If a vehicle swap turns out to be the better option - and I really think it is - then a whole world of thrifty, long-legged choices lie at your feet. 84 miles is a lot of distance to cover on a homebrew swap. I'm not trying to cast aspersions on your wrenching ability. But you don't see people swapping little diesels into old LeSabres, so you'd be wandering off into the engine swap hinterlands pretty much by yourself. The difficulties you face are going to be new to everybody, which means you get to be Patient Zero in trying to work out the bugs.

If you were trying to pull this off with a small truck you'd have plenty of experience out there to draw on if you needed it, not to mention more room under the hood and a broader range of engines to choose from. But this? Yikes.

If it were me, I'd sell the LeSabre in favor of a good used hybrid.
