I pulled the trigger on a 2016 Sierra 2500 HD CC. I traded my 2014 Chevy Silverado CC. Main reason we're the miles I was accumulated during the first 2 years.. Sitting on 81,000 miles the a/c went out, trans slipping, electronic locks stopped working... Ugh long story that's just a few issues! Anyway... After buying my new truck, I did alittle digging on the 6.0 motor vs the 5.3.. Me not being a motor head or much about engines at all believed that the 6.0 would have major increases in torque & HP compared to the 5.3... I was wrong and left in shock..

 

This is what I found on the 6.0:

HP- 360 @ 5400

Torque- 380 @ 4200

 

5.3-

HP-355 / 250 @ 5600 (gas SAE certified)

Torque-383 / 519 @ 4100 (gas SAE certified)

 

I do understand you gain the ability to haul more weight with the 2500, but don't you think they would give the 6.0 more advantages HP/Torque wise to bear the pain when spending 3-6g more on price!? Just my .2$

 

Coming from a 5.3 w/ 308 rear end, I'm much happier to say the least.... It wasn't hard to get me out of that truck and make me happy:)! Love my new truck

The 6.0 is a workhorse, not very powerful for its size but they are bulletproof. The 5.3 is more for the light duty pickups that the average homeowner will tow or haul something seldomly

Congrats on the new truck!!!

 

There was more of a difference between the two motors power wise until the new gen 5.3 came out in the '14 model. The 6.0 has not been updated, YET. I say it that way due to many, many people wanting and dreaming about the next gen HD gas motor. They can't wait!!! Lol Hoping for more power, between fuel mileage, etc. the 6.0 is an awesome motor that still competes with the other two (6.4 & 6.2).

 

Other difference is the 6.0 is still an iron block while the 5.3 has been an Al block for some time.

Congrats on the new truck!!!

The best part of the 6.0 over the 5.3 is the great rumble coming from exhaust!!

 

Congrats on the new ride.

That is true! I had a flow master 10 series on my 5.3.. How are these trucks with just a muffler delete? Heard good things & it doesn't cost much at all!

The 4.10 rear end makes a huge difference over the 1/2 ton 5.3 drivetrain.

Yeah, the 4.10 is a major deal, and take a close look at torque curves for both engines. The 6.0L L96 hits 90% of available torque at 2000 RPM, the curve from then on is mild on up to the top. Much better than the 5.3 torque curve. A better working RPM band that meets work truck needs. And, of course, no AFM. How it delivers power is equally as important as the power rating. Great intake and exhaust setup straight from the factory to maximize the band of the engine. Only a need to drop the trash can muffler and put a nicer sounding straight thru. I put a Magnaflo on mine.

 

I fully appreciate the GM hasn't walked away from this setup. 3/4 of the 2500/3500 market is commercial, and this setup is one that a lot of commercial users like. Reliable, capable, long lasting, etc. GM has to really watch it how they change things. if they goof up, they will lose a large commercial segment and take years to recover. I like things just the way they are.

I agree.. The numbers are close and fool the average consumer such as myself until driven.. It's a night and day difference. The 4.10 rear end is phoenomal! I haven't seen the curve charts for the torque etc.. that's my fault for not doing that research...

 

I forgot to mention the AFM!!! Good god... I'm so happy it's gone. that was the biggest dread of mine on my old Silverado. There is no lag compared to this beast.

 

You mentioned dropping the garbage can muffler.. Yes it's huge!!! I've been known for always changing my exhaust.. My 2014 had a 10 series by FM. Loved it. Until v4.... Awful. Wanted to shoot myself! I'm excited to drop this huge can of metal they call a muffler and throw something new on... I've read a few different opinions.. Has anyone dropped the muffler and simply threw a fill in piece ? How's the sound, any noticeable performance change? How is the magnaflow muffler on this truck, what model did u choose?

Congrads on the new 2500, there the workhorse truck not the racehorse truck. I wouldnt get to worried about the numbers just the physical size over your old 1500 will make it a comfortable puller. Mine has a nice 2800 payload which means I can carry everything I want period and still hookup and pull my trailer. Lets see some pictures of that new ride

Forgive me but I didn't understand the 355 / 250. Or the 383 / 519. ?? Why are there 2 numbers for torque and HP?

 

The first number is lb/ft. The second number is Nm.

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      By Tyler Gibbs · Posted

      The curb weight on a 1 ton crew cab long bed is around 7k lbs.  Now, I don't know where you went to school but 9k is not more than 2x 7k lbs. More than 2x 7k lbs would be 14k+.   With that said, obviously yes you're going to feel a 9k lb trailer when slowing down.  I already said, when accelerating.  When changing lanes?  No.  But if you look at the context of what was quoted, the original person said, "after a mile or two..." which means that would be after the accelerating portion and you're driving a generally steady pace.  Please do learn to read and comprehend.

      Like I've said before. Di and Carbon buildup is not that big of a concern. Engine had minimal buildup, and that engine was obviously not super well maintained. Do regular oil changes, and you're gtg as long as the rest of the truck lasts. Also, the High Pressure FP that people ****** about, but can't tell you why.  Now, I wish they'd trash the variable oil pump. No real world issues with them, but I'll gladly eat whatever miniscule MPG it's saving me in favor of more oil at all RPMs.    Curious to see his assessment of the 7.3 compared to the 6.6. I expect he'll praise the port inj, but from a structural standpoint, the 6.6 is as robust as any engine out there.    Not to take away from the 7.3. I feel it's equally as good as the 6.6.     As to heat on the rear cyls, I'd have to see numerous examples before I'd say it's an issue. Especially not knowing the history of that engine. For all is known, they could have blown a rad hose, and ran it hot, and the 2 rear cyls may be the first to get hot in a low coolant situation, but not be an issue aside from that.

      "Life is getting back to normal."    I'm driving again and all new joints are operating as expected for this stage of recovery.   My most recent joint replacement still requires a lot of attention but experience has taught me that time will quiet the remaining pain.  I joked with my surgeon that another joint replacement would take my mind off my most recent surgery and he responded by saying the next will be a hip!  There are no plans for another surgery but, unlike me, I don't think he was joking!  I certainly wouldn't refuse further replacement  if required but hope to spend time out of the "post-op"  period.  I can't stress enough that if you have been recommended for total hip, knee or shoulder replacement that you welcome the offer.  Post-op "recovery" may sound daunting and painful, however, this is far better than the insidious erosion of mobility you are currently experiencing.  Imagine what it would feel like to wake up most mornings feeling better and more mobile than you did the previous day!  Prior to my first surgery in June 2025, even getting out of bed was becoming a formidable task.  Since the day after my first surgery, I get out of bed everyday easily and unassisted.  Making the switch to feeling a little better each day rather than a little worse, is hugely motivating!
