Steel Oil Pan for Mopar Big Block — Rear Sump, 5-Qt
Best for custom-coated builds and raw finish enthusiasts. This steel rear-sump pan fits 1967–1987 Mopar B- and RB-engine blocks (361, 383, 400, 413, 440, and stock 426 HEMI). The raw steel surface is ideal for body-work or painting to match a custom engine bay. It offers a 5-quart capacity to balance oil reserve with suspension and exhaust layout considerations. Best for buyers who want maximum flexibility in finish and coating choices. Caution: Raw steel requires finish protection against corrosion in humid environments.
Speedmaster PCE300.1054.01 Mopar BB Pan — Center Sump
Best for buyers seeking a distinctive, track-proven design with a center sump. Speedmaster emphasizes a blend of heritage and modern engineering, aiming at long-lasting performance in road, race, and recreation applications. This center-sump arrangement suits Mopar big blocks where center clearance and pickup routing are favorable. Choose this if you want a pan that aligns with high-performance expectations and a unique product DNA. Limitation: Product description emphasizes innovation rather than explicit fitment clarity for all Mopar blocks.
Steel Oil Pan for Mopar BB — Chrome Finish, Rear Sump
Best for show-quality engine bays. This chrome-plated rear-sump pan supports 1967–1987 Mopar B- and E-body engines, including 426 HEMI variants, delivering a polished aesthetic and corrosion resistance. Best for hobbyists prioritizing visual appeal in addition to reliable oil containment. Caution: Chrome finish adds weight and requires care to avoid pitting or chipping during installation.
Steel Oil Pan for Oldsmobile BEV — Rear Sump, Chrome
Best for comparison when evaluating rear-sump options across brands. While not Mopar-specific, this chrome rear-sump pan demonstrates typical construction and fitment logic: heavy-duty stamped steel with rear-sump geometry. Best for buyers exploring alternatives for mixed-brand builds or gauge-based decision-making. Caution: Not a direct Mopar fit; confirm engine block compatibility before purchase.
Buying Guide
- Finish and corrosion resistance: Raw steel pans offer paint-and-coat flexibility, while chrome or plated finishes reduce corrosion risk and enhance under-hood aesthetics. Choose based on climate and desired maintenance level.
- Rear-sump vs center-sump: Rear-sump pans align with OE Mopar layouts, fitting vehicle bell-housing spacing and pickup location. Center-sump pans can offer different oil pickup routing but may require engine-specific clearance checks.
- Capacity and fitment: A 5-quart capacity is common for street builds, balancing oil reserve with engine clearance. Verify compatibility with your specific engine block (e.g., 361, 383, 400, 413, 440, 426 HEMI) and generation.
- Finish durability: Chrome finishes provide visual appeal but can chip; raw finishes require painting or coating. Consider the driver environment and maintenance plan when selecting.
- Installation notes: Some pans pair with particular pickup and oil pump configurations; ensure gaskets, hardware, and mounting surfaces are clean and correctly aligned to prevent leaks.
