4.8 vs 5.3


Recommended Posts

Posted

So how much quicker is the stock 5.3 to the stock 4.8, because when I looked at the specs it didn't seem to have a very big power increase, and I was wondering what it did to the 0-60 times and what not.

 

I have no doubt that its quicker, its just overall a beefier engine. But I have a 4.8 and I need to feel good about myself SOMEHOW...  :)

Your 4.8 is a great motor!  I doubt there's a huge difference in acceleration between the two plus you'll get better mileage due to the smaller size.  The main difference you'd notice between the 2 engines is with towing.  The 5.3L makes more torque at lower rpm ranges so if you need to tow anything I'd recommend the 5.3L. :thumb:

No matter which is faster...the real question is...

 

Can either keep up with my Odyssey?

 

you know what im talkin about (and so does that guy in the blue sierra) :)

Did he know you were racing?  It doesnt count when the guy could care less and is just out for a drive and you decide to mash your pedal.  He was probaly to busy laughing his butt off.  :)

No no, I was there... And as much as I hate to admit it the sierra was racing (he peeled out like none other) and the van kicked his ass...

 

 

But what happened to comparing the 4.8 and 5.3?

sorry bud, i ruined your post :)

 

 

But, long story short, the guy in the truck was being a cock anyways so he got his ass handed to him like he needed :)

 

Anyways, does anyone know the acceleration times on the 4.8 and 5.3?

CapnDean's butt dynamometer sez:

 

"The difference between the 4.8 & the 5.3 is hardly worth notice"

 

Allow me to qualifiy this:  2001 GMC ext cab 4.8 vs 2001 Silverado ext 5.3  -- Both vehicles 2wd and essentially the same.  I honestly cannot tell the difference in acceleration.

 

They are both stout motors....  Maybe towing, the 5.3 is a little more gutsy....Hard to say because when I am towing with EITHER vehicle I don't punch it or look for acceleration.

 

Feel good about your 4.8.....mine is punchy and gets excellent mileage to boot!

How do you know he wasnt running a 4.3? In that haevy of a truck the 4.3 isnt all that great for racin IMO, not bad for a daily driver though!

Do they put the 4.3 in the extended cabs?  i always thought the 4.3 was for like single cab, short bed and the s10's.  I guess there is a chance he could have been running a 4.3 but from the sound of his truck (which obviously had intake and exhaust work, which sounded very pretty) im taking a big guess that it was a v8 in there.

Don't knock 4.3's they are bada$$ little motors....they hold their own in acceleration and towing compared to the competition....I'm not huge on numbers written on paper or for this purpose the internet..I've need 4.3's tug 4.6L Triton Fords and 300 straight 6 Fords and many 5.2 Magnums.....I know their abilites...

Sorry, I missed the ext cab part! VERY unlikely a V6 would be in there!

 

I wasnt knocking the 4.3 at all, it is a 350 with 2 less cylinders, and beats alot of the competition!

    • Here's the 2026 order guide - Vehicle Order Guide   RPO code "AS3"?  Not seeing it.  What is it supposed to be?  I see AS3 used a long time ago as some sort of seat option, but its not applicable to the current Suburban.    I see RPO code "AZ3" which is 1st row 40/20/40 split bench.  That is only on LS trim, which LS can't option any of the trick suspension.     2nd row bench power fold RPO code is "ATT".  So your dealer should be able to sort their locator to find matching builds by searching the combo of ATT and Z95 combined to find a 2nd row power fold with MagRide.     You can do the 2nd row power bench AND have MagRide, or Mag with Air on Z71, RST and High Country.     Here's a Z71 with 2nd row power bench and the Z71 Off Road Package which adds the Adaptive Air and MagRide - 2026 Suburban | Details | Vehicle Locator   Here's an RST with 2nd row power bench and the RST Capability Package, and RST Capability adds the Adaptive Air with Magride - 2026 Suburban | Details | Vehicle Locator   I can't find a High Country, but you can do it on there.  Requires the 6.2, and the Sun and Tow pack which allows you to then option the 2nd row power fold.  Black interior only.  High Country comes standard with MagRide and you can order the air if you get the High Country Deluxe, but Deluxe will take you to captain 2nd row.       You can do it at GMC on the AT4 and the regular Denali (not Ultimate) as well.  
    • So.  Get this.  On the Chevy regular cab, you can get the factory remote start at the dealer from the accessories catalog.  BUT.  GMC, you can't.   Now...get this...GMC 2 door, you CAN get the power seat.     Go.  Figure.   Anywho.  are you trying to order?  Or locate?  Ordering for 2 door 1/2 tons has been stopped as of April or May?  So you won't be able to order.  You'll have to shop on the ground units or in transit units.     Ordering was stopped because the new trucks are coming.  
    • Thank you.  I really appreciate the well wishes.  I'm an engineer in the telecom industry, I know hardly anything about marketing.  Over the years I did some videos for nonprofits and web sites for small businesses and the seed was planted.  Agree with over-buying, I started shooting on an iPhone before I got my first DSLR and tripod.   I'm looking at trucks with potentially 150,000+ miles to keep the cost of entry low while focusing on the client experience and equipment.  Good wireless mics for interviews, the right lenses & lighting to look professional.  But I don't want to be late or break down, the stress of emptying a trailer & securing a rental truck right before a gig would negate any savings from buying a junker.  So anything that leaks water, has extensive rust, or generally unreliable I'd like to avoid.   Does GM/Chevy overbuild these trucks for upfitting?  I talked to a local upfitter, they sometimes tie lights & other 12V into existing circuits, which I always thought was bad.  Which is why I enjoyed the AUX upfit switches on previous trucks (odd they mostly come with off-road or work truck packages).
    • i guess it might be depending on the type of driving. my 2.7 has 120k miles, changed the plugs at 70k and it runs as good as new. i have not used any injector cleaner
    • GM's are stainless and have a fairly robust powder coating, although, still not worth $850 in my opinion. They will hold up a lot better than their cheaper steel aftermarket counterparts.   What I like about the GM step bars is dealers will often equip their dealer stock with them. Lots of margin. Which means a lot of people end up buying them because they're already on the truck, even if they don't like them. So it's pretty easy to find brand new takeoffs with hardware on Marketplace and Craigslist for about $250.   That's what I did for my crew cab. I wanted ZR2 rock rails for the look, but with the ability to bolt up GM's assist step package. From GM it's about a $2500 accessory all in. The old folks in my life can't get in the truck without steps. I found the whole package on marketplace for $180.
