The Speedmaster PCE300.1058.01 is a two-piece rear main seal, driver-side dipstick, rear-sump oil pan designed specifically for Chevy Small Block 350 engines from 1955 to 1979. The 7-quart capacity provides increased oil volume over stock, helping maintain consistent oil pressure and lubrication during high-performance and drag racing applications where fluid surge is a concern.
Finished in a zinc coating for corrosion resistance, this rear-sump design is ideal for drag racing setups where front-to-rear weight transfer can cause oil starvation in conventional pans. Fitment covers 1955–1979 Chevy SBC 350 applications with a two-piece rear main seal and driver-side dipstick location — verify your engine's RMS style and dipstick position before ordering.
