The Speedmaster PCE473.1001 Valley Pan is purpose-built for Mopar Chrysler Big Block RB engines displacing 413, 426, and 440 cubic inches. The zinc-plated finish provides a layer of corrosion resistance, helping to protect the pan in demanding under-hood environments while giving the engine bay a clean, finished appearance.
Designed as a direct-fit replacement for the factory valley pan, this piece helps seal the lifter valley and maintain proper engine cleanliness on your RB block build. Whether you are refreshing a classic Mopar or assembling a performance engine, the PCE473.1001 offers a reliable, correctly fitting solution for 413, 426, and 440 RB applications.
