6.2 v 5.4
I pull a 28 foot travel trailer and cant even use 6 gear and only getting 6 mpg with the camper.
The V10 has so much more power. If i could find the last year they had the V10 in the F250 i would trade it in. TODAY

I have a 2012 with the 6.2 in it. Traded in a 2003 with a V10. Wish i had that F250 with the V10 back.

I went from a 2000 V10 (same as your 03) with 4.30 gears to a 13 6.2 with 4.30 gears and I will take the 6.2 with the 6 speed any day over V10 with a 4 speed.
If you want help to make your 6.2 a better puller there are a lot of us on the 6.2 that will help.

6.2
Are you getting 6 or 7 mph pulling, on another post you said 7.
I went from a 2000 V10 (same as your 03) with 4.30 gears to a 13 6.2 with 4.30 gears and I will take the 6.2 with the 6 speed any day over V10 with a 4 speed.

I checked on a Super Chip. Was told that it wouldn't do any good in the 6.2. He wanted to sell it to me but i would be bringing it back. Not sure what i can do. It has a 100k warranty. So if i do any thing to in they could drop the warranty.
With the last V10 i could chip it but not this one.
I will take any help and info.

With the 6.2 from I have read you need to look at 5star tuning. I can't speak from experience yet as I'm in the process of buying a 2012 with the 6.2. I haven't pulled with one but they seem to have good power driving around. I would guess you have 373 gears as not many seem to have the 430 gears.

I will check out the 5 star tuning.

It's more than just rpm when you compare 3.73 to 4.30 it's the difference in the mechanical advantage you get with the lower gears were the rubber meets the road, all the tuning in the world will not make up for it. Another big difference maker is tire diameter when you are looking at power delivered to the road. Flywheel HP and torque are great to know but its what gets delivered to the pavement that counts.
I used the dinomometer results that Mike at 5 Star had for both the 2V V10 and the 6.2 to compare the two before I ordered ours. The 6.2 runs a little higher rpm than the V10 did but the peak was close to the same at the rear wheels. I was also ready to have 4.56 gears installed if I wasn't happy with the 4.30 gears. To date we have 14.6K on the truck and 10K of that is pulling our trailer and I'm very pleased with the truck, we gross at 24.4K loaded on the road.

I hope you are able to make your truck work well for you.

I would likewise suspect that you are running the 3.73 gears as opposed to the 4.30s. I spent a good long time looking at 2008-2010 trucks with the 3V V10, but I couldn't find what I really wanted, which was a CCSB with the V10 and a Manual transmission. I had to think long and hard about going to an automatic transmission. When I decided that it would be okay to do so, information regarding the huge improvement from the 5-speed to the 6-speed transmission convinced me that a 2011+ truck with the 6.2 and 4.30 gears was going to be the way to go.
I hope you are able to make your truck work well for you.

The local gear shop I trust charges a bit under $500 per axle, that's out the door parts and labor for a gear swap.
Like Denny says above though, if you're going to do this then match the gears with the expected weight you're going to haul and the tire size you intend to go with. In some cases you might be better off with 4.56's.

Had a hard time finding where this was posted but I had put it in my notes for future reference. I hope this helps.
6.2l swap
vehicles 05-10 you can use the cam positioning wheels and have them made to fit the front of the cams and use the factory sensors.
crank trigger wheel made for the front of the balancer. engine harnesses 4.6l and 5.4l should lay on top of the 6.2l using sensors. you may be able to splice factory 6.2l with factory 3 valve harness. pauls high performance has done this.
vehicles 97-04 cam sprocket CNC'd to match factory cam position wheel and sensor. crank trigger wheel needed on front balancer. harnesses lays on top of 6.2l
before 97 you can use factory engine harness/PCM
PCM $350-$780 harness $230 disable trans and body harness functions.
6.2l shares the same trans bolt pattern as 5.0l 4.6l 5.4l and 6.8l
stock truck intake manifold would be best if used in F150 F250 F350 swaps with cabled 80MM TB.
sheet metal intake manifold will be needed for car swaps.
the factory 6.2l PCM uses drive by wire like the 5.0 uses.
Livernois make cam phaser lockouts for the 6.2 along with a very expensive stroker kit to make it a 400 ci engine. This setup described here is basically to trick your factory computer into thinking it is running the 5.4 then tune for the added displacement and larger injectors. I read where one was swapped into a crown Vic and the guy made it seem like it wasn't a big deal, but he was banned from the forum so I was never able to get the full details. I would love to do this to my 2003 f250 4x4 as the 6.2 has proven it has a lot of room to grow in power production, but I will do good to have enough time to get a 5.4 built and swapped in place of my current 5.4.

the easiest swap are in the 90s through 2003 and 2004 model ford vehicles.
pretty much everything will go right up to the 6.2l. your biggest problems are the crank trigger and cam shaft reluctor wheels.
there are several people who spliced 3v harnesses with the factory 6.2l engine harness. again this is something you need to look at with the swap vehicle harness and the 6.2l engine harness and you need to know the factory PCM pin outs.
also the 6.2l and 5.0 do not use ECT so that function has to be set off.

Thanks for all the info americansteel. There is certainly not enough info on this swap from people that have done them. I do not have time for all the little headaches so i am doing a built 5.4 2v with trick flow heads for my truck. After it craps out then i will go built 6.2. Do you have any pictures of the swap?

BTW trickflow heads are am waste on your motor. You can easily get 435hp@6000 rpm with ported pi heads. but if this motor is going into a super duty you better think otherwise on what you really want.
