Moroso Ultra-Pro Aluminum Pro Modified Oil Pans
Moroso Ultra-Pro aluminum Pro Modified oil pans have all of the features and designs that you need for your high-horsepower engine. They have a removable bottom section that provides quick, between-rounds access to inspect main bearings and replace pistons without removing the entire oil pan. The removable section uses a machined channel, which accommodates a reusable square O-ring rubber gasket to provide leak-free sealing. The Moroso Ultra-Pro aluminum Pro Modified oil pans are box-style, all-aluminum pans featuring a maximum-size power kickout, a unidirectional windage tray screen, a block-high crankshaft scraper, and internal baffling. Designed for 2-piece rear main seal Donovan-style big block Chevrolet engines, Moroso Ultra-Pro aluminum Pro Modified oil pans give you the strength, reliability, and access that you need for your engine.
