Where's OUR Horsepower?

This subject is very frustrating to me because Ford HAS the goods in their parts bin to offer us the power crown.

or hell, another contender for the performance crown would be a v10 based on the 4.6 stroke. it's been done in a mustang before with pretty damn good results... dohc v10, 5.8L, made upwards of 400hp/420tq if i remember right... that would take no effort to do.
or hell, drop the v10 in the f150. exactly as it sits right now... would pretty much shut toyota up real quick

I really think (but don't know for sure) that the engine in the 5.4L is limited by the tranny that is used and not the technology for producing more/better power out of it.
If they had a stronger tranny with the correct "truck" ratios then I would imagine they'd have a stronger engine.
I really think the V10 would grenade the 4 speed or the Expy's 6-speed. But I'm no automagic tranny wiz.

It needs more torque but I'd take a 348/368 4V V8, I guess. BTW, the specs said it makes 260kW which converts to 348HP...not 389. Where did that number come from or did I convert it worng?

290kW = approx 389hp (forthcoming version will be 325kW)
And the current is a rather "energetic" 389 ponies - if you catch my drift
As for using it in a "real" truck.... I would advise against it (unless the forthcoming 420hp version proves better).
The engine doesn't really make a whole lot of torque until 3500rpms - and then, thanks to its long stroke, the party is all over by 6grand.
Great for a car (or a light "sport truck" like mine) not so good for a heavy Crew Cab F150.
The better motor would be the turbocharged 4.0l I6.
Been dynoed at over 1000hp:

(language warning on some of the comments)
Thing makes 325lb-ft from 1500 rpms - all the way to redline (6500)
Max torque is about 410lb ft@2000-4500rpms (converting in head)
This is for the current 360hp version. The 420hp version should have MUCH more torque

IMO...sounds like "User error". Come visit the V10 forum sometime. Most reports are in the 14-15mpg highway...and city 12-13mpg. In an all OEM setup.

The hp/torque numbers for bragging rights should go away like the dinosaurs. In today's world...and increased oil costs and instability, FORD should be thinking of economy over hp/torque ratings. The current 5.4L 3v is a GREAT engine and suites the F150 perfectly. Does everything it was designed to do.
The 6.2L V8 "Hurricane" (or whatever they are calling it this week) will be the next generation V8 for FORD. It will have the high hp/torque figures, but with better fuel efficiency. The 6sp Auto tranny will certainly help with putting the power to the ground, but keep those mpg's up.
Anyway...just my .02
