If the entire window sticker is on the truck, the axle ratio is on the right
side in small letters. It's a toss up which engine is faster. I couldn't
beat the 4.7 when I was stock but he couldn't beat me either. That's auto
on both. Of course you can't get anything but auto on the 5.9. There's a
lot more after-market parts for the 5.9 because it's been around longer but
the 4.7 is slowly catching up. The lower the rear-end gears the faster the
low-end acceleration but you'll sacrifice top-end for lower gears. Depends
on how fast you want to go. Initially, you won't be able to go faster than
the speed limiter will let you go (~112-115 mph) and you won't be able to
rev your engine beyond the rev limiter speed. Buying an HP PCM or having
your stock one modified will change all that. 3.55 gears if you want mpg.
3.92 gears if you want better acceleration or you're going to tow. 4.10
gears if you're towing real heavy or considering the track.

Subject: DML: Acceleration and Axle Ratios
Hi Everyone,
I am new to the mailing list and have a few questions.
I am looking to buy a 2001 Quad Cab 4x4. I went to
test drive a few and all I could find were the 4.7V8
with an auto.
I was decently empressed with the acceleration but
wanted to find out what a 5.9 could do.
I found a 5.9 Quad Cab 4x2 on their lot and drove it.
It was very very fast.
My questions are as follows:
--How can you find out what the axle ratio is by
looking at the window sticker(no window sticker had it
posted, 3.92, 3.55, 3.21?
--What is the weight difference between a 4x4 and 4x2
quad cab?
--Why do you think the 5.9 auto 4x2 was that much
faster than a 4.7 auto 4x4?
--Do the gear ratios make a lot of difference as far
as acceleration goes?
--I have heard the 4.7 is supposed to out perform the
5.9--the numbers don't show that(hp, torque) and so
far neither does the driving. Was it the weight issue
or a gearing issue an engine issue that allowed that
4x2 to be so fast?
--What do you think the fastest combo for the 4x4 quad
cab is (rear end and engine---I am definately getting
and automatic)?
Thanks for all the help.
Bob H.
