I've heard good things about the new 5.0

The new 5.0 is awesome. I've only test driven it though. But I am concerned about that fact that the torque peak is at over 4,000 rpm. It's too bad that Ford finally caved in to the automotive mags that continually ragged them about their horsepower. Ford bravely pointed out that it was torque production that counted. The 5.4 did pretty well in that regard; at least peak torque was in the 3,400 rpm range. Now we get the high rev'ing V-8 that the competition has had. Not sure that is a step forward; at least while towing. GREAT sounding motor though and it moves well empty.

Not knocking anyone's 5.0! It's a very nice engine.

Doesn't the 5.0 out-torque the 5.4 through most of the rev range though? My 5.4 was a great torquer, and if the 5.0 out-torques it down low plus likes to rev and can breathe at higher RPMs, then it should be great for towing and all-around! The 5.0 truly sounds like a great engine (and from what I have heard, sounds great).

Most non-towing people don't understand that torque generation is a more important stat than horsepower. Not a problem on sites like this.

But I think there may be some here that see a torque peak at a higher rpm, and automatically think it won't be as good for towing.

As someone already implied, I think the 5.0L generates more torque at it's torque peak. The question is, how much torque is the 5.0L generating at the 5.4L's torque-peak rpm (3400 according to Acadianbob)?

If the 5.0L generates about the same amount of torque @ 3400 as the 5.4L, then continues to generate more torque thru 4000 rpm....that's a good thing!

The Ecoboost engine appears to generate less torque at the 5.4L's peak, but it quickly makes up for it within about 500rpm (IIRC).

I think the 5.0L is really meant to be the improved replacement workhorse for the 5.4L, with the V6-turbo intended more fpr part-timer towing (a step-up replacement for the 4.6L 3-valve).

Right. The 5.0L V8 is not an Ecoboost engine.
THAT would be a screamer!!

Ecoboost has more power and torque than the 5.0 so I believe there is a complete shift. The 5.0 is probably not meant to replace the 5.4...It is meant to provide a viable option for those truck buyers klinging to V8's and skeptical about a blown v6.

Yep right on!

And that IS a good point on 5.0 torque. It would be interesting to see the torque output of the 5.4 and the 5.0 both at about 3,500 RPM. It's quite possible the 5.0 matches or exceeds the 5.4 at that speed. Still, too bad that the peak is so high on the 5.0. I still say Ford caved in on this one.

I just bought a 2011 F150 4X4 Lariat with Max Tow, 7650 GVWR, short bed. We are considering the Rockwood Ultra Lite 8280WS. Anyone out there have an experience with that?
