Well the dohc motor in the sable is the same that is in the taurus, it is the duratec 3.0. From what I hear they are rated at 200 horse. THey scoot pretty good. I have never gotten a streight answer on weither or not they will bolt up to the transmission in the ranger. I do know that the front wheel drive vulcan and duratec share the same transmission. So this is a big if, and I mean BIG, if you could find a 3.0 from like a lincoln ls, they are rear wheel, and came with the 3.0 duratec. I imagen that it would work with the vulcan tranny.
But Here is the hang up I found looking at doing this swap. There is so much electircal and fabrication work that would be required to make the swap work, it is almost not worth it, when you can swap in the sohc 4.0 and have 207 hp. But the 3.0 gets better gas milage, which could save you in the long run.
there are several threads on here about the duratec 3.0 swap. I have not heard of any who have done it.
If you like the idea of doing the swap, don't let anyone on here tell you not to do it, because it would be easier to do a v8 blah blah blah. Dare to be different man. Sorry I can't be of more help.
