Ford 8.8 swap?

I take it you already have this 8.8? I guess if you already have it and the length will work out / axles brakes can be reused it makes financial sense. I would look for a Dana 60 rather than stuffing an 8.8 under a Mopar. As for 3.73's with a turbo shouldn't be much of an issue depending on tire size. You might be overall happier with something like a 3.23 gear for cruising - all depends on what you are wanting it to do??
