I have owned a 4.7 dc since mid Feb, and it is a great ride. To me, it does not feel gutless and I do not have 5.7 envy. It consistantly delivers 16-17 mpg and sounds great while doing it. Is it the fastest truck on the road? No, and I did not buy it for that . It is a great truck with a great engine.
Many on this board will tell you to go out and buy the 5.7. Since it is only $1400 more... That is probably true if you could really factory order a new truck...the ones I looked at that had the 5.7 were loaded with a bunch of stuff I was not interested in. Besides, its ok not to spend the extra money ..go buy a 50 inch panasonic plasma and watch 24!!
I have owned 454s, v10, and most small block chevys in trucks and suvs and none of them could beat my 4.7 in a drag race.
Others on this board have stated that your resale will be better with a 5.7. I don't agree with that. I look at this like having a very nice smaller house in a big neighborhood...the value will be there!
If you don't need it, don't pay for it.
I disagree on a few points...
5.7L is faster and I am getting better mileage. It might cost a little more but will tow better and more efficiently. Not only is it JUST the 5.7L but the 6 speed tranny is better as well.
Smoother, more power, less downshifting going uphill. I used to turn off the cruise on my 4.7L because it downshifted and jerked alot. The 5.7L barely downshifts so you can make use of cruise on something other than a flat freeway.
So getting better performance and more power with better mileage is a no brainer to me. Much better choice than all the other add-ons.
You can drag everyone, but you know my 5.7L will beat yours everyday of the week, not that I use it for drag racing (well if I see a Chevy, Dodge, or Ford).
The resale value will be there because if a 5.7L costs more now, it will be there later.
No changing a timing belt... EVER
Besides, I already got a 60" Plasma and the 5.7L is oh so sweet!
