Differences in 4.8 and 5.3
Performance wise what kind of differences are there between a 2007 reg cab silverado with the 4.8 and one with the 5.3? Is the 5.3 a better choice?

Re: Differences in 4.8 and 5.3
well, being the only one that voted so far...i can say from driving trucks with each engine, the 5.3 is the best feeling power wise. the 6.0 seems kinda weak, but will really go....main thing i like about the 5.3 is the feeling you get when you get on it a bit. of course not to say that you can't get a 6.0 and do a few tricks on it to make it wake up.

Re: Differences in 4.8 and 5.3
Get the 5.3 if you're choosing b/w it and the 4.8. All I had on my '99 was Borla so that didn't really add much power. People were very impressed with it's grunt and get up and go.
Haven't driven a 6.0L though, so I can't talk about its performance.

Re: Differences in 4.8 and 5.3
Meh, it's not a good question. Which is better?
How? Power? MPG? Longevity? Which "better" do you want? That, and how many people have much, if any experience with ALL engines listed in the poll? I've got a 5.3 in my silverado, and my sister has a 5.3 in her Suburban, and those are the only two I've driven. I voted 5.3

Re: Differences in 4.8 and 5.3
I've went head 2 head with a 5.3 with the same bolt-ons as me minus the electric fans. Each time off the line he jumped on me a bit but i reeled him in and got him by about 1 1/2 lengths. From a 25 roll I would get him every time.
I do have different programming than he does, but the big difference I can see between the two is the torque.

Re: Differences in 4.8 and 5.3
haha!!! yeah i wonder if the 6 liter is slower because they typically are in heavy duty trucks and whatnot... my dad has a 2500hd and one time he let me go around in it a few years back with my buddies and i powerbraked it and that posi got both wheels spinning and i was in second gear with the speedo saying 70 when i was doing maybe 15 or something when i pussed out and let off the gas... never did that again cause it aint my own shit to break lol

Re: Differences in 4.8 and 5.3
I drove a 6.0 recently and I agree it seemed kinda weak but so did my 2000 5.3 until I started doing things to it. The 6.0 was in a 2500HD so it had a weight disadvantage from the start. It would be nice if they had a 6.0 in the 1/2 ton line (not the 1500HD).

4.8L 285hp @ 5200 rpm 295ib-ft torque @ 4000 rpm 5.3l 295hp @ 5200 rpm 335lb-ft torque @ 4000 rpm 5.3l ho 310hp @5200 rpm 335 lb-ft torque @ 4000 rpm 6.0L 345hp @ 5200 rpm 380 lb-ft torque @4000 rpm We just received 5 2007 2500hd 4x4s at work and 1 3500hd cab and chasis all with 6.0L they might be lacking in the inital take off but are set up to work not play. I wish I could buy one off state bid I think we payed like 17,100 each for the 2500's.

Re: Differences in 4.8 and 5.3
I drove a 03 1500, 4.8, 4x4, ext cab short bed for 1 week, as a rental, and then had the option of buying a 2000, 1500, 5.3L, 4x4, ext cab short bed. After the first test drive I decided I was not buying the 4.8 L. I believe it is underpowered for that truck. It may be a work motor, but I wanted a little better take off. My dad works with several guys that have the 4.8 L in their truck and I get just as good or better mpg as they do with roughly the same truck setup. I have not driven an 6.0L so I have no input on that. My vote is the 5.3L. Good luck...

Re: Differences in 4.8 and 5.3
I have a 5.3 and it moves pretty quick.
Although I really want to drive the SS with the 6.0L Have you guys looked that the chevy page lately? The trailblazer SS with 395 HP!!! that is insane! they need to put that into the Silverado SS

Re: Differences in 4.8 and 5.3
they need to ressurect the old school smallblock and make a 383 that goes into production cars. you can easily make a towing grunt out of one of them, with over 500 lb/ft of torque, or set it up for racing and make over 500 horsepower instead of the torque lol

Re: Differences in 4.8 and 5.3
well, for a 383, you could take the 5.3(327 roughly), and tweak it yourself. would be a real kickass motor for sure.
as for the trailblazer ss, it has the same 6.0 the trucks and suv's have. now for a real scorcher, take the 6.0 from the c-6 vette's, and put that into an SS pickup or something and it would really kick ass!
