Its back...Hurricane!
The 5.4 is only down 35 or so HP(389, I know I said 400) with nearly 40 cubes less.....I believe that with a few tweaks (like VVT/Variable runner lenghts) that ain't no hill to climb considering the potential of a DOHC 4 valve head (see comparo's to Japanese and German motors)
Since some people are worried about piston speed (rightfully so) how about Ford buliding us a long rod shorter stroke motor with the tall deck 5.4 block...like stated, BMW can get 500 HP out of 5.0 Liters N/A.
"I know about the supercharger 5.4 haveing tons of power, but anyone and their mother can get big power with forced induction"
Since one goofy comment deserves another, here's my gem of the day;
I know about the 427 cubic inch LS7 having tons of power, but anyone and their mother can get big power with 7.0 liters....
At the risk of being redundant, I look forward to a 6.2 Litre Ford........but as is usual with Ford, they tend to abandon designs/products that have LOTS of potential left for the sake of change or perceived economics.
Even the LS(GM) series of motors 4.8 through 7.0 have probably more interchangability than the Ford MOD motors ( the 4.6 MOD motors from Romeo and Windsor factories have MANY different parts.......from valve covers to cranks)
Give me ANY reason to change bellhousing/trans mount patterns from the 302/351 to the MOD motors???
How about different input shafts from the FOX body to SN95 cars(Mustangs) EVEN though the underpinning were indentical???
I just wish Ford would stick with something and stop acting like their engineers are tweeking!!
The fact that Ford doesn't utilize their superior head design for their trucks may be a good reason to abandon the OHC.
Why Ford only lets there truck motors have 260 or 300 HP when the 5.4 is capable of so much more is Ford's continuous way of screwing things up.
And please don't start with the torque stuff.......I'll take a HUGE gamble and say those Aussie motors with near 400HP have as much torque down low as the truck motors by 2000 RPM.......Fred????
BTW...........you're being sued. I'll settle for 1 BILLION dollars..
Not quite (unfortunately)

VVT would help a lot though...
I found these;

The 2V peaked at 2000RPM with 278#
The 3V had 260@2000 but peaked at 300#'s @3900
My W.A.G. is your 4V will be very close down low but carry an extra 30+ #'s at it's peak which I'm guessing is not that far off the 3V's 3900RPM.

(remember we are in metric)
From the graph (remember this is an engine dyno, not a chassis dyno like yours...)
At 2000 it looks about 435Nm (320lb.ft)
Torque peaks at 4500 with 520Nm (382lb.ft)
So, taking into account an estimated 20% loss:
@2000 = 256lb.ft
@4500 = 306lb.ft

Not quite what I was expecting....
I'm basing a lot of my "thoughts" on Navigator performance since all 3 motors have been available; 2V, 4V and now the 3V.
Strictly from memory, when the 4V replaced the the 2V the Navi gained 40 high end HP with about 10#'s more torque higher in the powerband....but it GAINED a nearly 2 second advantage 0-60.
The 3V seems to have a very close powerband to the 4V but the Navi LOST a second to the 4V!!!
Give me the HP a DOHC 4 valve is capable of and gear it CORRECTLY any day over a motor that runs out of breath quickly.
I will always concede that at the power #'s that Ford tunes these truck motors to, that OHC seems to be overkill (especially the old 2V SOHC)
One revelation that kinda blows my mind is that IF this Hurricane makes it to market by, let's say, 2009.........the MOD motors will be 18-19 years old!!!

Is your fule milage really much better than your 7.5L? Cause my 5.4 sure isn't much better than my uncles 96 460.

Good point.
But the problem, IMHO, is Ford doesn't use their best version in the trucks.....with the exception of the V10.
Here are Ford's BEST MOD motors;
320 HP DOHC 4.6..........more than a match for GM's 4.8
390 HP DOHC 5.4 from Oz....would stuff the 5.7 hemi and 5.3 GM. and I really believe with more tweaking could run with the GM 6.2 and 6.1 hemi.
The V10 equals and surpasses GM's 8.1 (I realize the 8.1 is old school) while giving up 1300CC or 80 cubic inches!!!
I know the 5.4 in a Super Duty is kinda overmatched but I rarely got double digit MPG in my 460 where I regularly get low teens with the V10 (have heard the 5.4 is aprox. the same)
All I've tried to say this whole thread is Ford has the guns to compete.....for whatever reason, they choose a different more costly route....as is their usual M.O.

PS. The fuel mileage is about 50% better with the V10 over the 7.5L. I would struggle to get 10 with the 460 and get 14-15 on a regular basis with the V10. I have gotten as good as 16.5mpg (It was hard driving that slow).
