I no longer own my 2000 silverado, (wish I would have never bought it)
I now own what is in my sig, and truthfully, I can say that the 5.3 would get up and go only slightly faster than what I have now, and it only got about 1-2 mpg more depending on how I drove it.
I for one believe that Chevy made a HUGE mistake dropping the 5.7 Vortec. They had a good thing there, and they let it go.
Just my 2 cents.
Again, sorry to dig up the old post...

I agree...My 5.7 Vortec extended Kicks serious ass...my friend has a 5.0 or 5.3 not sure but it's the same year as mine just single cab, I smoke him every time..lol

yes I've seen the SS Truck... the price tag is almost as ungodly as the horsepower!!!!

Everyone else is throwing the 350 in as a standard and tuning it way down to 345 horses I guess for mileage and emissions... Either way the GM needs to get back to the big horse motors and put some name on it like "Panty Dropper V8" and maybe that will get a similar market that the dodge captured with the HEMI tag!!!

Here's a simple solution, if they remade the 5.7L with some of the newer technology it would prolly come with right around 290-300hp. Sooo then just sell a 5.7 with a supercharger on it. A small SC would add very little to the cost of a truck and boost the power up to around 400hp.

Well they're gunna pull themselves out of the hole they dug somewhat, seeing as they are turning the Silverado SS into 2WD only. It's still gunna have the same engine but the 345 horses can be put to good haulin' ass power now.

Silverado, GM has the SS Silverado with a 6.0 in it. They stoped making 5.7 becuase they found they could get more power from the 5.3. There is also the Joe Gibbs addition that has a 4.8 supercharged.

[Silverado Brethern]

Yeh the 6.0L is a good engine but a 350 can make way more power than a 327. How much horsepower does the gibberado make? but that truck still is nothin compared to the popularity of the lightning or even the hemi.

How i would love to supercharge my truck, but thats like 3Gs

Ol' Gibby's Silverado makes 390 hp and 425 lb-ft of torque out of the standard 5.3L, although if you put the same blower and intercooler on an SS with the 6.0L you could most likely get even better numbers. To me the having the letters "SS" on your truck mean alot more than having a little plate that says "Joe Gibbs".... most people have no clue who he even is...

Had to google it find out who he is...LOL

My point exactly..

I own an 05' Sierra and I love my truck alot but I'm not blind to the fact that the Dodge Ram Hemi is faster. I have a CAI, Dual Flowmasters, and a Diablosport Power Programmer as far as performance mods go. I have tested my truck out and so far my best time is a 15.6 @ 86.8 mph. I would venture to say I am probably as fast as a stock Hemi. As far as everything else I have an 0/2 drop kit, 22" GA chrome rims, chrome mirror covers, chrome door handles, debadging, aftermarket oxford burlwood Denali dash kit, LineX spray in bed-liner, aftermarket DVD player, custom leather 2 tone interior, and many more mods. Concerning the 5.7L, why would you even compare that engine to the 5.3L. The 5.7L only cranks out 255HP and the 5.3L puts out 295HP and manages better fuel economy in the process. If you want to talk a good GM engine then talk about the 7.4L 454 that was put in the old Suburban's (torque beast).

I'm thinking that this ancient thread has been resrruected just about enough already.
