The long blocks are interchangeable for any Vulcan 3.0. They also put DOHC duratec 3.0's and SHO 3.0's into the Taurus, which will not work, so make sure you're looking at the right engine. If you get a vulcan from a FWD car (taurus, topaz, sable, tempo, probe, etc), make sure you replace the head gaskets and lower intake manifolds with the ones from your ranger. Basically, you want to keep as much of your Ranger stuff as you can, and just switch out the longblocks.
