So you don't consider nearly 400HP out of 330 cubes serious power????

And even if you're correct on the cost factor, it seems the Japanese have no problem keeping DOHC/4valve motors in their trucks.
A pity though... A VVT 4V would be nice
I am sure it could more than keep up with the .6-.7l with the respective GM/Mopar designs, whether it would be a good alround motor on the other hand (my 5.4l's have a tendency for appreciating susbstantial quantities of gas for instance - which admittedly has a lot to do with my right foot, but still...)

I must say I am disappointed. Not because that Ford may bring the Hurricane back. But the bias I see here for OHV designs. At the rpms ranges we run our trucks or even most cars a OHC is less effiecent than a OHV unless we are going to using variable valve timing, DOD or a multi runner set up. Without those being part of the design what you gain in controling valve timing events you lose in parsitic loss by having to run 2 cams.
The other thing is that in the case of GM I think they are going to move away from the big displacement V8 and move into the supper charged arena. They are going to do this to meet the newer MPG standards that are coming down but still be able to provide big HP and torque numbers. You don't need a big hp motor for everyday driving and in fact need very little in the way of power to run down the freeway at 70mph.
It will be interesting to see what Ford brings to the table with this motor. Will it be as effecient as the LS series motors or will it be as gas hungry as the Hemi's?

The BMW V10 is sorta getting at my whole point.........Ford has basically the same architecture (DOHC 4 valve) Now they're re-tooling for an entirely new powerplant.
I know the torque mongers are going to pipe in....but do me a favor and check the weights of some of these German/Japanese land yachts, then look at the times they run 0-60.....1/4 mile etc... Torque coming in 1000 RPM or so higher aint nothin' a good 5 or 6 speed trans and lower gearing can't fix!!
My Maurader is an excellent example....some say it's a slug off the line because of the of lack torque.....I say BS, there's V6 mini-vans that weigh the same with less torque/hp that are as quick if not quicker.
It's the total package(s) that need to be addressed.......not just throw more cubes at the problem.
But I do look forward to the specs of the Hurricane.

Negative....it's the motor available in Australia at the moment....and Fred (Big350) stated it puts down about 20 more RWHP than the LS6......
Who's spanking whom????

Or how about the LS7?
we didn't put a limit on didplacement did we? After all these are still the best the big 3 offer. I know about the supercharger 5.4 haveing tons of power, but anyone and their mother can get big power with forced induction.

Are you reading any of this thread???
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.

They will bring out a completely new engine every 5 years...

Not versed on the European market......But I do know that the success of GM and the aftermarket is directly related to interchangabilty and length of production.
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 only serious GM engine that makes decent economy while making respectable power is the 5.3L and thats only if you compare it to its two gas guzzeling competitors (fords 5.4 and Dodges 5.7).
Now take the LS series used in the cars from Chevy. We know the Vettes exceed the mileage figures by a long way, even the LS7. The GTO is close but it might have to pay a little tax.
FYI to get out of paying the tax the vehicle must get 22.5 combined.

We have heard about the vette exceeding the mileage limit, I believe it has more to do with gearing, weight and drag co-efficiency more so than anything else. And yes, GM engines are fairly efficient that helps too.
As far as the Charger, I believe on the high end it is rated at 25 with the 5.7 Hemi, 29 with the V6. That 14/20 is for the SRT8.
My sister in law just bought one this week with the 5.7 so I can let you know what they get, second hand, if you are intrested.
The only thing I am concerned about for the 6.2l ford is emmisions. I see the over head v-8's not doing so well in the green house listing. I believe the 5.4 F150 is like 5 on the list, the 4.7 dodge is also in the top 10 twice for the ram and the durango.
