Designed to fit seamlessly with the stock engine, the Milodon 31665 oil pan requires no modifications for installation, making it a straightforward upgrade for Pontiac GTO and Lemans owners. The pan comes with a baffled design, which minimizes the amount of oil slosh during aggressive cornering, helping to maintain optimal oil pressure and ensuring stable engine performance.

Equipped with a deep sump design, the Milodon oil pan is perfect for high-performance applications, ensuring ample oil supply to the engine during hard acceleration and cornering. This is a crucial factor for those seeking to extract maximum performance from their Pontiac muscle cars. Furthermore, the deep sump design helps to prevent oil starvation issues when running high-performance aftermarket components, such as larger carburetors, high-lift camshafts, or nitrous oxide systems.

In summary, the Milodon 31665 Road Race Oil Pan is a top-quality upgrade for Pontiac GTO and Lemans models (1964-1973) with a 389-455 engine. This oil pan offers numerous benefits, including improved durability, increased capacity, reduced unsprung mass, and enhanced oil flow, making it a must-have for any serious muscle car enthusiast seeking to elevate their vehicle's performance and reliability.
