Chevy 6.0 vs. 5.3?

13 posts in this topic

My kids are outgrowing my extended cab.....I had aspirations of driving my truck to 3-400 K but I guess someone else can wink

So I am looking at buying a chevy crew cab. How much difference in performance is there between the two engines? I tow a 18 foot crestliner and am sure either would be fine for that but at some point I will buy a wheel house and don't want to regret the decision. I'd appreciate some pro's and cons that I might not be thinking about.

Lets stay outa the other brand debate please whistle

My little brother tows a 29 foot travel trailer with a 5.3 suburban and has no regrets. That is a 327. I can only assume that the bore and stroke are the same as the old legend. My math tells me that the 6.0 is a 377. Good engine/more torque but will use more fuel. The 6.0 did have some issues when first introduced but they have addressed them and now it is pretty much rock solid. Both have the same tranny. I believe you have to move up to the 8.1 or the Diesel for the Allison.

My uncle has the 6.0 and it is a pig on fuel compared to the 5.3. He gets about 11 with that beast.

I have a 5.3 and pulld my 16 ft boat and the mileage is approx 16-17 depending on how I drive. Plenty of power to tow this boat.

I have owned several 5.3's and 1 6.0 and I liked them both. The 6.0 seemed to have alot more torque and was geared more for towing and work. The 6.0 was rated at 300 h.p. and the new 5.3 is rated at around 310 or so. For your application, I would say the 5.3 should do nicely for you not to mention the extra fuel economy when your not towing. I got around 16 with the 6 litre unloaded and I currently get between 18 and 23 with my 5.3 Silverado unloaded and depending on the wind. I pull my SnoBear (3200lbs,) with the 5.3 and don't have any problems and still get around 16 m.p.g. Hope this helps!

I have a 2003 6 litre Silverado I get 12.5 around town and 15 hwy.

If I load it up with my 27' Sportcraft I get 11 mpg... but you can bet it sure does a good job!

I dont tow the boat anymore and was thinking of unloading the truck and found out it was worth about 12K I think I'll keep it!

I have a 6.0 in my work truck, duramax as a all around truck and my fiance drives a suburban with the 5.3.

With the 6.0 I get about 13 on the hwy empty 10 in town and 9 towning anything.

The duramax gets 19.5 avg. on the hwy, 16 in town and 14 towning.

The suburban gets 18 on hwy, 13 in town and around 13 towing.

If I were you and you don't want to just to the duramax, I would go with the 5.3. Plenty of power and when you are not towing you will get the bonus mileage.

A suburban might not be a bad option either as one can purchase some pretty nice used ones for a real fair price. Nice when a person wants to go fishing with a group too.

I'm going to reflect the exact same sentiments as Outfitter.

My best friend has the 6.0 VertecMax engine (345hp) and gets 13 - 14 highway, 10 - 11 city and 9mpg regardless of what he is towing. That engine is a brute and will pull just about anything and then some. Will suck gas too like a bad alcoholic! laugh

I've got an '05 Silverado 1/2ton CC with the 5.3 and just love it! I pull my 18' Alumacraft around no problem with that truck. In fact, it pulls better than our '05 Tahoe that has the same engine (might be geared differently). The 5.3 is a workhorse. I get 17 - 19 on the highway, 13-14 city and 13 - 14 pulling the boat up to and back from Canada this year. I couldn't be happier. cool

I've got a 4.3 in an extended Silverado. Yesterday on a bad ramp, I had trouble for the first time ever pulling my fat glass boat out of the water. Perhaps if I had some box weight it wouldn't have been a problem.

I've also got a Suburban with the 5.3. It has performed as expected and the mpg hasn't been the worst. We recently pulled a 5,000 travel trailer to Wisconsin Dells. I mostly ran around 60 mph and had no trouble tromping on it to get out of traffic trouble.

Thanks for the posts, the 5.3 sounds like it will fit the bill.

    • And if the leftists get lucky at the convention?     You aren't against human rights, like income, health care, equality, LBGTQ rights, and stuff like that, right?  
    • You scale them, no?
    •   So, why bother with locks?  Honest people won't take your stuff even if the door is unlocked.   I am in the camp that I want to make it at least a little difficult for the crooks.   Especially since three people in our family have had their houses burgled and stuff taken.
    • The result right now is not good. One way or the other the toilet needs flushing
    • Mostly I talk about this with respect to the nonsense about multiple parties or no parties some on here seem so fond of.      It is all a fantasy.   Some new party could possibly take over an existing party, like Trumpism did, or even replace it like happened back in the day but in the end there will be two parties.     Perhaps a parlimentary system with multiple parties would be better than what we have, but, in my opinion, you can't get there from here.  It's like the calls for a Constitutional Convention.   Do you guys seriously think that could happen, and that the result would be good?  
    • I haven't gone up the old Grade, but do head to Outing via Emily and NE from there, and it is really nice. Hardly any roads to go across and little to no ditch riding. I have got to try the Old Grade, as I would think it is like that. We grouse and duck hunt up there now and then, but haven't lately. Great place with lots of public land and opportunity.
    •   But yet I countered with an actual study but you think your own speculative based opinion is better. OK then.     How very hypocritical.      I would end the discussion after that last statement too.
    •     I can guess it is not for humanitarian reasons.   Mexico has about had their fill of fighting the drug war for us, and are moving towards decriminalization.  If California legalizes weed, this would be enough to tip the scales in favor of decriminalization for Mexico.       For years now, Mexico has paid an extraordinarily high price in lives and social disruption for Washington’s insistence that North America’s drug problem be tackled south of the border, where the drugs are grown and transported, rather than primarily in clinics and halfway houses at home to treat the medical and psychological issues of users. Mexican President Pena Nieto.   Successive administrations, starting with President Nixon, have demanded ever-tougher border controls, aerial-spraying programs, and DEA-backed anti-“cartel” operations in Mexico. All those efforts and sacrifices have been for naught. U.S. residents currently export up to $29 billion in cash to Mexican traffickers each year to buy marijuana, cocaine, methamphetamines and heroin.   Forcing that trade underground has taken a terrible toll on Mexico in terms of violence, corruption and social upheaval. Since 2006, when President Felipe Calderón ordered his military to join the “war” on drug traffickers, Mexico has lost about 200,000 lives and 30,000 more have disappeared,dwarfing the civilian death toll in Afghanistan and Iraq over that period.   The majority of those killed and disappeared were victims of criminal organizations, but human rights organizations also report soaring rates of human rights violations, including torture and killing, committed by security forces.   The 2016 Global Peace Index, prepared by the Institute for Economics and Peace, estimates the total cost of violence in Mexico at $273 billion, or 14 percent of GDP, with no end in sight. Direct fiscal costs of fighting the war on crime were about $32 billion in 2015 alone. Yet the United States has contributed only about $2.5 billion since fiscal 2008 to Mexico’s drug war, under the so-called “Merida Initiative.” Mexico’s pain shows no signs of easing. The New York Times reported in December that Mexico suffered more than 17,000 homicides in the first 10 months of last year, the highest total since 2012. “The relapse in security has unnerved Mexico and led many to wonder whether the country is on the brink of a bloody, all-out war between criminal groups,” it said.    
    •   But In Del's defense, he only does this on things he would like to stay as is. When you are talking about legislation he is in favor of then it is the law of the land and can't be changed. When it is something that he dislikes, it can and should be changed.
