New 4.6L 3V photos

[rurumon]

Stop me if its a repost, but since it was just recently added to BON, i figured you all hadnt seen it yet.


sweetness, get me some of that (http://www.blueovalnews.com/2003/cars/mustang.05.463gt.htm)

[jgc61sr2002]

That's one cool looking engine.:up:

[woaface]

Looks like it's got some balls! I wonder if that thing could sit in a Marauder...!?

(That way of thinking has worn off on me...)

[Macon Marauder]

Yeah I saw that puppy on BON last week. Would love to see some specs.

It's not really that big of a deal. It's basically the 5.4L 3V heads (from the 2004 F150), stuck on a 4.6L shortblock. Since it has the same deck height as the 4.6L, fitting it into the Panther platform shouldn't be a problem. But- the better question would be, "Why bother?"
The 4V engine will still produce more HP. But, what you really WANT, is torque. And, for that, you need longer stroke. The 5.4L would be the better choice (and the 5.4L 4V Navigator engine SHOULD have been what the Marauder came with). Problem is, with the 25mm higher deck height, the larger-displacement engine won't fit.
Now, bolt on a bulged hood, maybe with cowl induction, and it'd work...

So these heads aren't VVT, then?

[rurumon]

i thought the only reason they went with the 3v instead of mounting the old 4v was cost. It looks like they are keeping all 3 options just to create more options.

[Macon Marauder]

Not interested in it for Panther platform personally. But in the 'Stang. It's got to have more punch than the 2V, right?

[TJH]

No VVT yet on modular engines- the 3V is an attempt to get more power without costing as much as a 4V engine. With respect to the F150 5.4L 3V, while it is a smooth and capable engine, the performance is not what I would call earth-shattering. The Dodge 5.7L Hemi flat out kicks its butt (and sounds pretty darn sweet doing it, IMHO).
As for pure appearances, I don't think the sheer size of the 4V cam covers can't be beat. I mean, they really look like they belong on a late-60's hemi. Now, I still think our Marauders should ahve come withe them powder-coated silver, however...
What the 3V engines DO offer, is better emissions. No, nothing as exciting as performance, but better NOx and HC numbers.
The EPA is pleased. And perfomance enthusiasts couldn't possibly care less...

Our new 5.4-liter, 3-valve TritonTM engine provides more of the qualities our customers love in a V-8 engine - plenty of power, with instant gratification when you push the accelerator pedal. To this, we've added a new level of smoothness, quiet operation and efficiency. It's the best of all worlds."
- Pete Dowding, Manager, Modular Engine Programs

5.4-liter, 3-valve TritonTM V-8

* 3-valve design - All-new three-valve cylinder-head architecture is designed to enhance both power and efficiency.
* 300 horsepower - Combination of engine technologies produces 300 peak horsepower - a 15-percent improvement in peak horsepower over the previous 5.4-liter engine.
* 365 ft.-lb. torque - The 5.4-liter TritonTM V-8 boasts a 7-percent improvement in low-speed torque, and 5 percent increase in peak torque, to 365 foot-pounds.
* Torque advantage - Low-end torque is higher than competitive non-heavy-duty pickup truck engines.
* Variable cam timing - Variable intake camshaft timing provides a broader torque curve, better response, improved efficiency and reduced emissions.
* Electronic throttle control - The segment's first torque-based electronic throttle control yields a smooth, consistent response.
* Refined sound - Carefully crafted sound quality and reduced noise, vibration and harshness stem from a tuned intake resonator, a tuned low-restriction exhaust system and other improvements.
* Upgraded transmission - A new 4R75E automatic transmission handles the impressive torque output.

TJH, the engine does have VVT. The 3 valve head flows just as well as the 4 valve head at a lower cost.

I don't know if you guys have heard a 3 valve 5.4 triton v8 uncorked with a performance exhaust, but it may possibly be the most beautiful sounding v8 engine in the world. The melody that motor makes is an art within itself, and I just couldn't believe my ears. While the older 2 valve 5.4 v8 sounds almost like a big block with a deep throaty exhaust note when uncorked, the 3 valve 5.4 motor has such a unique and exotic sounding note. It still has a very deep sound, but it sounds so even, clear, and melodic. It's a pure symphonic orchestra going on under the hood, sounds like unlike any other v8 i've heard. I imagine the new 3 valve 4.6 motor will probably sound similar, although the 4.6's exhaust note is going to be hard to beat. The new 3 valve 5.4 has reaffirmed my belief that Ford makes some of the best sounding v8's on the market!

Sounds good to me also...:)

[Billatpro]

Of most interest to me is the cast iron exhaust "Headers" not equal length perhaps but when was the last time you saw an exhaust manifold this sweet?

[TJH]

My contacts at engine indicated that the VVT was axed for cost reasons. I'll check into it further after the holiday break.
Sorry, as for big V8 sound, NOTHING beats a traditional Pontiac V8 (preferably 455). That would mean, of course, nothing after 1979, in terms of an actual Pontiac engine (and not the GM corporate engines that came later).
Now, of only you could legally run any of these newer engines uncorked, without having to worry about pass-by noise certification...
Ah... to dream...

[junehhan]

:(

That's a shame that the VVT was axed for cost reason's on the 4.6 as it probably would have had incredibly potential with it. I guess it's understandable as I can understand why it wouldn't be very cheap on a v8 motor. However, I imagine that as competition heats up in the future, and as EPA restrictions increase, VVT will probably be something that eventually will happen. Either way, I can't wait to start seeing applications with the new 3 valve motor! I just hope it produces decent power...............

What is WT?

[joflewbyu2]

The engines do have VVT. The F150 have it on the 5.4. Being a modular engine, the 4.6 will eventually get it as they run out of the older 2 valve head. VVT (variable valve timing) was invented by honda (vtec) and used in formula 1 racing instead of turbocharging for durability reasons as well as simplicity and cost savings.

V V T is variable valve timing

[Fourth Horseman]

So I'm assuming there is one larger intake valve and two smaller exhause valves?

[joflewbyu2]

http://www.mercurymarauder.net/foru...=&threadid=6858 Fourth Horseman, READ THIS FOR INFO !! 2 INTAKE AND 1 EXHAUST

[Fourth Horseman]

I'm not getting anywhere with that link, but thanks for the info on the valve configuration.
