This is a genuine GM replacement oil pan for the early lt1 and Z28 small blocks. It includes the windage tray, studs and nuts. The GM part number is 00360450 or 360450. This pan has about 2000 miles on it then the thrust bearing on the crankshaft went bad. I have seen new pans like this listed for 900.00. You can see where the part number on the back of the pan was painted over. This will also work on the Camaro 302. I had it on a sbc 350. Thanks
