I have a 2004 mustang 3.8 engine with a broken crankshaft. I also have a 1993 Lincoln 3.8 V6 engine that is junk except for the bottom end. Will the 1993 3.8 Crankshaft work in the 2004 3.8 engine?

The crank should be the same. The stroke on that engine is identical to the 3.8L in the 2004 mustang. What changed was mainly the split-port heads.

Don't blame me if something goes wrong though. It theoretically *should* work but any number of things from manufacturing process to a slight change to accommodate the split-port heads could make it useless... The best I can really say is that it will most likely fit. Whether it will run, or run well, is another story.

My advice: Don't do it unless the Mustang block is going to be junked without this cost-saving measure. If it is then you've got nothing to lose.
