O.K. boys, its great to hear all the ego's bouncing around this forum. But the reason I joined is to find out what perf mods actually help this damb truck to beat my old 460 or at least come close to it. I am a licenced auto tech, also heavy duty off road tech. There appears to be nothing wrong with this 2v v10 compression wise, does not consume oil, is low km's on entire truck. I would like to know what chips help these engines if any, cause I heard they don't work in the v-10, and I don't like wasting money finding out. Are headers and exhaust worth the effort? I have 3.73 gears in this underpowered slug. Has anyone had same set-up and switched to 4.10 gears found it of benefit? Help is needed hear boys cause I hate it when I get passed going uphill by a freakin hemi pullin a heavier load than I am.
Also, anyone who is not pulling heavy loads at hiway speeds up big hills need not reply, cause clearly your experience is not valid! Towing around town with your little work trailer loaded with dirt at 50km/hr does not test the ability of your truck, for some of you who have such reply's.
Does anyone have dyno results to share as a result of their performance mods????

 

Gears must make a big difference. Mine is all stock but has the 4.30:1 gears. I pull stuff like this all the time (7,000 lbs all the way up to about 18,000 lbs in an almost 8,000 # Excursion)















Oh, and this Excursion WAY outpulled my 94 F-250 with the 460 AND gets about 1.5 mpg more with the same load.

 

Oh boy, well, you can come sit with me on the "other side of the room" since your about to get jumped on by all these blind V10 lovers that think it's the best thing since sliced bread. Gets the job done, but any truck can get the job done. From everything i've gathered, not many if any mods really do a thing for the engine, except gears...pizz and moan about the truck being a slug and right away you'll be told you need to spend the $1000+ to swap gears, V10's love to scream and they should have a minimum 4.30 gear with stock tire sizing to work right. Either way, welcome to my helll and prepare to laugh very soon

 

AOD or manual trans? 3.73s suck plain and simple, I have them in my truck and they are all right for empty highway but thats about it. If you have stock size tires 4.30s would be a better choice. Headers an exhaust were worth it for me but to some it may not. Good luck finding dyno info on headers/y for the V10 besides the Banks powerpack. A tuner helps power even when running 87, the higher octane the more the spark can be advanced and the more the power. The main benefit is a good tune allows WOT fuel enrichment which makes more power. There is some dyno info in the sticky in the V10 forum but its on a non PI v10.

If you do a seach here in the V10 forum you will find answers to most if not all of your questions.

 

I'm not sure you'll get the response you are looking for that way.

So instead, you can find a ton of great threads using the search tool (above). The guys on these forums have awesome advice (timeless, in fact!) about pulling over the highway with the V10 and every performance-related tidbit you'd ever want to know.

One trend you'll likely discover: Gearing makes all the difference in the world.

 

240_gordy, one other thought I had...

Considering the power/torque/curbweight differences between your 2v V10 truck and a similarly equipped modern dodge hemi (most extreme case), it isn't too unreasonable that you are getting beaten while pulling the same load.


- Your classic 2v V10 gets around 310hp/425lbft.
- The modernized Hemi-powered Dodge HD gets 390hp/407lbft.
- On average, the Dodge is 400-600lbs lighter than an equivalent Super Duty, while your older truck equipped with the 460 (92-96 vintage?) is probably the lightest of all three.

 

Unsubscribing from this thread would help immensely

 

Well I think my experience is valid, I scale at 24K and I have pulled all over the country (coast to coast) including Alaska and some of the highest passes in the CO. The only mod I have on my truck is a Banks Cat Back exhaust system, it helps in the high altitudes but the flat lands I really can't tell much difference. I have also pulled with EFI and non EFI 460 motors, the EFI was not impressed with but the one I built for my 1981 truck pulled great but it was heavily modified with 4.10 gears. But there was no way that truck would out pull my V10. Your problem is you have a F350 with 31.6" tall tires (265/75/16) and 3.73 gears I have 30.4" tall tires (215/85/16) and 4.30 gears. If you don't want to change gears then that's your problem not ours. I bought my truck new and made sure it was ready to pull from day one or it would have never left the lot. If I was to buy a new DRW today it would have 4.56 gears form day one because of the tire size change in the newer trucks.

O.K. fellas, at least now what I am reading is a little bit more help, thank you, it is apreciated. The dude with the excursion all loaded up impresses me cause you obviously have the 2v engine as well, and the pics are the only way I would believe that you know what your talkin about. So now I feel like there is something I can actually do with this truck. I have spoke to Ford and a local gear center, they both say that I have the 10.5 ford rear end and the dana 50 front in this 1 ton. They also say that the lowest gears offered for the ford 10.5 is 4:10, but I was hoping to get the 4:30 gears instead. What diffs are required to get the steeper of the two? Also my truck is the 4spd auto, any history of trans trouble if pulling in O.D if the truck will do it? And yeah I upped the tire size from 265 to 285 cause the truck sits so high factory and looked silly with the smaller tires so I can only blame myself for part of this I guess.

 

I pull with mine in OD all the time.
If it feels like it is straining, shift it down or get in the gas so it kicks down.
I have the same gear problem.
They make after market 4.30s, but if do not know much about doing that.

 

The 2000 F350 came with only two gears options 3.73 and 4.30. I think the dealer and others are thinking F250 that came with 3.73 or 4.10 gears. If you are going to stay with that size tires I would look at 4.56 gears (after market).

you sure? my 99 was 3.73 or 4.10 , no 4.30.
I would have got the 4.30s if they had them!

 

Gears for the Ford 10.25 rear can be used in the 10.5 also with the right install pieces. You can get Ford gears in 4.30, 4.10 and 3.73 for the 10.5 rear. The D50 and D60 have a lot of gear options also. You can regear your truck down to 5.38 gears if you so desired.

Not sure about the 99 but in 2000 3.73 and 4.30 in the F350.
