that 6.2 has massive jugs, have a hard time thinking that’s same block as the 5.3

 

This confirms it.  You don't know.  That's not an admonishment..... you are smart, enthusiastic and like to spread knowledge.  So I'll help you with a few points. 

 

You are definitely on point that the 2.7L is a lighter power plant than either the 5.3L or 6.2L.  You are wrong about the physical size.  Generally speaking GM has been making one size (external dimensions) engine block per each generation of V8 they produce.  The exception is back in the day when there were distinctions between "big block" and "small block" engines.  The last "big block" engine in a production vehicle was in 2010.  In absence of that big block differentiation..... all GM V8's use the generational block design..... and the external dimensions don't change meaningfully....its the internal castings of the blocks that might be different or even materials between the blocks. 

 

For the current generation 5.3L and 6.2L they are both aluminum block Gen V V8's.  External physical dimensions are the same.  Weight differences negligible..The 5.3L should have more block material because of smaller cylinders but the 6.2L should have a slightly heavier crank because of the slightly longer stroke.  But at the end of the day it would be negligible and not noticeable. 

 

Other things you have to consider weight comparisons are the transmissions and definitely the trim levels.  A Custom Silverado vs a AT4 is going to have weight differences that will be attributable to extra features.  Plus the AT4 likely had a 10 spd.... no idea if the custom did.  The 10 speed is definitely heavier.  but based on what you said I dont think you can logically draw 500lbs difference due to the engine being pig heavy. 

 

I'd venture to guess most of your observations are seat of the pants feel that is probably very much bias fed....... and that's ok.  You are really happy with your truck and you should be.  But let's spout facts.

The weight of a 6.2 is actually about 80 lbs lighter than a cast iron block 5.3.

All 6.2s are aluminum block.

5.3s can be aluminum block also but most are cast iron.

I also didn't buy the 6.2 to save gas. 

 

 

...you do realize the 5.3 has been all aluminum since 2014...right?  Block and heads.  L84 vs L87 the weight isn't all that far apart for the current engines 5.3 and 6.2.  

 

2013 was the last year for an iron block/aluminum head 5.3 which were gen 4 LS.  They offered both iron block/aluminum head and all aluminum in gen 4 LS and I believe late gen 3 LS.

I did not say the 535 lb difference was all motor. Learn to read better. I said I don’t know much of that difference was motor. Yes 10 spd vs 8,  yes at4 stuff, spray liner, 10” longer box, leather sunroof side steps. We know at minimum 160 lb was motor lol but the gmc 6.2 felt like a tank compared to lighter nimbler custom. 
 

Now that we cleared that up. Pump your air with 8 cylinders or 4 and 1 turbo. The only possible advantage I could come up with for the 8 was subjective....sound. A useless measure. And in fact for truck duty for long highway and outdoorsman stuff the stealth of the turbo motor has proven a bigger winner also. 
 

enjoy your lifters and weight and loss of power at elevation and fuel economy etc

Base curb weights straight from GM for a Crew Cab Short Box 4x4, lifted;

 

w/L3B 2.7L - 5010lbs

w/L84 5.3L - 5080lbs

w/L87 6.2L - 5240lbs

 

ZR2 w/L87 6.2L - 5550lbs

ZR2 w/LZ0 3.0L - 5710lbs

 

Looks like a 70lb difference between the 2.7L and 5.3L, the extra weight of the 6.2L truck is from additional standard features like bucket seats, heavier axle, etc.

While I agree the 4 cylinder is one bad motor. From my first V-8 Ford truck a 289 to my Avalanche the V8 sound is a symphony to me. Driving my 50K miles a year the rumble of those twice pipes made the trip. My biggest enjoyment of driving my avalanche besides it’s a truck. Hearing the V-8 rumble at startup and cruising. I appreciate the other engines, I got to have that sound.

Have you made up your mind about which truck to buy?

LTZ way better value, everytime i see a TB I think the dude just doesnt know any better....your paying a premium for something you can do better....

 

AT4 is a different story....

OR it could be that the TB owner found a truck that looked like he wanted and doesn't have the time nor the care to do all the work himself.🤷‍♂️

Nope, still waiting because it seems like prices are coming down in Canada. I still want the Trail Boss, but the withholding of options still annoys me.

 

Another gripe is why do the RST and TB, the sporty and rugged off road trims, have fake wood trim on the interior? I could not think of a worse choice, it should be black or something with a metal look/pattern to it. Of course in the AT4 and ZR2 there is proper carbon fiber pattern trim. I guess it's a classic strategy, you're still getting hosed price wise on the lower trims, and to step up trims and get proper options, you're really bending over.

Honestly, buy a Z71 or X31 package truck with the options you want and for about $500 parts and less than $500 labor if you can't do it yourself you will have a better truck than a Trailboss/AT4.  Tires will be extra but still less than the TB/AT4 premium and you'd have to choose pretty poorly to not get a better tire than the Goodyear crap.

I based it off the fact you were using that one experience and the weight difference to base your judgements on and you cited 500lbs.  Sure you said you didn't know how much that was attributed to the motor BUT you attributed your entire opinion of it feeling like a heavy pig because of the motor. 

 

Egghaus got it right.  There is roughly 70lb difference between the V8 and the 4 Banger fully dressed.  6.2L trucks have a heavier transmission, and more standard equipment.  Those are not meaningful weight differences. 

 

You are happy with your 4 Banger....... and no one is saying you shouldn't be.  Is it really necessary for you to justify your liking of it by spouting off statements not based in reality but just based on your own self admitted uninformed opinion on the other solid options? 

 

I guess you got us with the lifters.  You win?  Is that what you are looking for when no one is saying there is anything wrong with your choice....but also noting that there really aren't the problems you think with the others.  But if validation is what you are looking for..... I guess you can take the W with the lifters.  Or the W with NA ICE losing power at elevation. Hopefully you got the validation you are looking for and don't feel the need to justify your enjoyment of your truck by trying to take down others!

Yeah classic differentiate trim strategy...... the good news is that you can get some overlays that look nice and cost way less than the upgrade to the upper trim levels.  I just did that in mine last month and am pretty happy with the aesthetics.

the engineers in video said 5.3 is 160 lbs heavier, also, two headers, two cats, dual exhaust? the 4 banger has one of everything, it would be hard pressed to outweigh a typical modern aluminum 3.5 v6, yup...no lifters, one head, one string of valves, lighter trans, it's less of everything to support it and you feel it on the nose and in handling overall and my assessment of the 6.2 handling as a wallowing fat pig compared is still accurate, I spent time in both, 3 weeks with the pork chop knowing I was getting the turbo, I paid extra attention to log the differences, anyone else here do the same?, I'll take that W for no lifters, and another for boost and having no power losses due to elevation, another W for having peak torque 1100 rpm less...and another for having way more peak torque lol...can you solve for the lifter stuff on the 5.3? sounds like it...still a good motor, I've got a gazelle that can pull stumps lol and one of only 2 engines the gm engineers admitted to not being able to kill in trying to kill them in testing...

“Goodyear crap.”  Coming from someone who drives cheapass Coopers. AND Goodyear owns Cooper. You can’t make this **** up. . . 🤣

Goodyears have a lot of history over the past several decades of “meh” performance and worse. 
 

Yes, I’m aware Goodyear bought Cooper 2 years ago. Still not happy about it.

 

Priced Cooper tires lately?  You sound like a brand snob. Interesting choice to pick Goodyear to defend though.

    • not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...
    • First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.  
    • I always drive in Sport mode. With more driving, I am finding the initial response when accelerating is much quicker now🖕 Lou
    • Is it an optical illusion in the pic or is the truck really squatting that much horribly?
    • My initial introduction was here.  It's hard to believe that I last posted in February 2013, having just deployed to Kyrgyzstan.  Since then, I've retired from the military and the 2006 Sierra SLT Z71 that first brought me to these pages was lost.  I went forward to Afghanistan in March 2013 and did a lot of sitting behind a computer on brigade staff.  Within 18 months of getting back to the States, I was selected for Drill Sergeant duty, after which I moved back to Virginia (my home state and where I served from 2004-2008).  That '06 Sierra did a lot of driving between Louisiana, Georgia, and Virginia, and ended up with nearly 320k miles by 2022.  By then, the registration had been expired for a couple of years, but the pandemic had all but eliminated tickets for such transgressions.  Admittedly too, I usually drove my wife's SUV or son's car the 2-3 times a week I had to report to work.  Teleworking sure was fun while it lasted.   I started my retirement leave four years ago and stored the Sierra at my sister's house.  A big mess was made when her fiancé passed while she was taking care of business out-of-state in late-2024, and his son pretty much mismanaged everything to do with the estate.  Even so, I was assured that my truck was safe... until it wasn't.  I found out that my truck had been scrapped about four months after the son took over everything.  There's nothing I could do; I'm 1000 miles away and it was technically abandoned property since he'd even trespassed my sister from her own house (she had no claim to it as she wasn't married, and the fiancé was the sole owner).     Anyway, today I got my second Sierra.  This is a 2010 SLE 2WB CCSB with a little over 200k miles on it.  It's got the 5.3L I'm familiar with and should handle what I need it for.  Hauling stuff that won't fit in the Transit Connect (yep, I sold out, but that's the wife's vehicle) and towing a few times a year tops.  The price seemed decent, considering how much people sell their trucks for in the Deep South: $4500.  I've seen similar trucks listed for more than double that.  I got it from a coworker who left his tag on until we transfer the title next week (Louisiana requires a notary for transfers), so I've been driving it all day.  The rear speakers don't work, which is one of the things that brought me back to these forums earlier.  I can't say how active I'll be as a poster, but I'll be scouring the archives while I find out every little thing I can about the 2010s and particular nuances/problems with my truck.   It's definitely not a GMC, but I got another Willys Jeep a few months back as well, so I'm almost at the same place I was when I first joined gm-trucks.com.  My old 1960 DJ3A was sold back around 2010 or 2011; my current Jeep is a 1946 CJ2A.  So, I've got a slightly newer GMC and a much older Jeep.  I kind of wish I still had that F-250 I had way back when too.  The Dakota is long gone and was technically my brother's truck, though I had it registered and insured.  The F-250 had to go when my grandmother's house was foreclosed on due to mismanagement around 2012 or so.     Hopefully anyone that made it this far isn't too annoyed.  I tend to be long-winded, but I'll be doing more reading than posting in the coming months.
