4.8 vs 5.3

[vortec4800]

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.

Yep, you've got to lay it on the table.

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?

[bmw 2002]

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.

Ive gone up against 5.3 reg cabs and kept right with them in my 4.8...

[BDBWTE]

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...

[MiSdIrEcTeD_1]

300 straight 6 Fords

Those were pullin little SOBs... Cant beat a straight 6s torque curve... Just ask Cummins or BMW...  :thumb:

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!

[SilveradoWV]

Actually you didnt say it was ext cab until after I posted about it being a V6. Thats possibly why I thought there might have been a V6 in there!
