Even if it is increased it would only be a very small increase and would have little to no impact on longevity. Think about it, any gas engine turns more RPMs than any diesel out there and they last 300K if you take proper care of it. Add to that the 6 speed tranny and they can afford to go a little higher because they can have a lower 1st gear.

Your right. I don't know, when I see that much HP, I just can't see it lasting as long as say, a 7.3L. What RPM would this motor have to run at to get that much HP? I guess we will find out how things turn out pretty quick.
They have a 6.9 coming out?

They didn't. Development was just moved from the US to Australia...[/QUOTE]
Are they really doing that? I hadn't heard that, I thought Bob Lutz just axed the whole thing. It makes sense though. Just because you guys get ALL the fun stuff!! (With the exception of the 426 hemi)

The 4.6l I don't think could EVER work in a traversely mounted setup.
That is a phenomenal amount of power and torque going through the front wheels of the Impala.
In acceleration I have no doubt it would do quite well, and as a tourer (and I suppose this is US's primary requirement) it could win some friends.
Chevy obviously did quite well to mount a 5.3l traversely, but (and I know this is a big call without driving it) in my opinion the package is fundamentally flawed.
I have NEVER driven a front wheel drive vehicle with more than 200hp and about 180lb ft that I could genuinely call a complete car. And some of those vehicles have had the most nifty devices to try and quell torque-steer - Focus RS for example had the most advanced Diff I think that was ever fitted to a production car, you would still put the foot down at 40mph on a slightly damp road, attempting to overtake a truck, and not be sure whether you are going to overtake on the left or the right.
Was an interesting experience for sure (and an intriguing car), but I don't think I could call it pleasurable.

Some useless trivia.........the 4.6 Ford was originally designed for FWD duty. The motor while wide, is actually decently short (no wise cracks) One knock of the mod motor was it uses very narrow main bearings to achieve the shorter length. A lot of "experts" predicted, wrongly, early crank failures. As mentioned above, the Continental not only used the 4.6 but it was a detuned DOHC 4 valver.....260 HP I believe.(the bearing/FWD info was garnered from BON years ago)
On to high HP FWD's........Caddy used/uses a 300 HP Northstar (DOHC 4 valve 4.6) in their front wheel drives.........I'm not sure if they are still available with Caddy's new found love for the proper wheels driving the car.
Ford, of course, had the kewl SHO Taurus with 220 HP V6's and 245 HP V8's (both Yamaha motors)driving the wrong wheels.
So while we get to droooool at the Aussie hardware we can't get, +200 HP FWD cars aren't all that uncommon here.
Almost forgot; have you ever heard of the Caddy Eldorado or Olds Toronado?
Back in the day these monster had 500CID and 455's that were close to 500 pounds of torque............and they were FRONT WHEEL DRIVE

If I had to guess, I'd say about 10-20% of current D-Max owners are running that kind of HP right now. 
The upgraded Allison should help the transmission live longer though.

DOHCmarauder- the DeVille is the last of the Northstar driven front drivers from Cadillac, and '05 is the end of the line for that model. It'll be replaced by a DTS RWD in '06.
On another note, the STS-V is waiting in the wings, with a 440 HP Northstar mit kompressor. 0-60 in about 4.8 seconds, 13.8 quarter, 165 mph top end. not bad for a 4300 lb luxo sedan.

DMAX-HD I'd venture to say it's even higher ...
Which, the HP current owners are running, or the percentage of them running it? Sssh! What's interesting is you'd think we'd have Allisons flying apart right and left, but so far so good (knock on wood).

The car bizz thought process is soooo strange IMO. I always thought of Chevy (and Pontiac) as the performance arms of GM. NASCAR, drag racing etc.
So GM gets rid of all hi perf RWD platforms for those two divisions, except for the imported GTO, and makes Cadillac ,in essence, the performance division with all the cool RWD platforms.
Now Chevy gets a hot Impala...............but as BigF is alluding to,a HiPerf FWD is not my first choice with all that is available now(most notably Chrysler)
BTW, I read where GTO sales are perking up..........special deals or people are finally dicovering 400HP RWD coupes for around 30K are
?

Are they really doing that?
Well I rode in a Zeta development car a couple of months ago, with an engineer from GM I am good friends with.
The car (Holden Commodore - the 4 door sedan which the Pontiac GTO is based) will be in showrooms in the 2nd half of next year.
It has been delayed quite a bit, but from the car I rode in, it will be worth the wait.
As for the Duramax: They have a 6.9 in the wings?
So I can assume that will have more power than this 6.6?
By jeez...
I know the intial release of the 6.4l PSD was going to have less power AND torque than the 2006 Duramax...
And then they are bringing out a new one!!! OUCH

I spose it is just our respective markets.
Australia has a HUGE aversion to anything above about 180hp that is FWD.
In small cars, anything over this number has to be AWD.
In larger cars either AWD or RWD is acceptable.
