Ford 6.2L Official numbers are out

[Extreme4x4]

And then there is the Nissan Titan, toothpick rear axle. LOL

Sorry, I just had to............... it's so cute.

^^^Oh god lol dont get that titan crowd in here haha! I tell you what they really think those trucks are invinsible i tell ya, i must admitt its a great truck for nissans first full size truck (particully the powertrain) but it has some issues that owners still fail to admitt or even acknowledge.

But they all have there little problems.

It's better than the Tundra's glass frame now isn't it?

My whole point is that there is a reason the Hemi doesn't use the 8.25" and the 6.0 doesn't use the 8.6".

The GM designed 10.5" 14 bolt is atleast the strength of the Dana 70. The pinion support is awesome on those axles.

I gotta say the the AAM designed carriers aren't nearly as beefy looking a comparable Dana or 10.5" 14 bolt.

Doesn't GM still use Dana 60's in the Express vans? I'm looking at an '07 3500 with a 60 right now.

Dodge does not use the 8.25 in fullsizers. The 9.25 is standard.

BTW, AAM builds the 10.5 14 bolt.

Some minor variations aside, such as the Express and export markets, here is some data to compare:

GM 8.5 early: 28 splines, 1.20" dia axle shafts; 1.625" dia, 30 spline pinion.
GM 8.5 late/8.6: 30 splines, 1.31" dia axle shafts; 1.625" dia, 30 spline pinion.
GM 12 bolt (truck): 8.875" RG, 30 spline 1.31" dia axles; 1.438" dia, 30 spline pinion.
GM 9.5 sf: 33 splines, 1.47" dia axle shafts; 1.86" dia, 30 spline pinion.
GM 10.5 FF: 30 spline, 1.56" dia axle shafts; 1.75" dia, 30 spline pinion w/ 3rd bearing support at nose.
GM 11.5 FF: 30 spline, 1.56" dia axle shafts; 1.75" dia, 30 spline pinion w/ 3rd bearing support at nose.

Ford 8.8: 28/31 spline, 1.32" dia axle shafts; 1.625" dia, 30 spline pinion.
Ford 9": 28 spline 1.20" dia shafts, or later 31 spline, 1.32" dia shafts; 1.31" dia 28 spline pinion gear.
Ford 9.75 sf: 34 spline, 1.37" dia axle shafts; 1.969" dia, 31 spline pinion.
Ford 10.25 FF: 35 spline, 1.50" dia axle shafts. 1.94" dia, 31 spline pinion.

Chrys 9.25: 31 spline, 1.32" dia axle shaft; 1.876" dia, 29 spline pinion.
DANA 44: 8.5" RG dia, 30 spline, 1.31" dia shafts, 1.376" dia 26 spline pinion.
DANA 60/1: 9.75" RG, 30 spline, 1.30" dia shafts; 32 spline 1.41" dia shafts; 1.626" dia 29 spline pinion.
DANA 60HD: 9.75 RG, 35 spline, 1.50" dia shafts; 1.626" dia 29 spline pinion.
Super DANA 60: 10" RG, 35 spline, 1.50" dia shafts; 1.626" dia 29 spline pinion.
DANA 70: 10.5" RG, 32 spline, 1.41 dia shafts; 1.75" dia 29 spline pinion.
DANA 70U/HD: 10.5 RG, 35 spline, 1.50 dia shafts; 1.75" dia 29 spline pinion
DANA 80: 11.25" RG, 35 spline 1.50" dia shafts or 37 spline 1.6" dia shafts; 2" dia 37 spline pinion.

So, these numbers only tell part of the story. Look at the 9" and compare. The 10.5/11.5 AAM axles have a 3rd pinion support, much like the 9", and hence why they appear weaker, but are not.

I along with other silverado truck owners, know how well these engines work (even more so with the new 6spd) and really this is no discussion man. I mean hey real world vs. your opinion??? I know which ill choose from.

I hear my customers all the time and believe me ive pretty much heard it all, and the majority trade there 5.3 silverados in for another 5.3 silverado. Again i think ill side with real world situations rather than speculation.

Some of you people really dont understand the potential of these engines, few has yet to realize it. Were talking about some of the best engines in the world here. Take it or leave it.

Haha, and nailhead 425 i agree with you 100%. Though im guilty of towing alittle over 9,000 with my 02. . .Yeah i know i need to get me a 2500 but god that 02 has just been so good to me.

Re the towing and 3/4 ton comment... Thats another debate but short answer your right.

Speculation Hmmmm. Here is some "real world" info for ya. The reason so many GM truck buyers buy the 5.3 over again is due to the reputation the pre-07 6.0L had as being the all-time gas pig. I know many GM drivers some on their second 07+ model and these guys continue to buy the 5.3L. I ask em why and they tell me about their bro in law or friend that had a pre-07 1500 HD with the 6.0L and how much gas that thing used. I try to tell em the 07+s were much, much better with no success. My best friend has a 07 V-Max and he agrees, everyone thinks he's on crack for buying a 6.0L. (never mind what he had to go through for the dealer to find one) Yet he goes on a long trip with other 07, 5.3 also 4.10s and guess what, the difference in fuel usage was laughable. Almost no diff. But no one believes it.

And again I'll state the 5.3L is a good engine. But not in a truck. Dos the 6 speed make up for some of its weaknesses... Yes. But guess what, the other tourquier engines all got 6 speeds now too. (ok not the SEMI-HEMI)

[frenstall]

Awesome numbers but... where's my F-150 diesel???? I want it I want it I want it. I'd take a silverado 1500 diesel too. Let the competition begin! Common Ford/GM, there is a reason why the majority of HD trucks are diesel, why not move the same formula down to your smaller trucks????? mmm... torque+fuel economy = happy

All ill say to that is if your a person thats "serious" about towing, who cares about gas mileage? Exactly. Point proven. Now can we stay on subject.

Many folks do. They tend to drive diesels, as diesel tend to have less variability in fuel economy with additional weight.

EcoBoost 3.5L F-150, Torque and Fuel economy you want, without the expensive fuel, excessive oil capacity, and high level of required maintence the Diesel has (fuel filters, DEF fluid, for example), oh and I forget to mention, several thousand dollars less money.

All trucks died last summer with fuel prices. As gas prices droped, buyers ran right back to the poor fuel economy vehicles. I'd say F-150 is near the same sales it would have been without the fuel price, however, Diesels have never recovered. Every week we are forced to order Diesels because Ford has run out of gasoline engines for the week due to higher demand than supply. The reasons are many, but diesel trucks no longer pencil out for many buyers (still make sense for some) that were buying them before. If you knock out the commercial use trucks, our diesel sales are probably 30% of what they were 5 years ago. People towing a camper on the week-ends or hauling livestock on the occasion they don't have a semi-load aren't buying diesels like they used to, and are going with gas engines.

With the modern diesels being emisions choked to death, they aren't getting the fuel economy advantage they used to. Also the used market is saturated so the resale isn't like it used to be. We also used to have no problem getting high mileaged Diesels financed, the banker looked at them like a semi-tractor where 100,000 miles was just broke in and would do them when they wouldn't finance a gas. Now its the opposite because of the high cost of repairs. Diesels cost so much more in repairs that many of these used buyers can't afford to repair them. Compare the cost to put a water pump (or injector, or any little sensor in the engine) in a 7.3L Diesel to putting one in a 5.4L or V10, then you'll understand why the bank now is more friendly to gas trucks.

Sorry, but I see no future in the US for diesels, unless emmisions laws are relaxed or a new technology makes it easier to clean up emmisions and return them to the fuel economy they used to get. Oh, and before anyone says its just the 6.4L that doesn't get mileage, its everything. Go to www.fueleconomy.gov and pull up a 2010 VW Golf diesel. Fuel economy is 30 city and 41 MPG highway. Compare that to a 1985 Escort with a very low tech engine (not even a turbo), 5 speed transmision (6 speed in VW) and the Escort comes out ahead with 36 MPG city and 46 MPG highway (converted to new EPA ratings, sticker in '85 was 43/52). Makes you wonder what a non-emmisions equiped diesel could do with all the new technology if it were available.

Wow your "logic" is baffling! Thats the best you could do?

[SDDL-UP]

The 5.3L Chevy can't do the WORK of the 5.4L Ford - Sorry! The 5.4L Ford is a much better truck engine IMO.

Now to the issue at hand... the Ford 6.2L Boss!

I'm a little surprised at the numbers, or actually where the peak numbers are, 411 HP at only 5,500 and 434 lbs.ft. at 4,500 (higher than I expected). All on fairly low compression 9.8:1 and regular gas to the Chevy 6.2L (L98?) at 10.5:1 running premium. The Chevy actually makes it's very impressive 417 lbs./ft. at 200 RPM less than the Ford. I want to see a dyno sheet for sure!

Out of the box the BOSS looks like a powerhouse for sure. Total power under the curve? I think this thing will have a TON of potential. The pictures of the combustion chamber show a lot of room for larger valves in the 2V configuration.

Let the games begin!

Everyone welcome yet another ford enthusist to a GM website. . .If you couldnt tell already

Haha, nice way to start introduce yourself i see your on your 2nd post . But anyways. . . .

[SDDL-UP]

Well I figured maybe a different point of view might be appreciated. Wow... you've got over 1,700 posts and I got you all worked up with just my second post? All for suggesting the Ford engine might be better than a Chevy! LOL!

WRONG!

If you want to fit in here i suggest you fall in line. Everything Chevy does is better than Ford.
