Chevy vs. Ford in Heavy-Duty Rumble in the Rockies

Over the summer, we published the results of our nine-truck Heavy-Duty Shootout, where we selected the Chevy Silverado 2500 HD and GMC Sierra Denali 3500 HD as our two top picks in the three-quarter-ton and one-ton diesel categories. But our readers raised two important points.

The first point was that we didn't test Ford’s "Job 2" engine calibrations for the all-new 6.7-liter Power Stroke V-8. The free powertrain software update for 2011 diesel Super Dutys boosts the ratings from 390 horsepower and 735 pounds-feet of torque to an astonishing 400 hp and 800 pounds-feet, eclipsing GM’s 6.6-liter Duramax V-8 rating of 397 hp and 765 pounds-feet. We didn't test the re-rated Ford trucks because they weren’t available at test time.

The second concern was about the quarter-mile and hill-climb acceleration tests, where we measured performance over relatively short distances pulling 10,000-pound and 12,000-pound trailers. The tests were enough to provide consistent evidence of the strength of GM’s powertrain, but some thought Ford’s diesel and new six-speed would have beaten the Chevy and GMC if the distances were greater.


We didn't disagree with these two points and wondered about both ourselves, even though we know our Shootout comparison tests are the most rigorous exams you’ll find to judge pickup truck capability.

The challenge

Then, in late September, Chevrolet challenged Ford to a real-world showdown in the Colorado Rockies, similar to the Mike Rowe head-to-head towing competitions that Ford has used to promote the capabilities of its F-Series pickups. Ford declined, but the bowtie boys decided to press forward and invited and Diesel Power magazine to witness the test.

We agreed with a few conditions: Chevrolet had to use test trucks purchased off the lot from Chevy and Ford dealers and the Super Duty had to have the 400/800 power ratings. They couldn't come from GM's captive test fleet and the trucks had to be as "apples-to-apples" as possible when it came to features and equipment. While Chevrolet originally wanted to test three-quarter-ton HD pickups — the heart of the HD market — we had to use one-ton trucks because that was the only way to match equivalent rear axle ratios of 3.73. We also had to drive and instrument the trucks to measure the results ourselves. Chevy reps would be along for the ride.

Chevrolet met those conditions, and we picked up two brand-new dealer-bought HD pickups in Detroit. The 2011 Chevrolet Silverado 3500 LT four-wheel-drive crew cab came from Mike Savoie Chevrolet in Troy, Mich., with 8 miles on the odometer and 0.9 hours on the engine meter. The "Job 2" 2011 Ford F-350 Super Duty XLT four-wheel-drive crew cab was sold at Harold Zeigler Ford Lincoln in Elkhart, Ind., and driven to Detroit by a third-party fleet service. Two Diesel Power staffers drove the trucks 1,250 miles to Denver.


How equivalent were the trucks? They were probably the most evenly matched HD pickups we've tested. Besides the same rear axle ratios, the $54,805 8,440-pound Ford was just $65 and 220 pounds more than the $54,740 8,220-pound Silverado. Both lacked fancy equipment such as leather seats, navigation systems and sunroofs.

The location and the load

We knew we needed a real-world place to test both trucks, so we chose the eastbound ascent from Dillon, Colo., to the top of Eisenhower Pass on Interstate 70. It’s perhaps the toughest stretch of road a loaded truck will encounter on a major cross-country highway – call it the Nürburgring of pickup trucks because nearly every bit of towing and braking hardware is stressed to its max for multiple miles at a very high altitude.

The grade starts at about 5 percent for two miles and increases to about 7 percent for the remaining six miles, to the entrance to the Eisenhower Tunnel, the highest vehicular tunnel in the U.S. Despite that lofty elevation, an average of more than 30,000 vehicles crossed in both directions each day last year, according to the Colorado Department of Transportation.

We also needed a heavy trailer that the trucks could share. Chevy lined up a 6,500-pound gooseneck with three 4,140-pound pallets of flagstone lashed to the flat bed for a grand total of 18,920 pounds. That brought the gross combined weight rating for the Chevy to 27,140 pounds before four adult males jumped in and added another 800 pounds, for a grand total of 27,940 pounds, or 96 percent of the Silverado’s maximum GCWR. The total for the Ford F-350 was 28,160 pounds, or 94 percent of the Super Duty’s maximum GCWR.


For our test, we used a stretch of I-70 that started in Dillon at 8,776 feet and ended at exactly 11,000 feet, rising 2,224 feet over 7.6-miles (approximately 40,000 feet).

But we didn’t just time the trucks up the grade. We also evaluated their exhaust-brake performance while heading the opposite direction back to Dillon with the nearly 19,000-pound trailer pushing these monster HDs downhill. An exhaust brake saves on brake and transmission wear by clamping down the engine’s turbo vanes, creating back pressure to engine brake the truck. It also reduces the potential for brake fade during long descents, increasing downhill safety while towing and overall wheel brake life.

Where’s Ram?

If you were wondering where the Ram 3500 is in all of this, it wasn't included because these weights exceeded its 24,500 maximum GCWR by more than 2,500 pounds. It wouldn’t have been safe or responsible to test the truck in these conditions.

To help manage these astonishing weights, which we couldn’t have imagined a decade ago, we used a professional driver with a commercial driver’s license paid for by Diesel Power Magazine. Please see Diesel Power for the driver's bio.

Hill-climb test


Each truck was run up the grade in Tow/Haul mode starting in four-wheel drive for max traction in the cold conditions and switching to two-wheel drive at approximately 30 mph. The fastest time was used for the comparison.

We ran the Ford four times. The first two runs were with only three adult males to offset the Chevy’s 220-pound curb weight advantage, and the last two runs had all four of us in the trucks. The fourth run was Ford’s fastest time. Two-hundred-twenty pounds doesn’t matter much when you’re pushing almost 15 tons against gravity.

Temperatures ranged from 5 degrees to 18 degrees, according to the trucks’ outdoor temperature readouts. It was so cold that neither truck’s fan turned on, though the next day, at just 35 degrees, both trucks’ fans turned on frequently to cool the engines.

The trucks were at a dead stop before each run. The driver ran wide-open throttle from start to finish. We didn’t encounter any traffic on the road during the late-night climbs.

We used our own GPS-based Racelogic VBOX test kit to record performance and geographic data.

The Ford F-350's best time up the grade was 10 minutes, 46.8 seconds at an average speed of 42.41 mph. The top speed was 58.5 mph, and it happened just before the point where the grade increased from 5 percent to 7 percent.


This chart shows each truck's speed climbing the 7.6-mile grade against the clock. The Silverado reached 11,000 feet in 518.2 seconds and the Ford finished in 646.8 seconds.



This chart shows the speeds of both trucks relative to each other over the 40,000 foot (7.6 mile) run to 11,000 feet in elevation. Note how similar the speed patterns are for each truck as the grade changes throughout the climb.


Average speeds

The Chevy Silverado was significantly faster. It finished more than two minutes ahead of the F-350, in 8 minutes, 38.2 seconds. Average speed cruising up to 11,000 feet was 53.63 mph, 11.22 mph faster on average than the Ford. The Chevy’s top speed was 67.38 mph for a few seconds before the grade changed from 5 percent to 7 percent.

The Chevy and Ford had similar performances at the start of their runs. The Ford clicked off the quarter-mile in 31.25 seconds at 45.13 mph, and the Chevy ran the same distance in 28.93 seconds at 50.3 mph. But the Chevy was already coming on like a freight train at that point. It took the Silverado 28.56 seconds to go from zero to 50 mph, while it took the Ford 42.02 seconds.

Both trucks ran the first part of the grade in 4th gear and dropped down to 3rd gear for the rest of the climb.

Exhaust brake test

For the exhaust brake test, we exited Eisenhower Tunnel westbound and set both trucks’ speed to 55 mph in 4th gear. The Silverado has a push-button-activated exhaust brake that can work in or out of Tow/Haul mode, while the Ford’s exhaust brake is automatically enabled when the truck is in Tow/Haul. Unlike the Duramax, the Ford’s exhaust brake can't be turned off by the driver.


We wanted to see which truck required the least amount of wheel brake application, so when speeds reached 60 mph, the driver applied his left foot to the brake to slow down the truck to 52 mph to start the cycle again.

The difference in exhaust brake performance (echoing the much shorter test performed in the HD Shootout) was starker than the difference towing up the hill.

After four runs in the Ford, we had to manually slow the truck between 11 to 14 times during each descent to keep it from exceeding 60 mph. Ford’s exhaust brake seemed to have minimal effect slowing the rig and keeping our driver from getting that “white knuckle” feeling you don’t want to have when your 15-ton rig is rolling down a hill. Ford’s six-speed transmission did a nice job downshifting from 4th to 3rd gear after the foot brake was applied to help slow things down.

The Chevy was a superhero on the descent. It was like Superman digging his feet into the pavement to stop a runaway locomotive. In three downhill runs, we averaged one to two manual brake applies. That’s it. It consistently hung in at a steady 58 to 59 mph and stayed at that speed for miles. When we applied the foot brake after the first time, the Chevy downshifted from 4th to 2nd gear near redline at 52 mph and kept shedding speed until we tipped into the throttle to get back into 3rd and started picking up speed again. We never shifted down to 2nd gear in the Super Duty, slowing the truck to 52 mph.

At the turnaround point in Dillon to start each test cycle, the most telling aspect of our exhaust brake test was the strong smell of hard-worked brakes in the Ford and the absence of that smell in the Chevy. That doesn't just save on brake wear. It saves on frayed nerves as well.



In short, the Chevy Silverado's performance surprised everyone, given Ford's higher stated power figures for the 6.7-liter Power Stroke. Finishing two minutes ahead of the Super Duty over a 7.6-mile grade at more than 90 percent GCWR is nothing short of a dominant showing for Chevy. The exhaust brake performance is perhaps even more telling and welcome news for frequent heavy towers.

What accounts for the significant performance differences between the Chevy and the Ford in this comparison? We originally thought it might be a gap in the Power Stroke's high altitude engine calibrations, which optimize combustion performance based on driving conditions, but now we think its part of the nature of the 6.7's unique single sequential turbo.

Ford's turbo features a single turbine and two compressors placed back-to-back. It's possible that Ford's siamese compressor design is losing some efficiency the higher it climbs.

For braking, both trucks depend on variable geometry fins that surround the turbine. They clamp down to restrict exhaust flow and create back pressure in the engine to slow the truck down. The Duramax appears to be able to clamp down more strongly than the Power Stroke.

Interestingly, Honeywell subsidiary Garrett is the same turbo supplier for both diesel engines. 

Regardless of the cause of the performance gap between these two incredibly capable HD pickups, we reaffirm the results of our 2010 HD Shootout in the real world. There’s no question that GM's latest diesel pickups are the performance leaders in the class. Chevy doesn't just run deep. It runs high as well.

LOL I Hope Ford boys like the smell of burning brakes..Because you are going to get alot of it...

@HEHATEGM. Come on buddy, its taken Ford quite some time to come out with some serious gas V8's. Besides, wasnt this a DIESEL comparison.

You know, since you bring up the gas trucks, GM will be coming out with the GEN V smallblock soon. Like it or not, GMs small block V8s are ALWAYS a force to be reckoned with.

I do give my respects to the Ford gas engine design team for 2010/2011. They are (finally) on the right track. Also, that new Ecoboost looks promising.

The state-run truck won. Maybe Ford should have taken Obama's bailout money too. Can't beat the government.

Top Dog,

exactly! It took Ford almost ten years to finally put a good gas engine in the F-150 and these ford boys are acting like Ford has always dominated in this regard...

GM has always had better Gas V8's then Ford... The new Gen V small block won't be any different...

Watch how you throw the word always out there...not this year buddy!!!

I want ot see a real test i dont care about some high altitude test cause chevy knew they would when that, there should be another test like at a farm or ranch like pulling stumps out of the ground and mudding towing 35,000 pounds of cattle to the auction plow through six feet of snow going to a truck pull and pull a 55,000 pound transfer machine, come on i want to see a real test off pavment not on some road in the moutains chevy new cause of fords gearing that they could win in high alltidude but not on a real test pulling real things on smow and plowing through six feet of it!!!!!!!!!!!!!

@ tyler
Come on it doesn't get more real than this test. if the chev stomped the Ford at 19000 lb it would do the same at 35000 if your crazy enough to do that. And with Fords axle hop issues it would just be worse for Ford to test the trucks on pulling stumps and plowing snow in less available traction conditions. and the gearing was the same, its not Allison's fault tht they know how to gear a tranny that much better than Ford.

@Tyler, we should see a test to see which one floats the best, cause I live next to the beach and I want to see how far into the ocean I can drive.... lol

Now thats a real truck. lol Pulling cows or block is pulling and GM did that fast and safer than the Ford. Grow up Ford people.

@Jake, well put.

@Nick, You are correct, not this year. Thats why I gave Ford respect on their new gas V8s. I also give them props for putting a Turbo V6 in their F150 while completely spanking their own V8s! Makes a guy wonder what is up their sleeves.

I still have no doubt GMs Gen V V8s will reclaim all these titles again! But, will they have the fortitude to eclipse their V8 offerings with a V6?

Its going to get intersting with the ecoboost out there and with all of fords new motors, i hope chev ups them! better for us, just means more power for the upcoming models

Back to these high performance diesels. im amazed at what these trucks are putting out for power right now. Im cuerious so see what D-max is going to do here within the next couple years. (been hearing they are at the max for its power ratings).


Congrats on two very tough trucks, Gm you guys have shown that your company was deserving of the bail out and that your trucks are strong and class leading.

I am a Die hard Dodge guy, Ram Mopar whatever they wanna call the brand lol

I will say that i cant wait until the new cummins and 8spd transmission comes out. I know that Dodges tend to claim lower numbers than what they are really capable of, and this is a fact. in this case the Chevy proved that numbers are just numbers.
Lets hope that my truck company will also come out with a tougher powertrain, because the Ram's interior are already a major step up.

The next time I'm hauling 20,000 lbs through Colorado I'll think about this "test". Most people that buy these trucks will NEVER even come close to working a truck in this way.

Most people want a truck that delivers performance that is acceptable to them and is comfortable while driving and hasn't looked the same inside and out for the last 10 years. While yest GM is the winner in this ridiculous test, it would be really funny to hear how the two trucks compared inside and out. Other than the smell of overworked brakes and getting up a 40,000 fl long climb a little slower how did Ford fail?

The interior qualify of the GM trucks is horrible. It's 10 years behind Ford. OnStar? Really? Who cares? Take a look at all the Ford has to offer in the way of electronics and creature comforts (the things that really matter) and you'll never look at GM again. ;)

The ROCK has proven it's capabilities once again,, any questions

I wonder how the trailer sway control sytems stack up?

@jake you all were sore losers and crying about how the last showdown was unfair!! by the last Showdown i mean the v6 work truck, its always PUTC's fault F that. Chevy won good job im a ford guy and I still think ford makes the best HD and LD trucks PERIOD! But mike levine and the PUTC team put out phenominal articles! Whether ford dominates wins by a little or loses idc great job and forget these sore losers and winners.


I still say it is hard to believe the GM did that much better in this test than the Ford considering these were "supposedly" the most evenly matched trucks in PUTC's history.

It is too easy to manipulate a diesel engine via electronics. Look what EDGE programmers do. That's why I would want each truck independently certified BONE STOCK.

In the half ton tests the Ford got stomped, yet I have yet to be bested by my new truck buying buddies.

In regards to safety, Fords trailer sway control is FAR better and is the real safety of a truck. Burnt brakes are the result of someone who doesn't know how to drive in the mountains, and for the purpose of this test, they were testing the engine braking, a new technology, and GM's was definately better...Not safer.

It looks like someone was on the take...... There is no way Chevrolet could have beaten Ford. The power figures don't lie. The people who ran the test lied. Plain and simple!

This just proves that the Super Duty simply can't do what Ford says it can. Ratings don't mean anything. And this just proved it.

Good tests guys.

@Rick: You're calling me a liar.

If you think I'm going to throw away 15 hard-earned years bootstrapping myself and earning my credibility the hard way in the auto industry over this test, then you should start reading about trucks elsewhere.

You're not wanted here.

Thank You!

At least Chevy got 1 sale out of this test.

6.4 H&S tuned powerstroke with a intake, good luck trying to keep up duramax and cummins!!!!HaHa;)

Mike, I would hope that Rick was being sarcastic towards all the whiners. Either that or just a troll.


Mike L just showed a weakness. He's suppose to be deleting it, I think we are seeing his true side.

Time will tell, I better watch what I say or else he will tell me "I'm not wanted."

I wouldn't say that though if I were the Moderator of this site, I would just ignore the comment.

Some people are stronger than others.

@Frank: You can pretty much call me what you want to. I've got a thick skin. But don't call me a liar unless you've got proof in your hands.

I do not know which is worse - a sore loser or a gloating winner.

Ford guy here! Great article Mike. I too figured that the Chevy would win, but I wondered why it would before the article and I am still left wondering now exactly why??? There is a reason that GM proposed this specific test and Ford denied it. The results are now in. Is the difference really the altitude and the turbos? I'd really just be interested to know. Fuel mileage numbers would have been a very interesting tid bit to add here too. I bet you guys burnt those poor fuel cards up on both trucks though. For the record, my '08 6.4L King Ranch is still safe until I can(if ever) afford a new 6.7L.


Nobody was drag racing up a mountain...any truck can do that (but the GMs were better)

Where GM really murdered Ford (yet again) was the down hill descent and the engine brake. When you're spending 60K on a shouldn't get the white knuckle feeling like the driver did in the Ford.

Again, this test confirms what we already know...if you want a flashy truck where you can talk to your radio and blind people by the size of your grille, then buy the Ford. But if you need to do actual buy the GM.

While yes it is great the GM has good exhaust braking capability, I still question why you need to be going in excess of 70 mph down a 7% grade with that much weight behind a pickup truck. I think they need to DERATE the pickups nowadays in power; Some people who are hauling large loads (fifth wheels toyhaulers blah blah) are the same idiots who modify their trucks to go 85 mph up hills and 'try' to go 80 mph downhill because it is a 'safe' section of road.

@Top Dog what's it matter how long it took Ford, they are doing it.

Since we are talking the past, this is so much like the last gen Mustangs vs Camaros. The Camaro ran away in power but Mustang outsold Camaro so bad they had to stop making them.

Like I said, only important thing is if it sells. How long has it been since GM outsold Ford trucks? Not to mention Ford just announced they have 50% of this market, gaining 80%.

Like I said, keep up the chest beating. Winning the battle, losing the war.

@Mike Levine,

I agree. I respect you, your site and try too with others. I'm guilty as much as others are. However, it takes a TRUE MAN to admit that.

Thanks for all the reviews!!! I think we can all agree that your work here is stellar. Thanks again!

@TX_Ranger. GM has the option for a detuned duramax in the 3500 class. I wont tow this much weight, but it wont be because the truck can't do it.

I think Diesel technology is awesome. Even though it has a higher premium, I feel its worth every penny....even if the truck never sees a bag of groceries!

Actually "P" The Chevy truck has about the same amount of chrome as the Ford on the front end, its just all on the gigantic front bumper lol.

1st and foremost great read. I am a ford guy and as such would still buy a ford, but GM has a great powertrain. 2nd-Frank you might be joking, but in my professional world calling someone a liar can get you seriously injured (I am a correctional officer or prison guard if you must), so I do understand were Mike Levine is coming from. Big business sue for millions, just because people make claims without proof. It is self-preservation if nothing else. Did Rick make a claim without proof? Yes Mike just defended his position as a journalistic professional. Now back to the test wish I could have been there.

@HeHateGM. I believe I gave the Ford team props. Its all good that Ford sells better (for now).

I don't hate Ford. But time and time again, Ford wraps an overall great vehicle around a lackluster, overrated engine.

GM has done this to. But in this case, GM has the better vehicle as far as its powertrain is concerned. And its cheaper too! The interior, exterior and SFA vs IFA arguments are based on personal preference and opinions.

This test, however, is based in fact.


Gotcha! I didn't know it was such a big deal. I'm not calling out liars here, but dang it's sounds childish.

@Frank- Hey we are on the same side, I was just trying to explain Mike's position. And I will point out to all EVEN FRANK here was one of the first to give props to GM for their win!

Wow I guess the gm boys don't like me talking about suspension. I wasn't really focusing so much on the article with my suspension comment as I was the attitudes that have surfaced because of this test. This test proves some aspects about gm having an advantage. It seems to me most peoples comments focus on gm being the best truck in every situation. For instance with my ranch comment I was referring to an aspect that gm would not be superior in. Really this test doesn't sway my loyalty or many peoples. My good friend with his stock 1992 propane 460 superduty pulls 12,500 kilograms around daily on his tri axle gooseneck up here in B.C. Canada. That's why Ford has my loyalty. Regardless if G.M. Has the fastest diesel. Congrats G.M.

Great article mike.

Since the test was at night, how much better was the Chevrolet's headlights than the Ford's?

Any thought on reversing? The Allison transmission reverse is MUCH shorter than the Ford's (over 40% greater)

Ford F-Series has been the best selling truck brand for 33 years now and I really don't think it will change anytime soon. Chevy did do well here, but the only thing this test shows is GM/Dodge finally had to do some hard work and spend a ton of tax payer money to match or beat the dominant force in the truck market which is and always will be the Ford F-Series.

U.S. Truck Sales as of October 2010:

Name Plate Units Sold
1. Ford F-Series 385,879
2. Chevy Silverado 267,715
3. Dodge Ram 140,889
4. GMC Sierra 90,235

Ford and Chevy do hold the top 2 spots in U.S. vehicle sales with Toyota Camry in a close third and the Dodge Ram is way down in 13th spot. All those problems with the Camry caused it to lose the 2nd spot over last year. Just think, a few years ago Ford was selling over 1,000,000 trucks a year and Chevy just a few 100,000 behind and now it's just over a 1/4 of that.

From a Ford guy. Congrats to the Chevrolet truck.

To the GM fan boys. If I remember correctly, didn't the Camaro out perform the Mustang for years, and yet, people still preferred the Mustang over the Camaro? Now if I remember correctly just as the Camaro was outsold by the Mustang, the Chevrolet HD is outsold by the Ford SD. That shows that no matter what, performance doesn't mean squat when it comes to selling vehicles. Rarely will someone ask what the 0-60 is on a vehicle that will be a workhorse. In my time as a car salesman, I only quoted 0-60 on the Mustang. Nothing else. Not even the F-150 Lightning or Harley Davidson F-150's.

Sure the Ford may not be the fastest, but it still get's the job done no matter what.

So what if GM got a few seconds faster? that doesnt make it a better truck. It just meant that it got there faster, not by a big margin but seconds. That is not even enough time to even count. I guess GM has to try to beat ford somehow, I guess GM is really happy about a couple of seconds? Its not really impressive if you look at it, but I guess for you GM fans its impressive. For a truck driver like me that pull loads over these mountains GM really didnt out do ford by any margin at all. just a few feet or secounds? ( not impressive)

Great Job Chevy!! Looks like you won this shoot out. This is good for everyone. Those who drink Chevy Koolaid will brag and those who drink Ford Koolaid will find an excuse. BUT, in the end this is a win all for everyone. Competition is GREAT. It makes a better product for all of us.

Personally, I wouldn't drive a GM product.... any GM product. I refuse to pay twice for them. Additionally, I am not happy with GMs lies about paying back their loans. They are WELL over 100 billion in debt (Ford being just over 20 ) and will NEVER pay it all back. I chose an F150 over a Silverado 1500 because of the 3 star side impact crash test rating of the 2010 Silverado 1/2 ton. Nice job Chevy. You are fast and "smooth" but don't get hit by anything.

Once, Again. GREAT JOB CHEVY!!! I just sit back and wait for Fords response with new and innovative products.

Mike B, It was actually a couple minutes faster over several miles, not seconds. But I hear what you're saying. I will buy the best overall truck, not simply the fastest at high altitude.

Nice trucks. It amazes me just a decade or two ago, 420lb of torque was a lot, now you have 765+ torque from both trucks and their towing/hauling abilities are creeping up to medium duty specs. Back in the 90's the Powerstroke was the King, but I'll admit, ever since GM introduced the Duramax/Allison combo, the tables have turned.

BTW, great article Mike.

great test. and yes ford continues to sell more trucks. so, is china a better country because more people live there? just because folks are loyal doesnt always mean better. more people buy hamburgers from mcdonalds than burger king...are they better? public opinion often hides facts, 2 trucks pulling up a hill exposes them. i've owned 3 duramax powered trucks, no ford around me could run with them...maybe i was lucky i guess.

GM obviously put the taxpayers money to good use, they still won't get a dime of my money and the results were too close to say it dominated the Ford.

It would have been a shame if GM would have performed poorly, they bilked taxpayers fro billions to get an edge on Ford.

Congrats GM. As a proud owner of a 06 LBZ DMAX, all I can say is wow. What a fine job GM and Ford have done in the Horsepower (Torque) Wars. It keeps both on thier toes and striving to improve already awesome pickups. If I have to buy a new pick up it will definitely be a duramax again. Ford lost my business when my father's 03 6.0PSD to a crap. He too has an LBZ. Anyways if someone hands me the keys to either of the three I will gladly accept ownership.

great job to gm. but its like alot of people said. even though gm wiped the floor with ford, i would still take the ford anyday over the gm. dunno why (could be the fact that i wouldnt work the truck this hard), but just would. cool test forsure
