My friend you are into it a lot more then me. If I had intentions on supercharging or race applications I would opt for the 6.2 because of the potential. The dash cluster in the High Country is all the same doesn't matter the engine. There are different options that would change your cluster a bit but these trucks were nearly optioned the same.

 

I'm not sure I would ever supercharge again. I had SLP super charge my SS Camaro and yes it was a blast. It grew rather old though and I never really raced it so I kind of got buyers remorse. You'll never get your money back for those things either. My kit...installed was about $7k.

 

Good luck with the forced induction. Take some photos of it.

My kit is only costing me 2500 bucks installed!

Granted I certainly don't need a kit but ebrock was looking for donor test vehicles for a discounted price I really couldn't say no!

What I meant about the cluster video is watching someone make a video of the cluster from a stop to 100 mph. Between the 2 engines I can visually see the acceleration difference on the speedo and tach verses time a 5.3 to a 6.2 so I'm surprised that you couldn't feel it

I feel the same way when I drive my 92 Chevy, 383, Dart heads , Msd, long tubes, oh yes, Whipple, 10lbs boost. I just couldn't justify 15k for the package to get the 6.2. Not when it's a net 40Hp on E 85. Not really knocking it but that's a lot of mods. I can do a gear add gear venders and a tune. And if I really wanted to get nasty, 100 shot of gas.

Yeah I'm not sure I'll go over 75 or 80 in the truck. I almost want to drive both trucks again because you're adamant about this huge difference. I honestly think I'm just numb to the difference because I'm used to driving a fast car.

 

Monday I will pick up my High Country with the 5.3l I don't see any truck drag racing or light to light racing in my crystal ball. If I wanted all that...I'd buy a lightning again.

funny you mention that because the 6.2 has more power than the lightning did in both tq and hp! lol

It does but remember the lightning was a light truck and 2wd. Couple cheap mods and lightnings were easily pushing big numbers. Whole lot cheaper then buying a brand new 4x4 and expecting the same race application.

 

Matter of fact the equivalent of your competition would be the Ford Tremor. I'm curious how that would be stock vs stock against a 6.2.

Many state about using e85 on the 5.3 to up the horsepower (which is not displacement horsepower so is not the same RPM power range effect etc...). And really who wants to use that crap anyways :dunno: if you're serious about true horsepower/Torque?

 

I use 91 (100% gas). Also, please stop saying the 6.2L is 2K more expensive. You do NOT pay MSRP on a vehicle, thus do not pay MSRP of $2K for the 6.2L upgrade. its around $1700 and is what I paid. There is no replacement for displacement and they (GM) did an amazing job on the corvette motor for a truck.

 

DO NOT GET THE 6.2L IF:

You need the extra 1 MPG in fuel efficiency

Don't mind wishing you had a lot more oomph

Don't mind not having the corvette engine in your truck

Don't mind when towing you realize what the 6.2L really gives ya

Don't mind settling for "average" :)

Don't mind sticking $1700 into the 5.3L only failing to achieve the displacement HP/TQ output of the 6.2L and dealing with warranty headaches that may arise later

 

DO GET THE 5.3L IF:

You have to....

 

These are only my opinions and hope you enjoyed.

You really should do your homework, it's 380HP, not pony or dogs. It's use to take big cubes to make big HP not so any more. I had a few 454s , 396, 460 etc. I'll take an 5.3 or even a 4.3 any day, less weight per H.P

Discounts and rebates save you money to justify a $1999 upgrade but it's still a $1999 option. Not to mention another $200 just for tax on that option and another $40-$50 a month.

 

I'm also not biased on trucks or cars of different brands. I've had my fair share so I just had to put that out there before I say this: Stop saying there is no replacement for displacement. Ford has been doing it for years. The new 6.2l barely beats the ecoboost 3.5! So obviously there's options out there.

 

My point is a stock ride by ride comparison of the 5.3 and 6.2 is nearly neglectable. Check out chevy's website and compare towing capabilities...not impressive increase with the 6.2 over the 5.3. Chevy could have done better or just got rid of the 5.3 and not charged for the 6.2. It's just a money adder.

 

On top of all this. Not trying to dog anyone....you want fast then get a sports car lol. It's a truck for crying out loud...and a truck designed for work and comfort not racing. It will never be a vette or beat a vette. Add all the power options you want to a 5400lb truck and burn 9mpg or less lol.

 

Settle for a 5.3....I think not. I made a good educated choice that will also save at the pump.

It's funny when the mpg debate comes up over and over. 1 mpg difference on the same 26 gallons nets you 26 miles more range and about 3.50 savings at the pump!

 

The towing capacity is different for each truck based on its curb weight not it's hp rating!

 

The 6.2 will without question tow easier up a hill than a 5.3 any day!

 

The reason I got a 6.2 is because they are the biggest and best engine, and the fact it's rare I felt if would hold it's resale value better.

I am the last person that needs a 6.2 as I don't even own a trailer!

And now I'm getting a blower to boot! I probably need therapy but that's a totally different subject. And before anyone asks mine hangs quite well thank you!

 

But coming from a z06 corvette I think I got a little spoiled. Also I got the all terrain for the look, have no intention of taking it off road. In fact I installed a rear sway bar to help with road manners as well.

This is all in good fun and I like that we are all learning from each other. I get your point on the curb weight. Ill still argue the mpg. Someone posted 19 or 20mpg with their 6.2. I've also heard of people getting 25mpg with the 5.3. So that's 5mpg difference. Your super charging yours. I dropped almost 2mpg in my Camaro after the forced induction so that might take a truck down even more.

 

I don't even think I'm relevant to this topic anymore. My salesmen called and he can't get the 5.3 in the specialty white. So looks like I might end up with the 6.2 now because there are actually more of them in NJ. I'll keep you guys updated but now I hate you all for turning me into a flip flopper. I still stick by my original statements, I just really want a decked out high country and now I'm upgrading just to get one.

Lmao! Get the 6.2 you'll love it! And for the record my truck managed average of 22 all the way to California. I've gotten 23 several tank fulls there really isn't much to be gained fuel wise on the 5.3 and consider if your towing the 6.2 will hold the taller gears longer up long hills
