The Speedmaster PCE300.1090.02 is a black finned aluminum oil pan designed specifically for early Gen 4 Big Block Chevy 454 engines with a two-piece rear main seal configuration, covering applications from 1965 through 1990. The finned aluminum construction helps dissipate heat from your engine oil while reducing overall weight compared to a stock cast-iron pan, making it a smart upgrade for performance street and racing builds.
The aggressive black finish and classic fin styling give your engine bay a clean, purposeful look that complements any BBC build. Designed as a direct-fit replacement for compatible 2-piece early Gen 4 454 applications, this Speedmaster oil pan delivers a reliable, leak-resistant seal and the kind of quality fitment you expect from a dedicated performance upgrade.
