400, 425, 455, 1965-1976, A, B and C body Oldsmobile


Out of stock



This oil pan will fit Oldsmobile big block cars 400, 425, 455, 1965-1976, A, B and C body cars.

This oil pan was duplicated from an NOS W30 GM oil pan.  It was made with the correct GM specs and has the correct drain plug hole with a nylon gasket.  It is made from heavy weight steel just as the original was.  It is the 5 quart with oil filter design.

Big block and small block oil pans are different.  We have seen other companies sell small block oil pans as big block oil pans.  The small block oil pans will bolt on but they are not correct.  The big block oil pan greatly improves the oil circulation with the GM contour added at the lower sump.  This contour is duplicated on this oil pan.

The small block oil pans are contoured evenly back to the lower sump and do not have the raised bump before the lower sump like the big block.

This oil pan also has the raised contour around the drain plug, just as the original did.

Notice the correct inner baffle and the correct drain hole location.  Other reproductions do not have the drain hole in the correct location.  Don’t lose points at the nationals for the having the wrong oil pan!

The oil pans are coated with EDP, Electro-Deposit Primer.  This coating seals and protects the oil pan from rust and corrosion.  This coating does need to be stripped but can be scuffed for better paint adhesion.

Original oil pans tend to have a crushed lower sump and are rust pitted.  Save hours in your restoration with new this GM quality replacement!
