There must be something wrong with your truck if you had three people in it and at almost full throttle still had no power...... My GF dad has a 2000 F150 super crew 5.4 tow package so it's 3.73 gears and he has almost 210k as of last week and that thing will lay posi burnouts all day long, he tows his 26 ft stripper boat all over with no problem and it has more than enough power for messing around or merging onto the highway. Now my 04 F350 in my sig now had 4.30 gears and I tow a small 30hp backhoe for work, my 20ft CC boat on a dual axle trailer plus once a year I load my 8k dual axle utility trailer with fresh cut wood for my uncles wood stoves and my 2valve 5.4 has plenty of power driving around margin into traffic and for messing around. Would I like a V10 of course I would but my 5.4 has done everything I've asked of her and has never let me down EVER

Three valve motor is the same block just different heads and a slightly different intake. Spark plugs are same locations etc etc just different heads to flow better getting you the extra forty horsepower. 260vs300 BUT the 3valves have that problem with the two piece plugs, and them ridiciouls cam phasers that go and bang and clunk

When I had my '08 V10 I did the plugs myself in 90 minutes. I was in no hurry and took my time, if i had to do it again I could do it in a hour. It's an easy engine to work on. I also had a 2000 V10 and the '08 had a lot more power and would easily outrun the '00. So I would highly recommend the '05-'10 V10's and if you can get one with 4:30 gears. It will bring a smile to your face.

My 99 F150 has 3.55 gears with the 5.4L. Pretty much economy gears. Just the thing I don't like about 4.10 or even 4.30 gearing is because the RPMs will be higher at highway speeds. I just looked up the 2 piece spark plugs...holy crap! $10-$13 for just 1 plug??? I can see why people have to buy a broken spark plug wrench. I would not be looking forward to spending $104-$130.
What was the motor upgrade for the 2000 model year?

And 4.10s don't really affect rpms to much. I sit ~ 2500 at 65-70

Are there much of anything for say dual wire plugs for the 3 valve trucks? Something like the Bosch Platinum+2 Spark Plugs Platinum+2 Spark Plugs

Just for thought but I went from a '00 f250 (2V-260 HP) SC LB 4x4 w/ 5.4L 3.73 rear. It towed and hauled what I asked but slowly. Upgraded to a '06 F350 CC LB (3V-362 HP) 4x4 w/6.8L 4.10 rear. Tows and hauls 10k with no issues and wayyyyy faster than the '00. Even better with a Tuner from Mike @ 5-star! Two totally different animals though, the front coils were an improvement for turning radius but the ride empty is still a bit harsh. As far as working on them I believe they are about the same IMHO. I just did the plugs and coils within the last few months. I changed them out at 70K in fear of the seize up potential. Follow the directions on how to and its cake. Just remember these rigs are heavy. I scale in at 8k empty with no trailer and just a few things in the tool box. Don't expect Lightining 1/4 mi. times. These trucks were meant for "doin *****". Both trucks got about 10-12 mpg all around driving on a tank of 87. Hope this helps ya a bit. Good Luck!

I'm not one to go for racing. Though it is tempting and I am guilty of racing a few cars off the line but that's rare in itself with the price of gas. Trucks were meant for working not sitting on a freakin trailer. I was checking out prices and there within a few grand of each other. Newest I may end up going is 2010.

Just trying to weigh the cost to do the maintenance between the 2 valve and 3 valve. Other than the plugs, everything else seems to have stayed the same as far as maintenance. $10-14 for plugs vs $3-$6 for plugs. But its only every 100,000 miles or so that they are changed.
