I have a 7.3 Powerstroke engine for sale. It was bought from a parts warehouse when the inventory sold. It is completely fresh, has pan, front cover, rear main seal and housing. No fuel system, intake, or valve covers. Has new oil cooler with it and gaskets. I do not know who built this. "THERE IS NO WARRANTY EXPRESSED OR IMPLIED" Selling cheap enough you can pull heads and pan to inspect if you want. If you have questions please ask.
