 79-93 Zinc

The 7qt Oil Pan Kit RR Sump SBF 351W 79-93 Zinc from Weiand is a purpose-built deep-sump solution designed for high-performance Small Block Ford applications, particularly the iconic 351W engine in 1979–1993 Ford Mustangs and comparable platforms. This rear-sump configuration addresses a critical need for builders and enthusiasts running aggressive suspension geometry, forced induction, or extended track duty where stock pan capacity and clearance become limiting factors. By upgrading to a 7-quart capacity with 9-inch depth, you gain oil volume that improves cooling characteristics and reduces aeration under sustained lateral or longitudinal load.

Weiand's fabricated steel construction with gold zinc finish provides corrosion resistance and durability essential in harsh underbody environments. The kit arrives complete with gasket, fastener hardware, and pickup tube assembly, eliminating the need to source components separately. The 9-inch depth maximizes clearance compatibility with custom frame-mounted components, transmission tunnels, and low-profile sump design while the rear-sump placement suits vehicles with modified suspension or those requiring weight distribution adjustments. Steel construction ensures rigidity under pressure and thermal cycling common to modified engines, while the zinc plating protects against rust and extends service life in moisture-prone conditions.

Enthusiasts and professional builders working on 351W engines—whether for drag racing, street performance, or off-road duty—benefit most from this kit's increased capacity and purpose-engineered sump design. Compatibility is confirmed for 1979–1993 Ford Mustangs and other SBF platforms utilizing the 351W block. Installation requires mounting to the engine block per Weiand specifications; the included pickup and gasket ensure proper oil delivery to the pump inlet under all operating angles. Verify clearance with your specific frame, suspension, and drivetrain configuration before installation to ensure the 14 × 12 × 27-inch envelope fits your application.
