Is the 6.2 a better engine than a 6.0

He said at some point top end changes needed just to push through more air and fuel but, said without hesitating to say do not worry about bottom end it will do it's job.

Now anyone in performance will tell you everything has it's limits even bottom end of 6.0 but, guy was just telling me not to worry for a good while.
This motor has been tried and true for a long long time by the commercial industrial world. It has not had many complaints. I have the 5.3 in my 99 Silverado with 200,000 miles and it has been tuned up performance stuff but, driven like a horse rode hard and put up wet. It runs around 300 to 325 HP at the wheels based on GT TECH PRO and have hard time just leaving stop signs without breaking the tires loose not trying. In a 5000 mile between oil change with Penn 10W30 it will use 1/2 quart maybe. Still drive it everyday and like it with no plans to let it go. It still blows friends minds when they feel it put them back in seat.

What can I say I'm a huge fan of 6.0 and 5.3.

Nice to know I am not the only huge fan of the 6.0 Liter V8. You are exactly right on this engine has been tried hard with the commerical industry, for example, Penske Truck Rental (all there small GMC 3500 Series Moving Trucks have this engine and you know how rental customers are on vehicles, NOT easy)

I know if the 2008 H2's had the 6.0 Liter in it, and having the 6.2 Liter as a "option" I would of gotten the 6.0 Liter.


I am VERY curious on which engine Badance actually got, or considering purchasing?

I just can not go Yellow. No offense to people with Yellow, but I have been in a Yellow Z-71 for a while and need a change. I am going to watch ebay and autotrader, car.com and other outlets for a lifted 07 or 08 and just find the rig I am happy with. Since all of the great things said about the 6.0, I am not as concerned as I was. The 5.7 (IMO) is just crap. I did not want that to be the same with the 6.0 vs 6.2. If I go 07, I will have to put a full rear seat in it. I do like the 07 LE's a lot.

Personally I like the 6.2 with the six speed in the 08 better than the 6.0 in the 06 that I had.

One thing to note though....the 6.2 likes hi test fuel. Mine didnt run for crap on regular. it idled rough and it always felt that it was in one gear to high when you would accellerate. Put in the hi test fuel and it runs like a scared rabbit!

I think they are both GREAT engines. You don't see many threads about engine problems with the H2 and I saw an '03 H2 at an offroad event with 115,000 miles and the owner said the only problems he had were with the ignition switch and the front windshield leaking (but I doubt it was the original). Most of the H2 threads are about electronics. I can attest the 6.2 runs much better on premium than on regular.

6.0 is a great engine with a SC but if its power you desire then install the Corvette Engine and SC it.!

I have an 06 with 6.0 engine and an 04 Chevy Express work van with the same engine. The Chevy has 93,000 and hasnt had any engine trouble.
