SBM Oil Pan - 273-340

The SBM Oil Pan - 273-340 from MOROSO is purpose-built for small-block Mopar applications, delivering reliable oil containment and superior cooling for street and performance builds. This oil pan is engineered to replace undersized factory units, providing increased oil volume and improved circulation—critical upgrades for engines running sustained RPM or modified cooling systems. Whether you're upgrading a 273, 318, or 340 cubic-inch Mopar engine, this pan handles the demands of both daily driving and spirited weekend cruising.

MOROSO's SBM design maximizes internal baffling to reduce oil slosh and maintain consistent supply to the pickup during cornering and acceleration—a key factor in preventing starvation on modified engines with aggressive cam profiles or high-load conditions. The pan's cast construction ensures durability under thermal cycling, while its optimized sump depth allows clearance for steering linkage and suspension geometry on tight engine bays. At 13.4 lbs and measuring 12.5 x 11.25 x 26.75 inches, the pan integrates seamlessly into OEM engine compartment layouts without requiring custom fabrication or exhaust relocation.

This upgrade is essential for anyone rebuilding or modifying a small-block Mopar with aftermarket components—tuners, engine builders, and enthusiasts working on Dodge, Plymouth, and Chrysler muscle cars will appreciate the additional capacity and flow characteristics. Installation requires basic hand tools and mechanical familiarity; verify year and displacement compatibility before ordering. The SBM Oil Pan - 273-340 pairs well with high-performance filtration systems and synthetic oils for extended drain intervals and enhanced engine protection.
