HORRIBLE design
I've seen more than a handful of those heads line honed with bearings installed.

First of all it's called line boring... And secondly I wouldnt trust the design line bored with a bearing because I don't even trust the original design... So once again the motor is one giant POS

I had a 2003 F250 with 5.4 and 6 speed manual. Loved it, got good mileage (about 16 average highway) and worked fine to tow with. One of there best features is they produce a high percentage of peak torque at low RPM. Had a 3.73 rear end so if running at 55 would have to shift down on long or steep hills but seldom had any need to downshift if kept it at 65 mph. Mostly towed a large cargo trailer I used for work, about 9000 pounds and about 11 foot tall, kind of like towing a sail. Only reason stopped driving it was got a company truck. Friend of mine has a 2004 F250 with about 230k on it with a 6 speed as well. He has replaced his clutch and plugs / coils but that is about it. I'm in the market for a V10 F350 now, can't see driving a 6.2, don't believe I have ever owned a car / truck that had to drive at greater than 4k RPM for more than just a moment. On the 6.2 at 4k is just starting to wake up from what I've read.

5.4 up to 03 was and is a good built motor. Virtually indestructible unless you are an idiot. Once they started the VCT in 04 that when things went downhill. Trying to adjust the timing with a lock/unlock pin that is determined by oil pressure. Hence the diesel sounding 5.4 3V's. About $600 to fix the cam phazers but no, I agree this motor has no place in a F250. My Expedition is a wanna be F150 that can't get out of its own way.

New to the 5.4's.... I've had superdutys with 7.3's for over a decade, but just did some trading for a 2000 F250 CCSB lariat 5.4/auto/4x4. Long term, I plan to swap a complete 7.3/6spd drivetrain into it, but will need to daily drive it for now, until I'm ready to do the swap, likely about a year. And, my oldest boy (17yo) has expressed some interest in it as well, maybe I give it to him as-is.

I've read this thread from the start... some of you like the 5.4's, later model ones are not as good, is what I've picked up. My truck has about 240k, new plugs and coil packs by P.O., needs an exhaust and tires, but is in good shape otherwise. I plan to go over it, change fluids/filters, but what else should I be looking for, particular to these motors?

On a 2v 5.4, nothing. They're stupid reliable.

I would pay attention to the timing chains, after a while they can stretch and get a little play in em. I could start to hear mine slap the guides a little so I changed em before it had a chance to jump time (220,000 miles about). Put in new oil and water pumps while I was there. 2002 5.4, it's been a turd in terms of speed but it's never let me down

1999 F250 Supercrew LB
MBRP 4" straight pipe
S&B
PHP Hydra
Edge Insight CTS2
Sweet IH Steering knob (adds at least 1000HP)

Finally got the truck referred to in the above post on the road... rebuilt rear leaf springs, swapped in another used trans, exhaust, 315 tires and fender flares, and been driving it for about a week. Seems to run ok, has a vibration at cruise speeds... need to check u-joints. Need to change the oil soon.
