Where can I get a 6.0 with everything for 750??? I want!

Local junkyards want 1500 for engines with 190K miles (with no wiring or computer either)....lower mile units sell for 2500 up
around here and shipping to me is a killer from TX where I see them cheaper...
Does the BBK setup not add value? Or the A/C parts? Just asking questions...not trying to come off rude...
My concern was also on the year and engine size...that's why I was asking for identifying markings/numbers to confirm it's a 6.0...
