I noticed that in the new 2004 F150 to be released this Summer that they
have the 5.4 liter Triton up 40Hp to 300Hp and the torque was up 15 ft/lbs
to 369.  They now have 3 valves instead of 2.  It's hard to tell without
seeing the torque and Hp curves, but this engine could finally be viable.  I
wonder if it lost it has already lost it's chance forever ?

Ford Australia is using the engine in our latest XR-8 Falcons, with either a
3 or 4 valve head. 300 HP for the 3 valve & 355 for the 4 valve.

Any torque curves available?

Historically going from 2 to 4 valves has typically reduced low end torque
in favor of mid to high end torque with the improved breathing not really
helping until higher rpms.  The torque curve is everything in ski boats.
What gives me hope is that they did this in a truck that needs torque and
that has cats, etc.. with more intake and exhaust losses.  At 300 and 369
they are within shooting range of the Gt-40's  without modification.
Marinized I'm sure it would be right in the fray with at least 330Hp and 385
or better ft/lbs of torque.  Of course this still doesn't mean it would be a
good marine engine or better than the current Chevys, but the numbers look
about right.

They look like Ayres Rock, 500Nm for the 4 valve which is 260kw or about 370
foot pounds of Torque.

(Ayres Rock is that big Red thing in the middle of Aus That the Tanned
poeple have now renamed to Uluru)

I thought it was the follow-up to "Midnight Oil" <G>  You know, some
us actually have been to Oz <VBG>

And is "tanned people" the PC term for Abbos?

Progress yes but they've just about wrung out all that block has to offer in
naturally aspirated form.  The 3v heads also have variable cam timing.
Can't recall torque curves but it's still SOHC and therefore nice and
wide...  I'd rather see the Hemi come to market than the 5.4.

Holden still manage to wring a bit ( quite a bit ) more out of the older
pushrod 5.7 though... Still manage to lead in power, torque, handling, sales
and braking.. I don't understand the sales part, when, to be honest, neither
the falcon or the commodore are great cars, and the reliability of them is
shockingly pitiful beside either their European or jappa counterparts. (
citing the Maxima and Avalon for the lower cost bracket )

There is still this little problem of engine width.  Measure a 5.7L, or even
a 6.0L sometime.  Then get a longer tape and give the Triton a go.  Folks
won't like what it does to the space inside a tourny boat.

NOT the showroom floor model, ie SS is only 235 kw, & they don't have that
much torque
& they don't really handle. (Isn't Trailing arm suspension VW Beetle Stuff &
Double Wishbone
more from the Jag camp <VBG>.
