Nope, cant. The engine mounts laterally in the stratus, whereas the intrepid it mounts longitudinally -- thats the first hurdle, second hurdle is the engine mounts would have to be custom made for a 3.5, then finally the 3.5 is too big to fit in the engine compartment.
However, with some parts swapping, you can mount a 2.7 out of a stratus into an intrepid or vice versa. Just not 3.2/3.5.
Ive been looking for a Stratus to experiment with.. either doing a 2.7 to 2.4 DOHC swap or 2.7, 3.0 swap. Electronics look like they would work.
