Do some googling and forum searching. This is a question that's been asked 5 billion times. IMO it's not worth the time/effort. The 4.2 was a great engine, but so is the 2.5. Compare the power/torque numbers before going down a rabbit hole.
I have been reading some via google…..they all say sell you 2.5 and buy the 4.2! I wonder what it would take to swap?
