03 Ford V-10

[RyanbabZ71]

Ok at work I have driven 3 different 2003 ford trucks. All were 2wd crew cabs with the V-10 and the same rear ends. 2 were long beds and 1 was a short bed. 2 had about 24K miles and 1 had 40K miles. I cannot for the life of me figure out why each of them drives different. You can light up the rear wheels on the 40K mile truck (long bed) and on the other 2 the engines are sluggish. None of them even feel remotely the same when driving. I have driven a handful of 5.3 trucks and they all drove almost exactly.

 

Any ideas on why this is? Tolerances of the engines real big so some are powerful and some are not?

I dont know much about the 6.8 V-10 .

( wheres hillhound?? )

But I can tell you that the 7.3 and 6.0 haul ass in the F-550s weighing 17k

My grandparents Winnebago E450 with the V10 sure doesnt have any problems getting up and going.

see thats the thing 1 of the 3 has some get up and go the other 2 are so-so with power

Maybe the engine has to be broken in.

My 4.8L Silverado does that, sometimes it feels awesome, like I could whip anything. Other times it feels like something is restriciting it, not sure if its a change in temperature or humidity or what.

I've noticed that a lot too in my 4.8. I think a lot of it for me is due to outside temperature. During the night or a cool day things get much quicker than in the middle of the afternoon when I feel like the 4.8 might stand for cylinders

[RyanbabZ71]

its not a it has power today and not tomorrow 1 truck has lots of power all the time and the other 2 are lackluster all the time not just certain times

Same transmissions?

 

Could have been what Truckman said. Some engines are just different from others as well.

Do they put the torqshift behind the v-10s ??

That could be the differnce between the old 4r100 and the torqshift

Been hunting in KY for the past week and just saw this post.

 

Ford only offers that Torqueshift tranny with the 6.0L diesel (for what it's worth).

 

I dunno why those V10's would run differently, Ryan. Mine has 3.73s and it will burn up the rear 285s on dry pavement in a heartbeat. Nothing slugginsh about it. I do know mine ran alot stonger and got better mileage after about 1500 miles of break-in.

 

Only thing I can guess is that maybe there's some maintenance issues, especially with the amount of miles on them for being just '03 models. Maybe a dirty fuel or air filter or fouled up spark plugs? I've driven mine and a few others and they all felt about the same. One of them I drove was a '99 and it was slower but the '99s were rated for less hp/torque than the 00-03s.

I've seen alot of dyno tests that show engines dont really run their best (power wise) until 40,000+ miles. Usually this is just 5-7hp difference depending on the powerplant. I doubt this would make this much difference though...
