Engine changes?

I heard that they were dropping the 4.6L V8 for something more substantial. And I also heard that the hp numbers on the gas engines were going to be raised quite a bit to be more competitive with C#$&* and D*@!&. Can anybody verify these rumors and if so, what is the new engine going to be?

In truck trend they said that ford is working on a new 5.0L and that they are keeping the other 3 engines to.

why can't they go for something with better gas mileage and horsepower. When the modular was designed even the engineers weren't sure it'd make a good truck engine because they weren't supposed to be, but i guess to save money etc. it was a last minute deal?

But, also an '08 Mitsubishi Lancer GTS. (sorry, traded an '02 Ranger in on it; gas sucks guys!)

i think u were refering to the modular 5.0L to take the 4.6L place...what ford really needs it another inline 6, maybe with around 250hp and 400lb tq at around 2000rpm and none of that modluar $h*t. if they did if sell mine ASAP and get one...or at least a crate motor LONG LIVE THE I-6

????
I could be wrong of course, but I've heard nothing about the 4.6 being dropped. The 5.4 for sure and probably the 4.6 will get three valves per cylinder. Supposed to make slightly over 300 horsepower. (5.4)
Not sure where the 5.0 rumors came from. The only 5.0 speculation I'm aware of is for the '05 Mustang.
And what's up with all the modular motor bashing?? Have you even driven one?

yup and hate em. ford needs to concentrate on making a good looking truck and not adding another valve..

That DOHC 5.4 from the Navigator would sure be a nice option. 300+ hp would make the trucks and expys move much better.

personally im a fan of about anything ford makes.. but im diehard... I love the modular motors... Ive never drove anything that run any smoother and they get good gas mileage.. really good for a 4x4.. at least my 4.6 does... ill admit.. it could use about 35 or 40 more ft lb. of torque.. hopefully they will take care of that... and I disagree with a truck not suppose to be fast.. my 78 ford with a 68 model 429 will sure as hell get the job done and it will sure as hell run to... to me what makes a good truck is one like the new fords.. they are tough, ride good, drive good, quiet inside, get good gas mileage, and good power.. but I think they could use a hair improvement with power...

ok let me restate myself, i also am i diehard ford fan but im not big on modular motors. my 300 6 will run just as smooth as any mod motor and i wansnt talking about older trucks or trucks that u build for speed, i mean people who intentional buy a truck with high hp and thinking they are a god. and when it comes time to off-road its a major terd. i myself wouldnt mind a 68ish f-100 with a 351C and a 4 speed :-staun can u say fast

When the modular motors were first introduced I was one of their biggest critics - I wasn't impressed with them at all, and thought that Ford had made a big mistake.

However, now that I've owned one for a while I've changed my mind - I've been really impressed with the 5.4L in my '02, and for towing and farm chores I think it is at least as good as my old trucks with the 300 I6 or 351m...and not much worse than my 400 (back when it was stock, of course). And I'm talking about work (pulling trailers, hauling loads), not racing and that sort of thing.

As far as the new 3v motor goes, I noticed that the torque peak moved from 2,500rpm up to 3,750rpm - and that worries me. I'd like to see the torque curve on the 3v plotted against the torque curve on the 2v, and see just how much it has changed in low RPM range. More horsepower is always nice, but it isn't going to help me pull a load...I prefer not to tow at 5,000rpm. My truck is pretty darn quick as it is, and I really don't need to be able to compete with sports cars.

Oh, and from what I've heard recently Ford's bragging rights with the 3v aren't going to last long - Dodge is planning to offer the Hemi as an option in their half-ton trucks, which is currently rated 345hp and 375 ft-lbs. However, the torque peak is way up there at 4,400rpm...so it looks like a high-rpm screamer rather than a useful truck engine. I haven't driven one, but if/when I do I'll certainly be testing to see how much low-end torque it has.

Next time I buy a pickup (probably '04 model year) it's going to be a tough choice between an F350 with the 6.0L PSD or the new F150 with the 3v 5.4L...a lot of it will depend on the F150 redesign. Either way, I'm looking forward to it! I hope they still offer the 7700 with the new F150...

ya, thats what i was trying to say, needs the torque down low. hp is great but wont do squat when it comes to pulled when the peak TQ is like 4000

Don't worry about the current engine's torque vs. the new 5.4l 3v in the low rpm range. 90% of the peak torque is available from 2250-4750 rpm, which would mean you're making over 325 lb-ft through that range. The 350 lb-ft at 2500 rpm (the max the current 2v stock head makes) may also be made by the new engine around the same rpm. The engine will still have the same torque down low, it'll also have more torque spread across the whole power band!!

Makes me pumped just talking about it.

>for work....not to go fast unless its a lightning.

Exactly. The old pushrod motors made torque..and gobs of it. THAT is what you need in a truck. I don't give a crap if a truck makes 300 horsepower or not. I'm not planning on taking it to the track. What I want to know is can I pull a trailer without having to stay in the 4000 RPM range? A pushrod motor will do that. An overhead cam motor won't.

Perfect example: My '99 Ranger has the old pushrod 4.0. I only make 160 Horsepower. The new Rangers have an overhead cam 4.0. They make 207 Horsepower. That is 47 MORE horsepower....sure makes the new 4.0 sound a lot nicer, right? But the truth is, if you look at torque numbers, you'll see that there really isn't much difference at all. My truck will pull a trailer just as well as a new Ranger. And it will do it at LOWER RPMs, which reduces wear on the engine.

If Ford were smart, they would revert back to the pushrod design. That way, they could get all the pulling power they need, and by putting the powerband at lower RPMs they could likely engineer the engine to acheive better fuel economy too. The old engines were hard on gas because at the time fuel was cheap and no one cared. If Ford would have just perfected the fuel consumption rather than scrap the whole thing for "mod motors" they would have been better off.

AMEN!

I'll even take it with 200 hp and 300 ft lbs. And none of this overhead cam stuff. OHC is not needed in low rpm engines.

INLINE SIX POWER! '95 F150 XL
300 Cubic Inches of Low RPM Truck Torque! And twin-I-beams too!
