This oil pan is designed for custom applications requiring a front sump to clear chassis and suspension. Pan has a deeper sump allowing for the installation of a windage trap and baffling for improved oil control. Oil pan clears up to a 4.125" stroke crankshaft. The thick outer flange has -10 AN fittings for use with a remote mount oil cooler/filter. This oil pan is used in engine swaps so you will need to check measurements before purchasing to ensure proper fitment.
