    Stopping/maybe fixing body rust if I decide to keep my current Expedition?

    There is no excuse for the rocker panels, Ford used crap steel with poor drainage. It usually starts around the 4 year mark. I don’t think the kickers offer much safety. In a side impact I doubt my brand new F-150 fairs much different than my old rusty Expedition would have. They are tin foil...

    Engine swap

    Regarding 5.0 swaps because probably the most common…There are also many generations of 5.0L F-150 engines with big changes. Many things are not interchangeable between generations. Gen 1 - 360 HP/380 LB FT PI 10.5:1 compression Gen 2 - 385 HP/387 LB FT PI 10.5:1 compression Gen 3 - 395 HP/400...

    Engine swap

    Looking closer the 5.0 will not fit dimensionally in the Expedition chassis as the chassis is modified and not as wide as the F-150. Now we have our answer on why Ford never offered it in these, she don’t fit.

    Engine swap

    Only decent option there is the 5.0 and Whipple, the 7.3 isn’t as stout as the 5.0. 5.0 has a closed deck with steam holes and a forged steel crankshaft versus an open deck on the Zilla. Your cheapest bet is just tune your existing engine.

    303a but with 304a hp/tq added??

    Non efficient heads with restrictive ports.

    303a but with 304a hp/tq added??

    28 psi for 540 HP is not great

    Safety Thoughts on New Gen?

    They added those crash bars in the F-150 because the Supercabs did poorly in the 2015 launch IIHS testing. The Supercab went from “poor” to “good” in the all offset overlap for 2016 so they make quite a difference in protecting the cabs integrity.

    Any Crazy Things To Look Out For On The 5.4L 3v Timing Job?

    Oil pump pickup tube bolt was tough. I was 21 when I did mine so my hands were still smaller or boyish or whatever LOL and it was still hard. Maybe have someone smaller ready to try and get those bolts if you have issues. I ended up bending a 8 mm I think it was in the vice to fit the angle...

    2014 or 2017? And why?

    The lockers are nice, enjoy the one in my F-150. My Expedition EL did great with open diffs though, never got stuck and took it through some semi-serious off road. Sometimes I almost would prefer a limited slip on the new F-150 as the 5.0L V8 is quick to light up the rears with 400 Horsepower...

    2014 or 2017? And why?

    It’s not a bad idea to do a timing job on a 5.4 as it will be a 10 year old truck, I’d figure that into your cost if you can’t verify it’s been done. Be sure the engine has been previously maintained though (oil changes etc) and start it cold to verify no nasty rattle. Like I said, the timing...

    2014 or 2017? And why?

    As these are both getting old the 5.4 is the winner, you can engineer the problems out of it. Throw some cast iron tensioners in the 5.4 and you have a reliable foundation. The 5.4s Achilles heel was the tensioner blow outs starving the top end. These aging EcoBoosts are much more tricky and you...

    2025 ford expedition redesign

    I love the 5.0 V8 in my F-150, probably my favorite option I selected on the whole truck. Only thing I’d trade it for is a hybrid 5.0L. I just don’t think motorheads tend to buy the Expedition as we do with pickups and pony cars. Idk if the demand is there in an SUV.

    2025 ford expedition redesign

    Expedition R with the 5.2L V8 to match the Raptor R, one can dream

    2025 Expedition details

    Headlights look very similar to current GMC Sierra. The taillights look exactly like the GMC Yukon. Wonder if Ford is buying the lighting package from GM.

    Phaser Noise after replacement

    Did you use OEM Ford VCT solenoids? The aftermarket ones are famously bad out do the box and will struggle to run the phasers. Exhaust manifold was another good suggestion.

    2008 Ford Expedition stuttering while driving at 40-50 mph

    If you have a 2007-2008 with the 6R75 the solution I found is shudder guard (product attached). I replaced the torque converter with a brand new Ford unit in my 2007 back in 2020. Also swapped ALL new Mercon SP into the system. After another 1.5 years it started to shutter slightly again. Put...

    hub actuators again

    Are you sure it’s not the IWE solenoid? Located on left side of fan shroud. Very common failure and will have you chasing ghosts that aren’t actually the hubs.

    5.4 roller follower failure

    If the other items were done recently I’d replace all the roller followers and move on. Your oil pressure reading is OK at hot idle. Not superb but not indicative of an issue either. Are you running 5W-20 or 30? 5W-30 is fine for the 5.4. No chain slap noise or rattle on start up right? The...

    Hybrids Confirmed

    The 5.0 V8, Hybrid, and 3.5 EB are all rated an identical 24 MPG highway for a 4x4 on a 2024 F-150. The hybrid doesn’t help on the highway, it’s 500 pounds heavier. That is just dead weight on the highway. Generally my V8 does better on gas than my cousins Hybrid on the highway by a half mile...

    Engine choices?

    A lot of OEM engines are octane limited these days with the higher cylinder pressures. For example, the 5.0L V8 in my 2023 F-150 is running a 12:1 compression ratio (this is the same compression as the Ford FR9 NASCAR engine which runs race fuel). You can see in real time the ECU pulling timing...

    Moving on....

    Sounds like me, I very much enjoyed both my 3rd gens and still log in here and there. However, my 2023 F-150 with the 5.0L V8 has been so much more fun, 400 HP/410 lb ft of torque and she shifts at 6,800 rpm in sport mode. The new 5.0 is more of a T-Rex and the 5.4 was more of an Mammoth. The...

    Dial Shifter - Let Me Vent!

    I like the setup in my 2023 F-150 STX. It’s got the column shifter and a full center console. The STX is a rather basic trim, I optioned the center console, locking axle, and 5.0. It’s one of the hacks of this trim, yes the center console is an upcharge….but you can get it and it keeps the...

    rear differential locked

    Not a surprise given a true locker does not excel on pavement, it is really for when you have severe axle articulation etc. Ford probably figures the use case of the F-150 (being on job sites etc) needs a “go or no” condition vs the in between. To be honest the Expedition is just better in snow...

    What to do??

    Ford really screwed the pooch on the King Ranch Expedition getting rid of the two tone paint. Can that even be called a King Ranch? Lol. My vote is the stealth

    Thinking of supercharging the 5.4 2v

    I’m not saying he can push 800 HP out of a 5.4, my only point was hyper pistons hold up just fine to boost. Both the 3.5 EcoBoost and 5.0 V8 run hyper pistons in their stock form. If he keeps boost in the tolerable range, the engine will live a good life on high octane fuel.
