So I traded in my 04 2wd Crew Cab Silverado for an 05 ecsb Z71 Silverado with the 5.3 H.O. It is dark grey metallic with charcoal cloth and a 3.42 rear. After putting a few miles on it, I've already noticed that it feels stronger than the flex fuel 5.3 that was in my crew cab and sounds a bit louder under acceleration. It also shifts quite a bit smoother.

 

Sweet! If you are close to LA, I know where you can get a deal on a Radix

 

What are the power ratings for the 5.3 H.O.

 

310hp/335lb.ft.

 

I have a 05 ecsb L33 3.42 and my close friend has an 05 crew with 4.10s and stock vs stock I pull away from a stop to 80mph. now i have hptuners and have upped the shift points and removed tqmgmt its even more noticeable

congrats on the new truck

 

congrats

 

Nice huh? They will stink at first while they seat in.
The only problem on mine was the cat pipe to muffler pipe connection. It leaked between the flanges on the bottom. Took it in and they fixed it. Got a Corsa Touring on now.
It shifts faster and firmer than previous years, you agree?
If you would, look at your glove box RPO code sticker and tell us if you have the M30 or M32?

 

congrats on the new purchase.

how do you like the 3.42's? what gears did you have before? what do you like better?

 

Is it really an aluminum block?

 

Nice truck. Sounds similar to mine with options, color, etc.



Excpet for your fancy electric fans, better heads, aluminum block.......
You think you are sooo cool.

J/K- Nice truck. I have been meaning to test drive an 05.
