Overview

The Moroso 20145 is a dedicated rear sump oil pan tailored for GM LS Series engine conversions. With a 5-quart wet sump capacity, this pan is 6 inches deep, 8.5 inches wide, and 8.375 inches long, offering crucial clearance for crankshafts up to a 4.25-inch stroke when paired with most steel rods. Its fabricated steel construction, finished with a black powder coat, provides exceptional durability and corrosion resistance, essential for both street and track environments.

Key to its performance is the internal oil control system, featuring a trap door and a rear anti-climb baffle that effectively manage oil movement under aggressive acceleration and cornering, preventing oil starvation. The integrated billet aluminum spin-on oil filter adapter (22mm thread) allows for the use of a Moroso 22463 or stock OEM oil filter directly on the pan, eliminating the need for complex remote filter setups. This adapter also includes a 1/4" N.P.T. port for convenient sensor installation.

Further enhancing its utility, the Moroso 20145 oil pan is designed to work with standard LS car application dipsticks, simplifying the setup process. It also comes equipped with a magnetic drain plug to help capture metallic particles, contributing to engine longevity. For optimal performance, Moroso recommends using their 24050 oil pump pickup, designed to fit seamlessly with this pan and a range of GM LS oil pumps.

This oil pan is a direct fit for LS engine conversions requiring a rear sump configuration, offering a high-quality, application-specific solution that addresses both performance and packaging challenges inherent in engine swaps.
