Torque Curves for all motors but 4.6L 2V
Ford released the torque curves for all the motors in 2009 - 2011 in their marketing booklet. I took pictures and have the results:
Here's the breakdown:
3.7L
1500 rpm = 237#
2000 rpm = 250#
2500 rpm = 244#
3000 rpm = 250#
3500 rpm = 256#
4000 rpm = 275#
4500 rpm = 269#
5000 rpm = 262#
5500 rpm = 265#
6000 rpm = 262#
4.6L 3V
1500 rpm = 269#
2000 rpm = 275#
2500 rpm = 287#
3000 rpm = 287#
3500 rpm = 302#
4000 rpm = 320#
4500 rpm = 315#
5000 rpm = 300#
5500 rpm = 280#
6000 rpm = 255# (Redline)
5.0L
1500 rpm = 275#
2000 rpm = 302#
2500 rpm = 315#
3000 rpm = 327#
3500 rpm = 350#
4000 rpm = 362#
4500 rpm = 379#
5000 rpm = 356#
5500 rpm = 348#
6000 rpm = 315# (Redline)
5.4L
1500 rpm = 260# ?
2000 rpm = 315#
2500 rpm = 340#
3000 rpm = 356#
3500 rpm = 365#
4000 rpm = 365#
4500 rpm = 363#
5000 rpm = 350#
5500 rpm = 297# (Redline)
6000 rpm =
Ecoboost 3.5L
1500 rpm = 375#
2000 rpm = 381#
2500 rpm = 415#
3000 rpm = 420#
3500 rpm = 413#
4000 rpm = 413#
4500 rpm = 400#
5000 rpm = 390#
5500 rpm = 350#
6000 rpm = 275# (Redline)
6.2L
1500 rpm = 360#
2000 rpm = 372#
2500 rpm = 390#
3000 rpm = 387#
3500 rpm = 397#
4000 rpm = 406#
4500 rpm = 434#
5000 rpm = 413#
5500 rpm = 397#
6000 rpm = 372# (Redline)
3.7L has an impessive torque curve and the Ecoboost has the best low rpm torque curve.
4.6L 3V has a decent torque curve while the 5.4L 3V has a good torque curve.
5.0L and 6.2L have the worst torque curves in the low rpms.
The 3.7L, while having a good torque curve, had lower outputs.
The Ecoboost Looks to be the best motor to tow with a side of any current overheating/transmission problems.
While the 6.2L has a terrible torque curve, it's output is high enough to get past that.
All motors have the curve start at 1000 rpm while the 5.4L starts at 1500 rpm. Curve below 2000 rpms on the 5.4L looks inaccurate as the curve just starts off at 1500 rpms. Don't know why they started testing so late in the rpms on the 5.4L 3V.
Here's the breakdown:
3.7L
1500 rpm = 237#

I definitely would not classify the 6.2 as a terrible curve. It comes on at around 1800 and maintains a flat consistent torque all the way to red line. It doesn't come on as early as the ecoboost but it is a very respectable curve and is a great truck motor. It was designed as such and it performs as such.
Terrible isn't an acceptable description. It's more of a jab at the 6.2 than anything.
If I was to add direct injection and twin garrets to a 6.2 I'm sure I could get the torque to come in at 1400 rpm without a problem. Is also would be making 800 HP and 740 flbs of torque with better mpg than it currently gets. If Ford was to add the turbos to it , I'm sure that would open the door to throw some jabs at the 6.7 .
But thanks for the data. I'm just not big on your commentary.

Interesting
I recently just purchased the 5.0 and have been pretty impressed. Looking at the torque curves though, at highway speed ~2000 rpm, the 5.0 is more like the Chevy 5.3. The 5.4 looks like a much better towing motor as it's putting down more torque again at highway speed.
My last truck was a Nissan Titan. I went Titan for the torque. The price was fuel economy though. Thus far it seems the 5.0 is similar to the Titan when towing my boat. The charts tell a very different story though. Are these really Ford charts? 5.4 has more torque at tow speed than the 5.0?

The pics are from the new F150 and Super Duty display at the Ford dealership. The charts were in the plastic page book marketing how much better the F150 was over the competition.

However with the combination of high horsepower, the 6.2L is a powerhouse, it just could have better torque output in comparison to it's peak rated torque.
Obviously this is not uncommon as all truck makers are doing this for the bragging rights of having the most horsepower and torque. This is common for a 4 valve, dual overhead cam setup. The truck isn't tuned for the flattest curve but the highest output curve.

The 5.0L is 50 lbs less and has 50 more horsepower. That is why this truck is so much faster than the 5.4L. Horsepower rules when racing from a stop, which is what all reviewers do.
