5.4 #s are in... FINALLY
#46
Can't really argue with anything ya said here...
What I meant by shortening the life, was based on the 5.4 platform. By cranking up its HP numbers, making mods, and tuning it for maximum HP gains, will shorten its life span. The high compression, the high torque loads, the higher strain on the drivetrain and the entire truck in general just take its toll far quicker.
Would I be mad if Ford went with a new engine ? Heck no, and eventually I think they will drop this modular motor, and go back to a more traditional gasser, or better yet, introduce more diesel options ( )
I wouldn't mind running a 6.5 or larger engine, having the bigger HP numbers, but I also want Ford to stay true to it's "Built Ford Tough" and being one of the hardest working, longest lasting trucks out there. To crank up the HP numbers, just for the sake of having higher HP.... I guess just isn't for me. I like the "real world" power the Ford provides.

Pickup truck online is doing a test on half tons that is due out in about 60 days I think so it will be interesting to see the results of all of the half tons. Bet you a cup of coffee that the 5.4 will get smoked towing and not towing and will suck up just as much gas as the others. Tow ratings are just that. I think they are pencil whipped by Ford for bragging rights. They do have the best frame ect but lack the raw power under the hood. They have gotten better so I will give them that. I would just like to see Ford more competitive with powertrains. They do well against the GM 5.3 but that is not their top dog. See my point?

I would rather have a better built truck than an extra 20% bhp. This is why Dodge's, Toyotas and chevys feel so cheap and dont last like the fords.
Im not convinced that a Ford will last any longer. Im also not convinced a Chevy will last any longer. Some of it is just luck of the draw. If you take decent care of them and dont beat them up everyday then I think they will all give good service over the long haul.
My brother in law just sold a 93 f150 with a 300 six in it with 260,000 miles of pure neglect and abuse. His workers used it and after the first six months it looked like it came out of a junk yard. They beat this truck to death in everyway possible and they could not kill it. The oil seldom if ever got changed and when it did it was with some off the wall el cheapo stuff. It got to leaking oil real bad at the end but ran like a top. This is what I wish we could expect but I know he just got lucky. He has never got a bad Ford, Chevy, Dodge or anything else. Some people are just lucky.
If it was raining *****s I would reach down and pick up a *****. Thats how my luck goes.

320 and 390 is really not that bad, considering this truck is going to be lighter and have 2 more gears to work with. Besides, there are a lot of new engines on the way.. ecoboost, 4.4 diesel, 5.0 v8, possibly BOSS....

You make some valid points no doubt. My question is why do you assume that a higher hp engine will not last as long? Im not being a smart a@@ by asking by the way but somehow I have my doubts about this. Sometimes, you can take a smaller engine and work it to death and it will die early simply because it didnt have enough power to begin with. Would a 4.6 last as long doing the exact same work as a 5.4? It has to work harder so I doubt it would.
I understand there are limits to each platform and what they can reliably produce powerwise. Honestly, I have never been impressed with Fords mod engines. I think in mustangs and crown vics they are fine but I have always had my doubts in the back of my mind in the trucks. Mind you, I have never owned on in a f150 either. Personally, I think the GM small blocks are bullit proof as you get. The seem to do better on fuel as well but they do have to be revved a bit higher to reach peak power and the torque curve may not be as flat as the Fords now.
I understand peoples frustration with ford being so short on hp. They honestly are not competitive at all there but they did find some nice gains in torque. They have squeezed the 5.4 for all its worth and they just lack the cubic inches to get anymore out of it. I often wonder if they could do it all over again if OHV engines would not have been a better choice. GM has done ok with theirs.

A 4.6 doing the same work as a 5.4 surely will be more stressed and possibly not last as long.
But compare a completely stock 5.4 engine vs a 5.4 engine with a canned programmer and an aftermarket intake. These engines are notorious for running lean with aftermarket intakes, and a canned tuner often leans out the engine even more for extra power. Sure the modified engine will have more power and possibly more ease doing work, but it will fail quicker than the stock engine too. The engine is designed for stock parameters for a reason, and Ford seems pretty damn good at nailing these parameters, as their engines are known for lasting a long time...even if being worked hard.
As for GM small blocks being bullet proof, i agree they are good engines, but not as good as Ford's. My family has 3 chevys: a '77 chevy with a 350/5.7, a '98 chevy with the redesigned 5.7, and an '03 with the 5.3. I can tell you that my 5.4 3v has been/is a lot better than all of them. Power wise and reliability. The transmission that chevy decided to put behind the 5.3 is absolute garbage, and it seems u-joints are constantly failing. The engine is only part of the drivetrain, to be reliable the whole package has to be "bullet proof."

I agree with you and I am an old guy. Trucks are not made to be fast, but that doesn't mean that they have to be slow. I really enjoy having a truck that can get out of its own way when it needs to.
#53
Honestly, so would I. Mixed with the lighter frame, and all around lighter model, i thought the MPG's were gunna shoot up a couple more then they did.
Oh well, still stoked to see how these trucks perform, real life testing that is.
#54
Lighter frame?
Not really something I want to hear about in my trucks. They are supposed to be beefy & durable first! Chances are pretty good that if they are made lighter, they are not going to be as durable. I thought Ford made the right decision with the stronger (and heavier) parts put into the 2004 and new models.

Look into it a little bit first.
Its actually lighter, AND stronger. With today's metals heavier doesn't always mean stronger. They used a different material, and formed it in a different way I believe, to make it much stronger, and at the same time, shed a few pounds.
They also claim a higher use of the "high strength steel" then previous models. So, it will be lighter, have better crash ratings, and be all around stronger.

"For those thinking that the '09 F-150 is just a skin-deep redesign, you'd be wrong. The entire platform is new and boasts a fully boxed frame made of hydroformed high-strength steel. It's lighter and stronger than the current platform, so expect payload and maximum towing numbers to increase when they're released on Sunday."

Yes this is true. the 5.4l in the 09's is ment to produce a more TQ low down than the other brands. Which should make it better for towing the larger loads. Esp with the new 6 speed box.
