OT Kind of,,, Ford 6.2 VS GM 6.0.... pulling

Have a 2011 GMC HD3500 6.0 and 4:10 gears and pull nurse tanks to goose neck with 15,000# load or so. I am looking at a 2015 Ford F350 with 6.2 gas and 6sp auto and 3:73 gears. Can you guys give me your thoughts as to which might be a better set up. Ford has an option of 4:30 gears but I think that would be great for power and bad on mileage or maybe not enough. Thanks
 
I'd sure go for the 4:30 gears. You'll never know the gas mileage difference. Note that overdrive on the 6 spd is 0.68:1. That's pretty high. My 08 Ford has 4:10 with the older 5 sp torq-shift with the .68:1 OD. The engine is still at a very comfortable speed at 70.

The mileage is going to be terrible on a big gasser, at least gear it low enough to have power. That's my opinion anyways..
 
Had 2003 Chevy 2500 XC/LB 4x4 6.0 4spd Auto 4.10 gears
295 hp, 360 lbs/ft

traded to

2011 Ford F250 CC/SB 4x4 385 hp 6.2 6spd Auto 3.73 gears 385 hp, 410 lbs/ft

Pulling the same trailer with a GCW of 15k, the Ford's doing it with greater ease and getting better mileage as well.

Went from 7.5 - 8 mpg to 10 to 11 mpg pulling same load. I no longer feel as whipped after a days haul with the 6.2's extra power and two more gears to choose from.
 
Pull similar load on a bumper pull trailer with a 2001 5.4, the low hp 2 valve motor with 4 spd and 4.11's. I would suggest the 6.2 will play with that load whichever gears you get.
 
I will just add this, I have removed quite a few sets of 373 and installed 410s and lower for guys with 3/4 and 1 tons over the years, those higher gears really suck power when you really NEED power. I have 410s in a 1 ton and would not want anything higher.
 
funtohunt, The new 6 speed Tranny has been a Game Changer in the bigger pickups IMO. You are better able to stay in the power band,& RPMs too.
In My opinion the type of topography will determin your rear gears, Flatland 3:73, for rolling, hills 4:30s, Chances are the OD slot each way will get you better economy at highway speeds. Are you pulling more or (No Trailer) Empty more???
I will add..........
I hope it is a 4x4 truck, WITH Manuel shift lever in the floor and Manuel Hubs!
Why??????
When getting a really heavy load moving you can Leave the Hubs in Free!
shift into the Low Side of the Transfer Case and Essentially double your rear gears on the low side 2to1, 2 engine rpms IN to 1 rpm Out
The transfer case can be a essential tool on your truck. drive till you get up on good hard surface Road!
You can use the Low Side of the Transfer Case, 1-5
Shift Tranny into N.
Let off the Gas
Gently But Firmly shift T.C. Lever to Hi position shift Tranny into D, Reapply power, Tranny will seek it own reentry point as to speed and Drive on!

NOTE the above description will Not Work with the automatic shift knob on the dash System!!!!
Call me if You like and I will be glad to visit with you! My # is 512-577-3837!
I do Not think you will go wrong either way.
If the Dealer has 2 trucks Identical to each other except for Gears then a bumper pull Test at some heavyer wt will help answer that ?? for You!
Hope that helps!

And buy your rear axle shafts a dozen at a time. There is a valid reason that the manufacturers don't provide a 2-Lo position.

Willie, The reason there is No 2Lo Position, is It is accomplished in the 4Lo position with your Hubs in Free. Cheaper cost to build Trans-Cases!
I have been using my 4x4s in this manner for 25- YRS on Numerous Ford Trucks! I have never had One problem at all.
Back then we had to negotiate the sideways U in the TC shift Pattern! Now it is a Straight Shot!
No hold up and loss of rpm, speed issues!
The Neighbor who put Me on to this was using his trucks a H3LL of a lot harder than I ever did. Bigger and Heaver Loads. IMO this is a sometimes deal pulling 15000 lb trailer for him! Or He would had said so! If that is the case He really need to Looking a F-450/F-550 if this truck is doing this Every day!!! Even for a F-350 You are Getting-out into the outer regions for day-in/day-out work.
Unless You have been doing this then Quile in!
I am simply showing him how to the the Most out of his Truck. Stock Version, No Fancy, High $$$ Modifications!
The reason Crap breaks is the Operator Gets into a Big Hurry, goes to Snatching and Grabbing and applying Waaayyy tooooo much Power at the wrong time and things go south in a hurry. Usually that How thing get broke. I was doing this with a 3/4 4x4 chevy pulling NH3 tanks, an old 80 model I had at the time!

I ordered just such a truck last week... 4x4 with lockouts and manual shift transfer case, 6.2, 3.73s, 8' bed.

I am most excited about getting the vinyl floor. Trucks shouldn't have carpet. I wish I could have got a manual transmission, but it seems they have went the way of the dodo bird.

The rebates and dealer discounts made ordering this one a better deal than any used one I could find in the last 6 months.

Last I checked the only pickup that still has a stick is the cummins Ram.

Not even the one-ton gas ram.

That is what I found too. A few problems with the Dodge... First of which is it is a Dodge, second was they only offer a Crew cab and a Stupid big cab, no extended cabs... an 8 foot be is mandatory for my use, a Crew gets to be pretty unmaneuverable with an 8 foot bed. Both the Chevy and Dodge have boxed frames with lots of holes down the side. I live in the snow belt, boxed frames have a history of rotting in short order around here(stacks of frames in the Toyota dealer parking lots)

The other issue is cost, the Diesels are a 10K upcharge, even if it were free with recent fuel prices, the math doesn't pencil out.
 
I run mostly in fairly flat to rolling area most of the time -- 80% or so. But when I pull to some of our other farms 100 mile away, there are some pretty good hills to pull.
 
you going to pull much with it. Also with the lockouts and floor shift, do you still have to deal with the traction conrol/advanced trax button to get more throttle when you are needing your 4wd in mud or snow?
