What have you done to your K2 today?

6.2L is a superior engine to the 5.3L. I've owned both including the L92 and L86. The additional horse power and torque make a whole world of difference. The downside though is that the gas mileage will suffer compared to the smaller engines like the 5.3L.

From what I asked around and from what I read it wasn't worth the additional weight and gas consumption. Too big of an engine for the 1500. And no point getting it in the 2500 because the diesel is offered

Too big and too heavy? I'm not really following that logic at all. The increase in performance from the 6.2L is a night and day differnece compared to the 5.3L. Yes it may not be the most economical choice but at the end of a day its a truck. It's nice to have the additonal power when you have truck loaded up with people, gear and toys. Not mention if you tow why would you not want the additonal horsepower, torque and larger rear end?

I'd have to agree wholeheartedly. I had a 2008 Silverado 5.3, a 2012 Silverado 6.2, a 2015 Sierra 5.3, and now a 2015 Sierra 6.2, so basically 1 of each engine on both old and new engines. The 6.2 is worlds better on both the old and new platform.

I just assumed bigger engine more needed so it's heavier. Biggest engine less romantic under the hood. More heat harder to dissipate

Damn auto correct. Room under the hood.....

I have the 5.3 with 3.42 rear end I have no trouble towing my 6klb boat or my buddies car on a car hauler can't be more than 5-6k milage is not great but it's a gas I only tow occasionally. Anytime you want to tow enough you need the 6.2 why not opt for the diesel and get good fuel millage and ability to tow 20k lbs

The physical size of both engines is exactly the same at 25.2" wide x 32.2" tall. What creates the larger displacement size is the bore. The bore of the L83 is 96.01mm where as the L86 is 103.25mm. Also, between the 5.3L crew cab/short box with max tow and 6.2L crew cab/short box with max tow the weight difference is 185lbs. For comparison the same configurations but with the standard bed (6'6") the weight difference is only 174lbs. I choose this configuration because both trucks will have the exact same drivetrain including the larger rear-end and 3.73 gears. In reality I have absolutely no clue what the difference in weight is between just the two engines but between the two trucks it's a very small difference of about 3%. Check out the two links below about each engine, it shows the materials used in the engine, horsepower & torque ratings, engine rpms and so on.

The links don't work. I am curious for more statistical information

You need to have adobe acrobat installed. For example if you use Google Chrome there is an adobe acrobat extension that will open the file in a new tab for quick viewing. Then you can save the files and/or print them. If that doesn't work just google search "L83 gmpowertrain" and "L86 gmpowertrain". And you will come across the links that link to a pdf on the first page of the google search. The L86 has more forged internals too which is nice.

Had my Bilstein 5100's installed on the front of my truck this morning. Went with the highest setting and the ride is still way more improved over stock. Stock shocks felt like there was some jarring over sharp bumps. The Bilsteins really smoothed that feeling out.

Awesome! What color? Should be a great looking truck.

The LTZ was blue, but the HC is black.

I found it i appreciate it
