Throughout Ford, the V8 lineup is undergoing a significant makeover. With the debut of the 2009 F-150, Ford released a new version of the 5.4l Modular (also called MOD or Triton) V8. This new engine, while sharing many components with earlier models, will sport meaningful improvements in horsepower, torque, and fuel mileage. This update will position the engine’s torque in the neighborhood of much larger V8 engines, such as Toyota’s 5.7l iForce, or GM’s 6.0l Vortec Max. The new 5.4l will see only truck duty, however.
Later this year, Ford will also finally release the BOSS V8 engine, and once again this engine will be truck-only. The engine will be a 6.2l SOHC V8 with an expected 425hp and 450 ft.lbs of torque. The first vehicle with this new engine is to be the 2009 Navigator, the one vehicle in Ford’s lineup that desperately and unquestionably needs the engine. Around the end of 2008, this engine will finally make it to the F-150, and maybe even the Expedition.
im guessing 350/400.... hell with my edge and intake i should be around 390ft/lb at the crank... thats only 25ft/lb which is what most tuners offer...so i would hope that they would make at least that

320 hp, 380 lb.-ft is my guess. Notice the article said the upgrades will position the engine's torque in the neighborhood of it's larger compeitors, not it's horsepower.
I'm guessing around 330 hp 380ft*lb. I'd be quite happy with that also. It would be cool if they could be competetive with the smallest displacement. I hope for fuel economy improvements too!!
The consensus seems to be about 380 ft-lbs torque. So using that number and the current specs of 365 lb-ft at 3750 RPM and 300 HP at 5000 RPM at that speed the engine
is making 316 lb-ft of torque. Using these ratios then:
380 ft-lb at 3750 RPM = 270 HP
316/365 x 380 = 329 lb-ft at 5000 RPM = 313 HP.
Now if you can hold that torque to 6000 RPM then you have 375 HP. I'm not sure that power at the engine speed is of much use in a truck, except for bragging rights in drag races. Give me that torque around 3000 RPM where I can do some useful work and I will be happy.
By the way 380 lb-ft of torque is 1.15 lb-ft per cubic inch and that is a very decent number. Full on race engines can make as much as 1.4 to 1.5 lb-ft per inch when on the cam but any streetable engine that make 1.1 to 1.2 lb-ft per inch is doing extremely well.

My stock h/c/i/short-block 4.6 4V makes 1.22 lb-ft per cubic inch at the rear wheels, or about 1.38 lb-ft per cubic inch at the flywheel assuming a rather conservative 12% driveline loss. It also gets 23 mpg on the interstate taching ~3,000 rpm, makes 276 lb-ft at 2300 rpm (at the wheels), idles like a Lincoln, and loves to rev. Not too shabby for an engine most people say sucks (n/a Modular).
I understand the anticipation but when Ford say it I will believe it. Ken has said it before. Ford has told nothing about it. They wont let some internet blogger ruin thier number.
So my guess is nice round numbers.
Alot goes into truck performance than the engine numbers. Tranny and gearing are more important.
I drive a V10 with 3.73 and the so so 4100 tranny. The engine has a ton of torque but struggles getting it tot he ground. My company chevy 5.3L with deeper gears actually has better drivability. The V10 has gobbs of torque but the setup is the weakest of ford offerings. My V10 4.30 DRW dump body is just right. If it was a torqueshift 5 speed tranny it would be perfect.
Give me a 1/2 ton truck with in the 300's in HP and close to 400 in TQ with a nice 5 speed and 4.10-4.30 gears and I am in love. 4.30's are a longshot from the factory but I have 4.10 are not. My dads doge with 3.92 are perfect for his truck. So 4.10 would be even better. Engines run better with abit more RPM in them.

my guess is 365 and 400 for the 5.4 witch is PLENTY

If they are just going to drop the 5.4 later why would they spend a bunch of money to give it a huge increase in power like that, when the 6.2 is on the horizon. I wonder if the 4.6 will benifit from these alleged huge increases.
I think no matter what the power/torque increase turns out to be, the performance is going to be greatly improved due to the new 6 speed auto. With first gear ratio of 4.17:1 second gear 2.34:1 third gear 1:52:1 fourth 1.14:1 fifth .87:1 and sixth .69:1, i am predicting near tundra levels even if they are 40 hp short!!! I am by no means a ford fan but i am not blind to smart engineering. Way to go ford.
