I was afraid of the 6.0 so I kept my 1999 7.3 6 speed until this February 15th, when I bought a 6.4 job #2 with the 20" wheels. Automatic.
My 7.3 had 353,000 miles on it and I am the only one that ever drove it, so I spent enough time in a 7.3 to have some opinion about one.
It is true that the 7.3 is a great engine, but it is totally outdated.
I have 8,000 miles on my 6.4 and here are my comments:
The truck rides like a luxury car. It makes the 7.3 feel like a wood wagon on a logging road.
Quiet. In the 7.3, the noise level is such that you must raise your voice to have a conversation. My wife will not raise her voice. I was always asking "What?" and she would after the 10th time, get exasperated with me usually with the dig that I need to get a hearing aid. Of course, I would get mad because she would not speak up and we usually just gave up.
I have not missed one word since we got the 6.4.
It has the pep of a sports car. I can pass in places on the narrow state roads with short passing areas that I could never do in the 7.3. It passes like a Mustang.
It pulls my 4 horse Sundowner much better.
There is one trip I make almost every week pulling the horse trailer, in fact I am going to make it tonight, that has a 9% grade with 25 MPH curves. The 7.3 had to be in 2nd gear, noisy as a farm tractor. Really grunting to pull that mountain.
6.4 pulls that grade like it is not there and the noise level is about the same as a luxury car in passing gear. You hear it, but it is not objectionable at all.
Another trip I make regularly pulling the trailer has a short but very steep hill with a 65 MPH speed zone. The big trucks usually pull it at about 35 MPH with their 4 way flashers on to keep the fast traffic from rear ending them. I would charge the hill at 70 MPH and about half way up have to downshift topping the hill at 45 to 50 at the best.
The 6.4 maintains the 65 MPH from start to finish. No charging at 70 to make it. Another grade on this same trip is much longer and even the smaller cars have trouble maintaining the speed limit, but the 6.4 pulls that one also without losing any speed. It does turn up some pretty impressive RPM's, but again the noise level is about like a luxury car in passing gear.
Going down those steep grades, the Tow/Haul mode is great.
I have been driving since 1944. I have never owned any of the exotics, but I have owned a lot of ordinary off the floor stock cars. For many years, I flew all over the country and rented hundreds of cars, some of which were the latest and greatest of their type. This truck is the most pleasurable vehicle I have ever driven.
Sneer at the '08 and tell us that you will never ever buy another Ford until they build one that ??????? (fill in the blank with your favorite gripe), but you just don't know what you are missing.
When I thought I was going to order a truck, I told the dealer "No rear view camera, no step in the tailgate". Anyone that needs that stuff should be in a rocking chair, not a truck. Now that I have them, I would never be without them.
Stick with that noisy rough riding 7.3 just so you can say you have a "real" diesel. You are going to miss out on a lot of fun driving.
By the way, I still own the 7.3. I have driven it one time since I bought the 6.4. If the 7.3 were a better truck, I would take it on my trip tonight. NO WAY.
The 7.3 is for sale.
