A stamped steel, front-sump oil pan was originally used on 428 CJ and SCJ engines. Ford identified these oil pans using basic part number 6675. Oil pans installed during engine assembly were painted blue along with the block, heads, and other engine items.
Two different oil pans were used. 1968 Mustangs equipped with a 428 CJ engine received an oil pan identified by service part number C6OZ-6675-A. This same pan was also used on other FE engines. Other common applications include 1967-1969 Mustangs equipped with a 390 and 1968 427 engines. This pan differs from some other FE pans by including indentations along the rear sides to provide steering linkage clearance. Note the internal baffle.

A slightly different pan was used during the 1969 and 1970 model years. This pan, identified by service part number C9ZZ-6675-D, is unique to the 428 CJ/SCJ and includes a slightly different internal baffle. I've heard that it was introduced around October, 1968. That means that cars built early in the 1969 model year may well have come with the C6OZ-6675-A pan.

A windage tray first appeared at some point during the 1969 model year. This stamped steel tray, sandwiched between the block and the oil pan, is sealed in place using two oil pan gaskets. The tray was used to keep pooling oil away from the crankshaft as it rotates. This part was serviced using part number C9ZZ-6687-A.

The 1975 Master Parts catalog also lists a pan for "All High Performance Vehicles" under service part number C8AX-6675-A. This is a Ford Muscle Parts item that was never used in production. It is described in the MPC as "Deep sump - 7 qt. - requires special pick up".
