So I found a 440BB

I wouldn't say they are a complete loss but not worth what he is asking considering they may not be salvagable. I got a 69 hp 440 engine with my GTX that was sitting outside since who knows when. The oil pan was rusted through, a valve cover was missing, no covering. After pulling it apart the #6 piston was stuck solid, soaked in atf for 2 weeks, heated, still stuck. Finally drilled and beat it out. The bores cleaned up to .040" over and it is a good runner now. It was not something I would have paid for outright.
