98 silverado with 5.7 seems fast.

[chevythunder98]

hey guys im not really all that savy with the actual know how and experience but i know quiet a bit in theory and i was wanting some help. i have a 98 silvy with a 5.7 i bought it a 100000 miles from a old man and goin from a 94 ram with a 5.2 in it it seemed like i was drivin a race car but then when friends and stuff started ridin with me and i would show off a little they all kept saying that this truck was wicked fast for being a stock motor my question is is there any way for me to tell if it truly is stock or if its had any internal work done. theres no bolt ons on it and it still shuts off at 98 so im assuming no tune. but i can wax other 5.7s and some 5.3s all day long so any help or hints appreciated

[silverado_lover]

subbed

[dirtyhick42]

Do some 5.3s actually turn out to be v6s? I dont see you waxing them.

[Snowboi]

What about the fast 2.4's, do you wax them?

[silverado_lover]

Wanna race another 5.3? :naughty:

[dirtyhick42]

Or a 2.8?

[Tahoejoe99]

Being that It came from an old man, I bet it's never been reved over 3k. And just cause it shut off at 98 don't mean it don't have a tune, or gears for that. Pics of the motor would help. Pop one of the valve covers off, look for any clues of mods. Have you checked under the seat for a couple of midgets running flintstone style?

[Outlawz2004]

Someone probably regeared it giving it some pep. Why not take it to a local dragstrip and get some real time numbers on it? How about a quick 0-60 video that you can post on here.

[chucksrt]

So what are you guys saying? That not even a modded 5.7 can hang with a 5.3 or that there is no way a stock 5.7 can play with a 5.3? I find it hard to believe that the #1 modded engine of all times would have a hard time pushing out enough hp to leave a 5.3 sitting?

[Quyonmob]

Nobody said that.

The #1 modded engine of all time is 5.7L L31 Vortec? OR is your comment just based on the 5.7L of displacement in the bottom end? Cus that certainly isn't a fair comparison (80's smogger 350 vs a 5700 Vortec).

Plus the venerable 5.7L bottom end has about 50 years more history than LS blocks. :D

[kemble]

Next time make sure the Gen III powered trucks know you are trying to race them.

All i'm saying is that the SBC has been around and has plenty of options to make it stout. Sounds like your saying that the vortec design is the main reason for it's limitations? They do have performance intakes and fuel delivery setups that can allow the 5.7 to be a contender. I personally have a 383 in my conversion van that moves pretty well for something it's size. (may even surprise a few people) and I will be doing the edelbrock Pro Flow intake, TB and fuel rails soon. I just don't think it is unheard of to see a modded 5.7 on the road!

Here we go, another fool with a conversion van that raves about a 350.:nopity: Yes you can mod the crap out of a 350 and make power, but it doesnt take much on a 5.3 to make it a street burner. Is it unheard of to see a modded 350, hell no. Everyone and their brother has one in their yard. This conversation is about this one specific 350 seeming faster than other stock 350s. OP, you got that 0-60 video yet.

[chucksrt]

Who are you calling a fool! You don't know me. All I am saying is the holier than thou attitude this thread has for the 5.3 give no respect to the 5.7. I give two craps either way! My conversion van is just something to tailgate with. If your 5.3 wants a race I have a 2.2 4 banger that would slap you all over the place. You can hop back on your horse now! LMAO

my signature describes you to a tee.

[Outlawz2004]

I dont have a 5.3, I have a 4.8 thats quicker than most 5.3s here LOL. I also have a quick 4 banger, along with a hemi charger RT, just sold my built mustang, had a 1957 belair built for the strip, etc etc etc. Calling out someone for a race when you across the country makes no sense. If you were near here, I would surely meet you and your 350, 383, whatever at the track. I have been called out before, unlike some people I will actually show up. The 350 vs 5.3 arguement has been done a million times, no need to bring it into this thread. I have owned several 350s, they have their place. Compared stock for stock for speed, the 5.3 will win 99% of the time. Mod for mod the 5.3 will win. Throw a trailer behind them and its 350 all day long due to the torque range. I am a fan of both engines.Everyone respects the 5.7L, but its not the best at everything, neither is the 5.3.

So please chucksrt, carry on.

[S.Wells]

Could have a mild cam in it and some head work done. Will turn a 5.7 into something proud to own. Would love to see that 0-60 video.

I can pull down my pants and say mine is bigger all day long, but all I was stating is that you call someone a fool without knowing them. Due to the fact that you are across country and that doesn't make it right. Again, all I am saying is that someone post that their 5.7 is fast and some 5.3 guy comes on and puts it down. I am not the biggest fan of the 5.7 (as it in stock form needs a ton of mods just to handle higher hp) but as it is and with mild upgrades it is a good dd. I was surprised to find out that this 8cyl. pretty much needed to be completely replaced if trying to get over 700hp out of it when my Daytona Iroc R/T's 2.2 can handle 700 with a factory block. My van is a odd toy. I like odd toys! It's not a race car or even a dd for that matter, I built it just because I could. So op I'm sure your truck is quick and may even surprise a 5.3...who knows? So that's my rant and now I will "carry on" lol

It has been around forever, hence making it the #1 modded motor of all time, give the LS platform another 50 years of history to make it a fair comparison.

I'm not saying the vortec design of the 5.7 is the limitation, though it does have it's shortcomings (stock fueling via poppets).

I'm all for building what you've got, and absolutely a 5.7 sbc can be built to beat an LS. Plenty of built 5.7 sbc's to prove it.

That being said, I do love my Gen III though. :D

[kemble]

For goodness sake just take it to the track, make a few 1/4 mile passes and see what it has. Quit quessing or listening to your friends butt dynos.

[96ImpSS]

I'm with the OP. My 98 Silverado with 5.7 seems fast too! :D
Seriously though, comparing it to a 94 5.2 Dodge, it WILL seem fast.
I know the 5.3's have gotten better with a few more ponies over the years, but back when mine was bone stock, the 1999/2000's 5.3 pickups were no match for it from a low speed dig. From highway speeds, they seemed equal.

[silverado_lover]

I had a mild 350 and now a 5.3 with LT's and a tune...I had more work done on the 350.

The 5.3 is a damn rocketship compared to my old engine.

[bigwhite00gmc]

I can vouch for chevythunder, known him for years. His truck is quick for what it is. It's beat a programmed 4.8 4wd no problem. It can walk on my 5.3 easily, and I've seen the truck nose out a few stock 5.3 trucks. We both believe the truck is all stock motor wise, it looks, revs, acts just like a stock 96 I had. I'm not saying this truck is an ass whooping machine, but give the truck it's due for what it's capable of. We all know the 5.3 can make power easier than the 5.7 vortec but chevythunder puts up a good fight for his stock truck.

Ok, a "programmed"(crap)4wd 4.8. heavier, smaller engine, less torque down low, and let me guess it was a 99-02 model to top it off, the lowest output models. Your 5.3 is also one of the lowest hp 5.3s if your truck is a 00 model. All that aside, there have been a few 5.7s beat 5.3s, everyone knows that. Its not commonplace however. No one knows the specs on most of these trucks, for all we know they are running 3.23 gears, etc. Driver error also comes into play. Just post some vids of the truck, thats all we are asking being that he came on here talking about it. Take it to the track, get some real world numbers. No disputing that. Alot of people "feel" that their truck is fast, get to the track and not break into the 15s. It happens all the time. Like I tell people, my trucks not fast- its only runs mid 14s, but its faster than most of the stuff running the streets around here so it has a reputation as being fast. A slow truck beats a few other slow trucks and all of a sudden it badda$$. Not saying thats what is going on here, but thats what tends to happen.

[Southernboy2147]

I agree with outlawz. I got a 99 single cab Z71 with the 5.3 and it is slow. my buddy has the exact same truck with same size tires and all except its a 05 and he waxes my ass.

[kemble]

ONE MORE TIME . Quit with the it beat so and so, or ran away from this or that truck. RUN THE TRUCK, get a timeslip then talk more.

[chevythunder98]

wow you know i got on here with a geniuine question hoping for some serious answers i admitted to not knowing much about how to tell if my truck has anywork done to it and it seems all that happened is i p*ssed off abunch of you 5.3 boys i actually thought that i would get some serious mature answers from this forum but obviously not.

[Outlawz2004]

Still interested in seeing some 0-60 videos. I dont believe anyone is "pi$$ed" off, just curious as to whats it will really do.

There is no way of knowing what is done to it, without actually tearing it apart or finding a previous owner who did any work to it. Just saying it feels fast is not enough info. Fast is a relative term, what I think is fast is totally different than your fast. My 04 runs 15.2 and I think its slow. Although pretty quick for what it is still slow in my opinion.

As I have previously mentioned, get a timeslip, then there is no speculation. I am not pisssed off, just cant fathom why this seems so hard to understand?

Yes, they upload very similar to a photo, just take a tad bit longer to load. You can post them here the same way using the link provided on photobucket. I think you posted them before, but post the links to the pics with the 33s too. Curious to see if they looked stuffed or not. They dont appear stuffed too bad in your sig pic.

ok i really wish i could have got a video of her with a set of 235s but when she was gettin raced it was on 235/75-15 camanche street tires now shes sittin on 33x12.50 mts its bone stock with 3.42 gears im still proud of it but i sure do miss how ballsy it was with little tires

I never said either truck was fast or slow... I said they seemed the same. Seemed to rev at the same rate although the op held his rev to get a higher shift point? The op speedo was not working regardless.

Best i could tell on the op's video, looks like his truck does 0-60 in about 10 seconds. Seems like a normal time for a stock 350. The tire height probably throws it off a little so maybe high 9 second to 60.

He should be able to beat you, a 2000 ext cab on 35s,11 inches of lift and 230,000 miles on it. OP,Please find some stock tires, take it to the track and get some definite numbers. I would put money on it that it runs in the mid to upper 16s.

please list the mods. Either you have a ton of mods, you played with your tuning software to make it appear faster, or you swapped in some low a$$ gears and didnt retune for them. Give up the goods on it. My bet is on the tuning software being adjusted because the truck(or is it a suburban that your own) doesnt even sound like its hauling the kind of a$$ its showing.

It a suburban, mostly stock with a ramjet cam and a 3" 40 series. I have 2.73 gears out back on 33's to help exploit the insane low end torque and it goes 0-60 in about 4 seconds. Why does that sound suspicious?

It a suburban, mostly stock with a ramjet cam and a 3" 40 series. I have 2.73 gears out back on 33's to help exploit the insane low end torque and it goes 0-60 in about 4 seconds. Why does that sound suspicious?


0-60 in 4 seconds?

Let's look around ...

2011 BMW M3. 0-60 MPH in 3.9 seconds...
2012 Nissan GT-R 0-60 MPH in 3.2 seconds...
2011 Corvette ZR-1, 0-60 MPH 3.3 seconds...
2011 Corvette C6 Z06, 0-60 MPH in 3.6 seconds...


So what you're telling me is that your Gen II Suburban is running within milliseconds of some of the world's highest performance consumer automobiles--most of which have higher torque, horsepower, lighter weight, better transmissions, launch control, professional drivers, or a combination of all of the aforementioned?


Bullllllshiiiiiiit.

I wish I could find the dyno chart comparing the 5.7 tbi, 5.7 vortec, and 5.3 vortec engines. I have seen it a few times and the numbers are surprising. The 5.3 holds around 250-260 Ft pounds of torque from 2800 rpms to 5000 rpms. Granted the test started at 2800, but still the curve isnt gaining fast so this leads me to believe the torque is at least decent before 2800. It just feels different than 5.7 trucks because the power INCREASES as you rev the LS engine, unlike the 5.7 engines that die out the further they are pushed.

LS comes alive, 350 dies.

Only thing insane is the person who thinks a burb with those mods will 0-60 in 4 seconds IMO.

No, the OP said his truck seemed faster than others and tried to give examples. He was asked to post a quick 0-60 video in order to give us a better idea of what he was experiencing. We didnt say make a fake video and post that and everyone will believe you. There have been people in the past that have posted fake videos, claimed other peoples videos,etc. They usually get caught. I believe Ezkieler850 was just doing it in good fun though. I believe several of us have also suggested an actual time slip would be the best thing. If you have any integrity at all, you will not post fake videos or other peoples videos.

Alright, it's possible I might have 3.73s instead of 2.73s and I might have tweaked the speedo calibration just a little.
