That's a tough question. The 5.9 is a proven engine. So is the 46RE
transmission that goes with it. The 4.7 is an excellent engine and so is
the 45RFE transmission that goes with it. The 4.7 and 45RFE and TCM are
fairly new and there are some kinks that go along with it. Don't worry
about the trouble in here. It was here long before you got here. It's not
really trouble, just some differences of opinion. Some like apples, others
like oranges....then there's the watermelon lovers! ;-D

So what engine would you recommend to someone who was
not going to modify it?
What is the gas mileage difference you have found?
What rear end would you recommend. I would love
something like the 5.9 4x2 I drove but if the 4.7 with
a 3.92 is going to be that fast I would probably
rather have that.
Let me know.
Thanks again--I hope I am not stirring up any mailing
list trouble.
